Engineering in Games: The Helldivers 2 Hellpod
HTML-код
- Опубликовано: 20 окт 2024
- Helldivers 2 has taken the gaming world by storm. It has also taken all of my free time because the game is incredible. So, I decided to put my skills to the test and looked into how the hellpod is likely designed. No lore exists from the developers so I worked through the math to figure out how it would work.
#gaming #helldivers2 #howitsmade #lore
Engineering undergraduate student here! I think you may be over estimating the heating that the Hellpod will have to endure. Super Destroyers don’t orbit planets, they hover above a point relative to the surface of the planet! That means no lateral velocity needs to be shed!
That would mean that you only need to determine the gravitational potential energy of the Hellpod at an arbitrary altitude then use that to find the velocity before it hits the Karman line. The speed shed by drag before reaching terminal velocity could be used to determine the heat energy the pod would need to withstand.
TLDR; Hellpods don’t need to withstand a full orbital drop.
I also wonder what the Helldiver's suit itself might do to help mitigate the g forces, it might be possible the hellpod and the divers suit work together is some way. Not 100% sure, obviously just a possibility done with better knowledge could figure out, lol.
I like your profile pic
Always bugged me that they say the destroyers are in orbit (when time runs out for example it says "super destroyer leaving orbit")
@@alongal407 I think it's not a small stretch to imagine that orbit might become a colloquialism that loses its original meaning, but that's just me making stuff up.
@bob38028 argument fails 2:24 the hellpod is the mesosphere so it just entered orbit
I'm pretty sure the game has some random note about the hellpod having a shock absorbent material in there so the helldiver doesn't become a hellpancake.
The super destroyers seem to have artificial gravity, so the hellpods could have 'intertial dampers' using the same technology.
@@thomasp506yeah. Pretty sure every hell pod will have some balogny space magic inertial dampener tech. Haha.
@@ch4osaeternum74 It might not actually. Some of the upgrade descriptions talk about shock-absorbing springs and gel. So I guess it's more cartoon logic than space magic.
Superpancake*
@@thomasp506 I think they just hover 5-10 km over the battlefield
Single-use troop deployment... S T D
Bam, solved the acronym
That is a delightfully accurate description of Helldiver's too, in a sense. It's perfect, lol.
That's perfect I see no problem
I prefer S.O.D Single-Use Orbital Deployer
There’s a lot of STDs on my ship
Helldivers here to spread Democracy... among other things
I love the contrast between scientists and engineers. Mostly, how engineers just say "eh it's close enough, I'll get thr right result 90% of the time."
As a physicist this indeed hurts physically. But ig i could be worse off, could be landing in a hellpod...
As a quantum physicist, I understand your pain. Bit ironic considering we pretty much deal with nothing but probabilities, but it is what it is.
@@Zane12ai remember, e² = pi² = g, therefore e² = g
The point of Engineering to deal with uncertainty. The point of science is to reduce uncertainty.
Bullet + You = Hellpod. Easy.
Eloquently put. You have great potential in the engineering corps of super earth!

What occurs to me is that given the rising motion, it's likely that the passenger in a hellpod doesn't stop all at once, picture a set of ultra resistant springs below the helldiver's 'floor' plate, that spread the 'time to stop' out over a longer amount of time for the passenger as opposed to the pod. This would cut the effective G force substantially. The now compressed springs could then provide force for the rising of the platform to eject the Helldiver from the pod. Other's have brought up this idea and I think it has some value to solving the engineering issue of 'unsustainable G forces on passenger' we're encountering here. Combined with lightening the pod itself and just a smidge of "I don't care about the long term damage." dedication to the cause, I think it's solvable.
Minor (nerdy) correction: the heat experienced during atmospheric entry isn't caused by air friction. The air in front of the entering object is actually getting compressed as it just can't get out of the way fast enough. And of course, when you compress a gas into a smaller volume, the temperature must increase 😊
I was looking for this comment! Nerdy, yes, but appreciated!!
I have come to help the algorithm. I'll remember this info if I make a game involving space.
Thanks Zach!! Appreciate the support. It legit looks like you may have helped put it into the algorithm some more!!!
Also if you ever need some engineering math done for that game you’re looking to make let me know!
im doing my part for democracy... aare you?
Helldiver's are actually 7 feet tall, they mentioned the hight in the training section.
Dang!! I totally missed that in the training. Thanks for the heads up.
To account for that I’d say add an extra foot to the hellpod tube, add about 500 pounds maybe.
Brasch just said the player reminded him of him in his own prime: 7' tall and indestructible. As he's still alive, Brasch can be said to be a considerable outlier among Helldivers and can be disregarded safely.
Nah, they are not space Marines. They are disposable single-user soldiers with minimal training
@@tedarcher9120”minimal”
they had military conduct and arms manipulation trained since they got out of diapers
they were briefed on how to use stratagems, each one
they were briefed on enemy types, even if very briefly
they have a significant, impressive physique
it’s at least 20 minutes of specialized training, and years of indoctrination
@@folou9199 years of indoctrination famously can beat months in training, that's how Hitler won the Battle of Berlin and established the Fourth Reich
Fun fact: if you rotate the ship, the hellpods are now boarding torpedoes considering how they dig into the ground...
That is, honestly an incredible idea lol
Helldivers exit the hellpod through the top, so that might be an issue if the pod doesn’t pass all the way through
@@herbertpocket8855quite clearly liberty will save them from the vacuum of space! Democracy protects.
@@herbertpocket8855 Perhaps there is another variant of the hellpod where the bottom of the pod pops off when embedded into another ship and allows the Helldiver to climb out.
And then the helldivers fall out the side of the ship?
One thing i noticed when upgrading the eagle modules. It says something along the lines of having the pilot suspended in some special liquid that helps them pull higher G's in corners. Perhaps that would be used here?
It's a "breathable fluorocarbon" that gets pumped into the cockpit, would definitely help here. Also something to note, apparently the hellpods are steered by foot-accuated levers, which implies the helldiver would be taking in a good bit of the force from the impact straight into their legs.
A little late. but that’s different that’s reducing the amount of Gs for sustained tunes. which in real life the best pilots can handle a few seconds of a 8-9g turn before passing out. So the gel wouldn’t do much in terms of that seeing as those 100Gs are instantaneous instead of like it is in planes where it’s a lower number just for more time
You got me convinced triple the defence budget
"Feral engineering" is the greatest phrase I have ever heard.
Drafting Design engineer here. Loved the video.
One thing ive noticed is the hellpod has airbrake fins that pop out on the top that could also help slow the pod down. Much like the control surfaces on the falcon rockets spaceX developed. Lets say that slows the pod down enough to remove an additional 20 g's. Also, you could theorize that the vertical deployment system for the helldiver is also a shock absorbing system. Which could decrease the g forces down to survivable levels. Seeing as you'd only need to bleed about 60g's from the impact; hellpods could theoretically be survivable.
Now who wants to band together, develop this, and get a government contract for deploying weapon systems to our troops from orbit? 😎
You should do a drop pod cross-over video with Installation00.
He probably love that
I haven’t seen his stuff before! Thanks for the suggestion! I see he has a bunch of halo videos so I’ll totally be sitting down and watch those now lol. Love me some halo
You didn't take into account the increased drag from the opening of the side flaps after you're out of atmospheric entry.
For a real Hellpod to work, the retro/thrusters would need to go online before what it is shown in game.
The real calculation is to figure out how high you'd need to deploy flaps and thrusters to slow down the hellpod enough for it to experience at most 10G of force when stopping. 10G is easily manageable and with training that is what fighter jet pilots and astronauts train to endure.
Edit: also there are shock absorbers that could be in place inside the hellpod to further decrease the deceleration and reduce the Gs experienced by the helldiver, which is also in canon that the hellpod does have shock absorbers to prevent a hellpancake.
Edit 2: Also, at least show on screen metric so we can follow along and try to help. With imperial you are basically limiting this to only USA to be able to help solve, I can only help telling you factors you could double check and tweak.
Edit 3: Thinking even some more, there should be a Rocket equation calculation to account for the weight of fuel for the retrothrusters to reduce the velocity on the hellpod. Additionally, taking into account the action of flaps and retrothrusters to reduce the Gs on impact you can afford to use lighter materials in both the cone and the hellpod walls. Also, you need to account for the insulation for the material, although you could just line it with Aerogel (which weights the same as air roughly) and your insulation issues are taken care of.
'real hellpod' in a sci fi game
@@Random-user22 what kind of person comes to a video about the math of a hellpod from a sci fi game and what bothers them is the "real hellpod" expression?
SUSTAINED 10 Gs is what pilots are trained for, so we could assume that during the slow down by the engines and flaps, the helldiver could experience 10 G optimally, but the actual Gs during impact can be higher since they're felt for a shorter time, ejections seats in fighter jets, for example, can make the pilots feel up to 30 Gs without dying, but being combat ready is a different story
I can tell your an engineer by how much you round and simplify during the process rather than at the end.
Doing everything in imperial units is CRAZY
Super Earth wouldn't use anything besides Freedom Units!
Doesn’t super earth use metric? It’s been a hot minute since I last played. Mostly because of server connection issues
@@quantumthedrago probably, but that is simply because the Ministry of War has been infiltrated by undemocratic, socalist, bot sympathizers.
@@quantumthedrago It certainly does for some of the stratagems (110mm rocket pods, 500kg bomb, 380/120mm artillery)
@@quantumthedrago if you ping something on the map the helldiver will call it out in meters
you can see the hellpod from the inside when it's not at use and you can also get the height comparison if you call stratagems next to you
If you manage to land a hellpod on the edge of an elevated platform (like a cliff) the side can stick out too so that can be used as a more accurate comparison to the helldiver.
Maybe ... make the tungsten nose cone hollow and then fill the tungsten nose cone with a metal that still has high heat resistance but crumples on impact like modern cars do.
It would still have penetration, it would have less mass and it would absorb some of the impact from the crumple effect.
As far as the hell diver not cooking in reentry ... spray or coat the puter layer of the pod in aerogel. Aerogel vittually weighs nothing and has extremely good thermal resistance.
Call space x for ideas on landing the thing , i aint no rocket scientist and i dont have a clue what sort of disposable rocket would be a good choice to slow down the pod just before impact.
Actually ... thinking about this more.
Maybe still use titanium in the nose cone but use a titanium honeycomb structure in the hollow nose cone. Tungsten is brittle.The nose cone would also contain more aerogel in the hollowed out sections of the titanium honeycomb and a on board navigation computer. The navigation computer in the nose cone would be insulated and protected by the areogel, the titanium and the tungsten from heat of reentry. The sensor for the onboard computer would be located on the rear of the pod to protect it from heat and have nearly direct line of sight to the ship that launched it so moyhership GPS can give guidance info to the pod to steer it and keep it on course.
I believe the pods would be produced entirely out of some weird tungsten carbide/titanium alloy and ceramic composites on the outside to possibly allow for a thinner wall, leading to a slightly lighter weight and lesser terminal velocity. With the thinner walls, I am also sure they could possibly store more fuel for the retro-burners, allowing them to cook longer and decrease the velocity much more over a longer period. Additionally, I'm sure there is some sort of internal shock absorption system/gels that reduce the G-forces on the occupant, as sci-fi as that may sound, but they already utilize similar materials in football padding and helmets to reduce concussive force from tackles and stuff.
I was also reading a lot of comments regarding the Super Destroyer's position during Hellpod deployment. The game tips even state that the Super Destroyer can only remain in "Low Orbit" for a limited time. I am sure they begin their descent as the Hellpods are prepped, so I feel it would also be safe to say that they wouldn't be dropping from an "outermost" orbital position, seeing as when you are on the ground (average loading screen time for me is anywhere between 20-30 seconds, do the math with terminal velocity) you can visibly see your destroyers lingering in the air.
I'm sure, being a little more realistic here, Hellpod drop locations would also be determined by some type of orbital geological scan. Send the Hellpods into a softer loamy soil or sandy areas than straight up bedrock and shale shelves. Notice how you have locations you CAN drop into, and locations (depicted with jagged rocky shapes) you CANNOT jump into.
I feel with enough funding, willing human participants, and coffee, I believe an actual, truly functional Hellpod isn't as far fetched as we might believe.
The main issue is finding the funding, the willing human participants, and a doctor that will unquestionably connect an espresso machine to me (and fellow Super Earth engineers) via IV tube.
For the reusable aluminum can there's the screw top aluminum beer can which I've seen for soda somewhere I think.
Highest g survived was ~200 so what you had could technically be survivable.
Though I think that was horizontal instead of vertical.
One interesting other thing that might help is a shock absorbing liquid inside the pod there was a similar gsuit idea that was used around ww2 but I don't think it really left the prototype stage.
Cool video hope this might be fodder for more like it.
Fair, however, I say we did this with glass bottles for decades where people would bring the bottles back to the store & they'd be sent back to the bottler to be washed & reused as part of the delivery process. We had reusable things then single use was found to be cheaper & easier for companies, so they switched to single use
The pod could have a compression system. so the HD is locked inot a frame inside the pod. and it hold them securely, but near the top of the pod. And on impact it's now has room to turn those high g's into lower g's by increasing time of deceleration. Also we really don't know what speed the pod is going on impact anyways, because the speed in game seems rather slow.
“I have a masters degree in engineering and I’m here to spread MANAGED DEMOCRACY” I’m pretty sure is what Raytheon engineers say to themselves each morning when they get up.
I feel like perhaps a better approach would be to calculate how long the engines actually burn for, assuming the hellpod hits the ground at a survivable speed, and then see if the acceleration is survivable.
Cool video, subbed.
Some kind of suspension system. Like after impact your human section is a couple feet lower in the pod amd the resulting compressed air could be used to eject you.
30 g's is the target? 30 g's of survivable 30 g's is not ready to fight
As a recent engineering graduate, There is a way to make a aluminium can reusable. Unfortunately it's not patentable as it is literally just a metal jar. Also when a hellpod glitched so that the tip was perfectly aligned with the ground some friends and I measured the hellpod to be about 3m tall (too tall to climb onto).
Lol
You could calculate the landing speed by hitting a helldiver on the ground with your hellpod and having a third helldiver with a horizontal view, if the helldiver is 6 feet you could calculate the time it takes for the pod to go from 6 ft of the helldiver to the ground and from that get the speed ( S= d.t)
honestly good idea lol
So it’s basically a pregnant bullet bill
Please never comment again
@@maybeiamepic2263 negative
This is something I’ve thought about since my very first game and I’m so glad I found this video
I have a theory that may explain why the helldiver doesn't turn into a pancake after the drop.
Let's talk about soft and dense bullets. Given the same velocity, mass and a condition of full non-penetration (a.k.a. the bullet stopped at the surface of the armor plate), the back part of the soft bullet will expirience less shock than the back part of the dense one. This fact was brought up when we were f#%king around with tracer rounds, but that's a whole another story. The reason is that a soft bullet spends up to 20% of its kinetic energy on the compression itself, while the dense bullet expiriences the shock with a whole volume, and that's why AP rounds have a tendency to shatter in small nearly identical pieces as a whole. The shockwave is evenly distributed around the whole bullet.
Hellpod is basically a big overengineered bullet, and if we take what I've said into account - it doesn't make sense to judge it as a steel monolith. If we make the frontal part of the hellpod soft and the back part dense (antipodal to what we do with actual bullets), the dense part with a helldiver in it will expirience less shock because the kinetic energy of the impact will be reduced thanks to the compression of the frontal part.
im not sure about the whole shock absorbing gel theory that ive seen in other comments since from my knowledge in hydraulics liquids arent compressible to any useful degree but my idea would have been pneumatic pistons under the hell diver that could be used to absorb the impact force in compression and then after wards use the pressure to extend the pistons and lift the hell diver out of the pod.
PS: im not an engineer, I used to work as a mecanic and my theory is only based on my limited knowledge of hydraulics and pneumatic systems.
Shock Absorbing Gel is mentioned in one of the ship module upgrades to add that to the sentry deployment hellpods.
A few interesting notes: The Hellpod needs a modular core to carry either troops or deployable strategems (Like sentries or special weapons). It also does not need to survive re-entry, as the hellpods are dropped from within the atmosphere at much below orbital velocities (A fact supported by the fact that the super destroyers are stationary above the AO). As such, the plasma in the loading screen is likely there for dramatic effect (rule of cool, what can I say).
In an upgrade there is mention of this gel that is used as a shock absorber. There likely is a cavity under the Helldiver's feet with the stuff.
Came here for a detailed explanation, not grand estimations. That aside, solid video. Made me wanna pursue engineering.
Another way to approach this: we know that the helldiver is basically guaranteed to survive the pods lithobraking maneuver and we know they use some sort of g force absorbing liquid in the eagle. So, assuming they use every g force survival technique at their disposal, that puts an upper limit on the forces the pod can experience on impact.
Bro did all that math to measure the height before realizing you can land your Hellpod in such a way that it reveals the full model
5 months ago... the good ol days of this game
I just started playing a few days ago and my favorite thing to do is when me or my friends get respawned we tag the biggest enemy nearby and see if we can kill it with our pod
I think the Monster cans with the twist-on-and-off caps are the only multi-use cans with a reliable setup, and they're three-part mechanisms (can, cap, and sealant puck in the cap)
The fact that you want the pod to hit the ground fast means you don’t have to worry about drag that much, so you can give it a nice bullet shape that will be stable at supersonic and subsonic speeds with a nice, smooth shockwave to ride on that won't make as much shock heating as modern day reentry capsules. Then you just need to slap some nice ablative coating on the tip and you're good
Gunpowder charge at the bottom with proximity fuse to both blow a hole in the surface of the planet for the hellpod to land in and slow down the hellpod.
The nose cone is likely actually a crush-zone to reduce impact force and absorb shock.
Thank you for explaining how super earth's soldiers safely land so their families can ease their mind.
big spring under the diver that helps him take the impact and how they pop back up
Three things you forgot are the shape of the hellpod is unstable, the nosecone could be coated in an ablative layer to deal with heat, and the hellpod could crumple the nosecone and use internal mechanisms to stretch out the deceleration time. If the hellpod was shaped more like NASA reentry capsules with a wide flat, but slightly rounded bottom, then it would have a lower terminal velocity, be more stable as it enters the atmosphere, and experience reduced heating because the flatter surface keeps the fiery part further away (because physics).
I have seen many ideas with shock absorbing springs that let the helldiver decelerate more slowly and while those are a great idea, I don't really see how they would work as hellpods seem pretty tightly designed, so no room for up/down movement. Some also suggest a breathable liquid the diver is suspended in but we never see any liquid being pushed out when the diver exits the pod. So either there is some fancy future anti-gravity technology at work or the actual g-compensating mechanisms are a lot more subtle. Maybe only the diver's lung is flooded through their helmet which could be connected to the pod with a tube we don't see as it detatches while the diver is still inside the pod? I might also just have misheard but was frame data used to calculate the g-forces on impact? Wouldn't it be easier to just use the pods height as a deceleration length and calculate from there?
Basically ICBM warhead but it loads with man and equipment
To not get squished they used squid magic technological techniques
This was most entertaining. Thank you for the lesson!
I always thought of it as being essentially a big bullet that can be loaded with supply or people.
the hellpods don't necessarily have to undergo re-entry since the ships they are launched from are hovering at a stationary point. The only reason they're going fast enough to cause plasma to form is cause they're shot out the bottom of the carrier. And because it looks cool ofc
We used to reuse soda containers… glass soda bottles used to be washed and reused at the factory. But it’s cheaper to just do single use and not pay for washing/collection facilities
I think they still do it in some European countries which is neat
If you land your pod on top of one of those pillboxes with the machine guns that the bots use, you can go inside, and your pod will be poking into the room so you can get a good look.
I probably should mention that super earth does possess kinetic reduction technology and used said technology to make a shield. My headcanon is they use that technology to protect the divers on impact
3:30 There are actually cheaper options than ceramic tiles that we have today, which work better than these tiles due to the one time use nature of the Hellpod: Ablative heat shielding. Instead of trying to absorb the heat, ablative heat shields actually turn to gas with reentry heat, the gas itself them absorbs the heat and is convected away into the atmosphere, thus sacrificing the shield to dissipate heat.
The shuttle doesnt use an ablative shield because it needs to be reused, but the Apollo program used them for their capsule reentries.
I would have assumed that the same mechanism that moves the Helldiver out the pod would also be some kind of g force shock absorber, kind of manipulating how the diver moves in contrast to the pod so they take less kinetic force on impact of the planet, it would be much more efficient than just a cool way to exit
Couldn’t we solve for the game’s depicted speed of landing by calculating how high up the pod is and how long it takes to fall?
Since the game came out I’ve had this exact question on my mind. And the only problem with Hellpods (along with ODST pods) is the impact when it lands. Realistically, there would most likely be a parachute to bring the pod to a near stop when it hits the ground.
Besides, hitting the ground at 100+Gs is for the rule of cool. If we as humanity ever got to the point in the far distant future where we needed space versions of paratroopers in the form of Orbital Drop Pods, I’m sure it would be close to what you came up with here. With a parachute for a safe landing.
Super destroyers don't seem to be in orbit really. To do that they'd need to be in planetsync orbit 40000 km away or more. They are just hovering several kilometers up firing thrusters to keep in the air
I am pretty sure that since the destroyers are above the ground (orbit) but they don't orbit but stay in one place with some high tech that means that the hellpod is falling towards the planet much more slower then the reentry v's we use today ^^
Thanks God for the nerds!, maybe the base where the helldiver is standing on has an impact absorption mechanism, or he has an harness to distribute the remaining impact on different points of the body to relieve the knees/ankles from the impact.
Orbital reentry heating is mostly radiative from the compression of the air, not friction. 👍
You could measure the impact velocity by throwing a strategem and landing the hellpod on it because you can see your distance from it. Then it is just displacement / deltatime from the video.
Hellpods slow down enough for them to dig not too deep into the ground. When you board the hellpod, you see your character dicending into the hellpod and after the drop, the character rises out from the hellpod's top side. So no pancake issues :D
In the ship upgrade modules there is liquid ventilation that allows eagle 1 to perform higher g maneuvers. That is what went wrong, you forgot to include that
As far as resolving the pancakification.... The same system that lifts the helldiver up to the surface could act as a shock absorber upon initial impact. Allow a few feet of travel to help lengthen the time it takes to stop.
The helldivers don’t turn to mush because their bones are simply made of titanium
Better acronym (that fits the video content, even) - Single Operative Drop Apparatus - SODA.
This feels like something that the Old game theory would do, also interesting video
Damn, you made me realize why the theory channels don't really feel like they used to, no math or applied sciences, just reading from some "study papers" it seems like, and then usually followed with some flawed experiments with no control group. It's really a shame, because there's no lack of content they can do these sorts of thought experiments with, I guess it was just too much work.
You can make better calculations of hellpod dimensions by throwing it on the roof of automaton bunker. It stops in the roof, and you can clearly see details of its hull
i think you forgot to account for the possibility that the pods are filled with breathable perfluorocarbons like the liquid-ventilated cockpits used for the eagles at enough of a pressure that the pods physically pop off the cap a second after impact like a tennis tube in an oven. said perfluorocarbons would help them absorb much more G-forces as they'd be cushioned by it and would also be able to actually breathe even with the increased G-strain. the divers are also probably on a gantry-fixed plate that shifts around by a good few inches and likely crumples another structure under them during the lithobreaking. plus you're forgetting that they get ejected straight down, pretty much, which shaves off a good chunk of the speed.
You forgot the armour and padding all that bubble wrap must help
You can easily see the entire hellpod if you land in some weird cliff area - the thing will stick out of rocks.
not considering a pneumatic cusion or fancy spring to increase the desceleration time for the helldiver, fer shame!
You could technically fudge the numbers up to the point of when the pod opens then! much nicer maths!
You should be able to hold the jump button to turn off the hellpod thrusters. It would make it so the hellpod cant be turned, it falls way faster and does triple the damage fir when you want to splat a big SOB and you have great aim
The reusable version of the soda can is the plastic bottle
could have figured out the final velocity seeing how many hellpods of distance it covers in a second when you call in reinforcements and used that for the rockets
A single use soda can?... Thats a bottle
There’s an offhand mention of the Helldiver being 7 feet tall at the end of training by General Brasch. Not sure if this intended purely as a joke but it is mentioned.
I think you misheard it
It actually took him this long to explain. Could’ve had it down in two minutes😎
What if the fuel is used to absorb some of the heating from re-entry? Most of the mass of the pod might also be fuel in tanks in the sides of the pringle can of democracy, so burning it while slowing down would dramatically increase the aerobraking effect once you are in the denser atmosphere close to ground?
I don’t know much about physics, but what if the hellpod had some kind of shock liquid inside that would take some of the g-force out for our Helldiver? Would that help with the survival of the Helldiver?
Not to be that guy but the heat from objects burning up isn’t generated by friction with the air, it’s generated by the drastically increasing pressure as the object dives deeper into the air
I think the re-usable can is called a bottle :P

Actually, thinking about the hellpod dropping in and steering, how the hell do they see where theyre steering while in the hellpod?
a better gauge for the speed would be to look at a hellpod dropping in, so how long does it take for the hellpod to travel the its own length when the rockets are on? it will be wayyy slower
Taking the Cd of a bullet would have been more accurate than the cone. Because the cone is not the only thing that affects Cd the whole body does and the hell pod is shaped like a bullet.
That's why aerodynamically smooth cars don't just call it a day by designing a aerodynamic front end, they have to design the whole body.
1.0 Hellpod stuck together by ???. 1.0001 Hellpod stuck together by super glue!
I have a screen shot of the hellpod side were the loading screen glitched out and the fire went away that measurements could be done on
The reason they survive isnt "its a videogame" its "they have futuristic shock absorbing materials and mechanisms"
I heard that in the original helldivers theres a story of the first hellpod prototypes killing their users because of what you stated
Orbital entry is not the first problem, is it? Getting shot out of the launchtube and not transform its contents to mush seems to be the first problem. Right?
When calculating the weight of the nose cone, you said the diameter and height were about equal, but when calculating the volume you took put in 2.75 (the radius) for the height as well when height should be 5.5 (the diameter), right?
A reusable can is a metal jar
My only question is if it’s slows down to a quarter of its original speed would it even go into the ground the full length
You know you can get pics of the hellpods where no fires around them right?
Firstly, the question would be: Would a shuttle who's purpose is to plunge straight into the surface of a planet, excluding other factors like rocks and whatnot, just pure planet substrate if it's even possible for someone to withstand? If not, then the hell-pod idea is entirely not possible in the exact way which it is portrayed and thus a single-use deployment of a single soldier should instead be something else. The purpose of this should be rapid deployment whilst maintaining no-change in the integrity of the soldier's vitals.
The hell-pod idea will only be viable if it was said that Helldivers had the appropriate augmentations to withstand such force, a.k.a them being not fully human, or rather "super" humans (get it?)
Other than that, the pelican would be the only form of transport from planet to orbit, but even that is another thing to solve for how a VTOL like aircraft is able to effortlessly fly from surface to orbit.
Got an idea for the acronym… how about Single Occupant Exoatmospheric Insertion Vehicle ;D
