nasa has great knoledge in unbalanced rockets, considering the shuttle as a mess to balance (huge outside tank, solid booster, wings, off center nozze, off center cargo)
Just to put it out there for anyone still watching this :P.. Procedural parts SRBs do now have a setting to adjust the nozzle's tilt. So you can actually build an SRB, and mess with the tilt of the nozzle to counteract it's offset thrust.
Actually a dual-engined Centaur has flown, just not on an Atlas V. Centaur was originally designed with two RL-10s in the 60's. Performance improvements meant that one could be deleted, though two is still an option.
@@imagineaworld oh yeah, if you know whats drifting is it automaticly makes you a forza player got it. and drifting is power sliding becuase just look at it you literally just slide with power on the wheels and the 'wheel'
I just watched the ULA launch footage and came here looking for an explaination. Luckily, this was at the top of your channel! This is why the world loves you, Scott.
3:32 Scott:"...You're gonna see right away, it' starts going sideways - Whole thing is essentially is power-sliding off the launch pad like a boss." Best quote ever :D
Lockheed Martin engineers : so after consulting with an expert, it appears that "adding more boosters" would solve all our problems Scott : Did I tell them about the symmetry button ? Oh well, they'll figure it out
Hi Scott, I've added nozzle deflection on ProceduralSRBs! The plugin should be updated soon. I was actually adding another feature in the ProceduralPart plugin while listening to your video. I've added polyhedral (3 to 12 sides), mk2 & mk3 shapes and I've also managed to code an adapter part that support different shapes and sizes (like hexagon to mk2 for example). Theses ares mostly finished and should come soon.
I was at the ULA Ground Station in Denver for a launch viewing of OSIRIS-rEX. I asked them this very same question about the 441 configuration! It was very interesting to get to talk to the engineers about this.
Well, I'm not Scott, but I can suggest a couple things. 1) Keep them as small as possible. See how tiny you can make the probe and still be able to cram all the necessary bits on in a plausible manner. 2) Look at real probes for inspiration. A personal favorite of mine is Luna 9. There's something amusing about a weird lumpy probe that shoots a big egg into the sky. 3) Try AIES and DMagic Orbital science; they both add nice probe bits and science experiments respectively.
Thank you for the explanation Scott! I'm not a total rocket noob, but have been wondering about the strange Atlas V SRB configurations for some time and seeing OSIRIS-REX being launched on a 411 just brought the question up again. :)
Great video! I would lead off why the SRB's are offset at the beginning of the video instead of the end. Pose the challenge at the beginning so we can all be stupified until we get shown this awesome workaround and how it works. Love these explanation vids. Short and sweet.
Thanks Scott, Nasa TV mentioned 411 configuration twice already since I started watching the launch coverage - kinda nice to know what they mean. Now if only they would put up altitude in meters and not feet - fingers crossed :)
"Power sliding off the launch pad like a boss" lmao. nice one Scott. Great video otherwise too! The way I tried this before watching your video was just to reduce the SRB throttle to 50% & the regular engines do just fine too - the SRB almost lasted as long as the 1st stage too :)
There are two mods that will get you something much closer to what the Atlas 411 really looks like. KW Rocketry has an SRB that looks just like the ones used on the Atlas. Its nozzle is angled outward but I'm not sure if it's enough. Ven's Stock Revamp adds an engine that looks a lot like the RD-180. It has two nozzles and a 4 degree vector range.
It also makes more sence from a manufacturing perspective all these configurations can be mounted to the same 5 mounting points. If you would try to space them out evenly only the 2 and 4 config could use more than one common mounting point.
It's cool watching this 3 years later when they are currently mapping out where OSIRIS-REx will be making its touchdown on Bennu. Turns out Bennu is basically a giant pile of rubble so it's gonna be tricky
I think it would also have been useful to mention that the X2X and X4X versions are asymmetrical because they use positions from the X5X setup, as all setups do. This means they don't need different mounting points depending on the version, it just means they need some and don't need others.
Hi Scott! I think that you should have rotated the two vector engines and not the solid booster to compensate the slide . The problem is that the vector engines ignite at 0 vectoring and that gives a little side push from the solid booster. If you rotate the vector engines that would compensate the side push from the booster right at the ignition. Regards!
Thanks as always for the video Scott. Sorry if it's off topic for the video, but in one of your live streams you mentioned you learned a lot of what you talk about from reading on your own and watching documentaries. Do you have a list of some of your favorite reads somewhere? I'm always looking for great space/physics/astronomy books and shows, and if you have some suggestions I'd love to see. Thanks!
another thing you could do is turn down the thrust limiter on the solid rocket so it pushes less and the engine can compensate and it burns longer like you said
The SRBs in reality also have an inward thrust vector built into them, so that helps as well. It was weird looking to watch! But of course the space shuttle was asymmetrical too.
Thanks for the informative video. However, I think I read there are other versions in the planning with the DEC (dual engine) version of the Centaur upper stage. For the SNC DreamChaser spaceplane I guess, or Boeing CST-100. That would add more possible versions, the bigger possibly being 552 ! But again, what number would account for the fairing, or lack thereof, when launching a Dreamchaser ?!
Hi Scott. I really want to hear about your opinion about the EmDrive and the recent passing of peer review of NASA's version of the engine. Do you have any plans on making a video covering this subject in the foreseeable future?
@Scott Manley This doesn't make sense. Why didn't they build it like 2srb on left vs 2srbs on right instead of 3vs2? In my configuration they would still be able to put 1vs1 but this time symmetrically, with 1vs0 it would be the same situation as here. But let's compare 2vs3 vs 2vs2 (so many vs's... :) Off course the 3srb have more thrust than 2 but as you noticed to compensate they need to use main sail with bigger vectoring and/or swivel the nozzles of srbs a bit. BUT doesn't the vectoring/swiveling mean that the part of the thrust is redirected to move the rocket horizontally? Isn't that redirected thrust wasted? We don't want the rocket to travel horizontally (on that low altitude). Especially that it means carrying extra srb (extra weight!) just to make swivel it and its neighbours enough to lower their vertical thrust to equal thrust of 2 opposite srbs. (Not mentioning the unequal air resistance and other disadvantages..)
So why did they fixed the mountpoints to be 3vs2 when (if my thinking is correct) the 3vs2 configuration has the same vertical thrust (due to the wasted horizontal) as 2vs2. They could fix the mountpoints to be symmetrical 2vs2. Pros: - the same vertical thrust as 3vs2 - not carrying extra srb weight - no asymmetrical configuration - less complicated configuration (air resistance etc...) Cons: - ??? There must be some. I'm sure that NASA didn't just mount the extra srb for fun :) ... Or did they? Maybe they have more in common with Kerbals than we thought?
The 3v2 is more thrust than the 2v2. The horizontal component of thrust is a small percentage of the total thrust (5.2% to be precise is the 3 deg cant is accurate).
You're making the wasted thrust a way bigger issue than it really is. The nozzles on SRMs are canted by about 3°, and the RD-180 can gimbal by 8°. If you look at the vertical thrust components (just multiply by the cosine) you're only losing 0.14% thrust on the booster and still less than a percent on the main engine, even if the nozzles were fully deflected.
In real life the variants of the atlas V has it's boosters offset because the weight on the inside of the main section is not centered as well as the external engineering. Those fuel tanks aren't just neutrally weighted cans of fuel, they have a lot of internal works as well to handle that fuel and keep it safe when it's flowing.
Did you say a single engine with two nozzles? Wondering why, knowing the pressure rating of a vessel is inverse to its diameter. Sounds like if you needed two nozzles your combustion chamber would be very big. I am sure there are a lot of other factors to consider.
Scott can you make a video or help me with this problem I'm having with re entering a space plane. when ever I try to re enter it gains speed from gravity and it goes above the part heat which is 1400m/s for alot of stuff and it gets destroyed before I can slow it down. if you could tell me the best angle to re enter or how to slow my self down that would help alot! (can you do it with base game parts only because I have no mods)(I'm asking you because you know sooooo much and your a great guy)(thanks if you respond!!!)
The important thing with aerodynamic reentrys is to use your wings to drop to an altitude where you get the most braking without overheating and then stay at that height. Not every glider can manage it and honestly there's a lot of guesswork involved in finding the reentry trajectory that works for your design.
Break-burning, Airbrakes, Aero breaking. To be fair, the easiest way I found is using tons of airbrakes, which will act like a massive parachute and slow you down rapidly on decent. You could then also have small thrusters in the nose that help slow you down even more.
That's necessary to avoid turning the astronauts into strawberry jam, or at least making them very uncomfortable. Satellites on the other hand don't care so much. The RL-10 upper stage engines are old tech and ludicrously expensive to make, so you want to use as few as possible. So normally you fly mostly straight up and then do a big dogleg into orbit for satellites. Humans are a bit too squishy for that, so you have to go sideways earlier on the core stage but that means you need more upper stage performance.
Actually... I would think there really is no advantage to having an asymmetrical rocket except when you are dealing with a main hull that already has asymmetrical bits on the outside of it. Of course there's the monetary advantage if you can pull off the adjustments needed and don't need to get the payload into a really high orbit. If all you need is a little boost at the initial launch stage, then a single booster would offer you exactly what you need without requiring a lot of calculations regarding length of burn and whatnot. You'd waste less resources on the other SRB carrying less than it's optimal fuel source.
If the problem was stuff on the first stage getting in the way, why didn't they space the SRB(s) further out from the core so they wouldn't overlap the stuff sticking off the core, using something like KSP's TT-70?
Today's APOD shows the OSIRIS REX liftoff. I noticed the exhaust trails was slanted. Was that because the Atlas is moving laterally or because of the vectored thrust (both?)
thank you for saying 'regardless'. proper use of the language. I'm really tired of people saying irregardles (double negative). oh and as always I love your videos. just sub'd Cheers
nasa has great knoledge in unbalanced rockets, considering the shuttle as a mess to balance (huge outside tank, solid booster, wings, off center nozze, off center cargo)
Yep, it's just a thrust vectoring problem that is hard to solve in KSP given the limitations of the build system.

Excellent video Scott! I'm always impressed by your ability to disseminate technical info.
Crazy to live in a time where the mission this video discusses, Osiris REX, had already been completed.
Your voice is so soothing to listen to, couple that with the technical amazingness of KSP and its probably my favourite thing ever.
Huh. Well the asymmetry makes sense now. I guess it's easier to just use thrust vectoring than it is to redesign the whole rocket.
I was at the ULA Ground Station in Denver for a launch viewing of OSIRIS-rEX. I asked them this very same question about the 441 configuration! It was very interesting to get to talk to the engineers about this.
This reminds me of the shuttle engines looking like they're locked offset to the boosters on launch giving a bit of a side ways drag.
Scott, could you please do a video on making probes or satellites in KSP look aesthetically better.
And if you do please include the mods you use to make them look better
Well, I'm not Scott, but I can suggest a couple things.

Project "Peg Leg". Best name for a rocket EVER.
at 7:33 there are actually 3 on one side, one is clipping into the other.
Yeah, and there was some clever camera rotation to try and hide that. It failed of course. We're way too quick to be fooled by camera rotations.
I think that was an error when building it
Thank Godfor you posting, I thought I was insane.
Probably forgot symmetry on.
The real one actually has two SRBs clipping into each other. The MAN just doesn't want you to know about it.
Use the SSTU mod, it has what you are looking for in it's SRBs.

+bagins82 yes the lateral thrust is wasted. There is a 2vs2 config - the 541. But the mount points are fixed so it's still asymmetrical
So why did they fixed the mountpoints to be 3vs2 when (if my thinking is correct) the 3vs2 configuration has the same vertical thrust (due to the wasted horizontal) as 2vs2. They could fix the mountpoints to be symmetrical 2vs2.
Pros:
- the same vertical thrust as 3vs2

There must be some. I'm sure that NASA didn't just mount the extra srb for fun :)

Hunting worse than the LEM ascent stage. Gotta love it!
Now, I wonder if there's a mod for offset SRB nozzles?
I"m thinking N Korea should consider allowing youtube access to their country.
Scott! love your videos!! I wondered if you offered an introduction to making space stations, I use the console version
In real life the variants of the atlas V has it's boosters offset because the weight on the inside of the main section is not centered as well as the external engineering.

"And besides, it works in Kerbal space program"

In the 5 meter version, the centaur upper stage is inside the fairing of the rocket,not exposed.

Yo! Scott love the videos! Will KSP ever have a steam workshop? If it will, when?
I dont think KSP will have a steam workshop since that would be just unfair to those who didnt buy trough steam.
The other reason for the booster configuration is it allows any number of boosters on the same core, with no specific preparation
To make it easier to fly you could try using the soft controls (I think it's capslock by default). It helps me, at least.
I actually got to see Osirus Rex while it was being built at Lockheed Martin.. Got to wear the fancy white suit and everything.
