Don't you press that G?
I managed a sharp G.
Hahaha lol 😂
@Ned Kelly No due to design limitations, he was un able to 'sustain' it due to energy decay. I myself employed a electric guitar and a hi mu amplifier.Not only was I able to sustain full 'G' but as well employing the floating Floyd 'stick' equipped on the guitar I was able to perform flawless maneuvers. Dive bombing and immediately recovering and then pulling back on the 'stick' to reach the stratosphere! 'Blacking out' only when my angry wife 'pulled the plug' and 'crashed'

Stuka pilots were dope at negative G's
Man avatar state was a reference to avatar the last airbender
Yea i kept repeating it
Coming from a background in aerospace engineering, this video is excellent! Factually correct and easy to understand. Would love it if some of my old professors had showed us something like this. Props for even using the "standard" body-fixed axis orientation.
"I Call upon the ancestors for knowledge of combating G-Forces" *ancestors* "Uhhhhhhh, hell if I know"
Stuka pilots were dope at negative G's
Negative G's are horrible. Got to go on a formation flight flown by retired f-16 pilots (in a blackshape prime, about 50 steps down from an f-16).
The +4G was fine, however anytime the slightest bit of negative G hit i felt like puking.
@@ric84 cuz the blood goes up to your brain instead of your legs
@@mahrezkh1894 Nah the negative Gs weren't intense enough to force any considerable amount of blood to my head as far as i experienced, it just made your stomach twist and turn like nobody's buisiness.
Imagine going down in an elevator times 50.
Stukas flew at very low speeds, like 200-300km/h so the initial drop wasn't supposed to be that bad. Imagine the second drop of a roller coaster(not the first where you hardly have any speed)
Imagine a jet dive bomber
Plane actually needs 3rd very important thing. Strong enough controls to combat the air in said high speed. Doesn't matter how strong your wings and structure of plane in general is, if it can't move surfaces in order to make drastic movement changes in high speed.
Rentta planes used cables and leverage directly for a long time, Then direct hydraulic controls, and eventually ‘fly by wire’ (electrical wire, not cables) meaning a computer was involved. All of these were to allow higher G and more precision control feedback than humans could provide.
*nervous zero noises*
Hydraulic actuators are nothing new and have been around for a century. Important sure, special they are not.
@@MusicBent Minor tidbit regarding fly-by-wire, FBW aircraft still use hydraulics; each empennage has its own hydraulic device and they are electrically managed by a computer.
@@jhk8396 correct! Another cool thing about fly by wire is how it made unstable designs feasible!
I have followed your channel for a couple of years now and I just wanted to leave a short thank you for the videos you upload. I am no "Engineer" but I like to think I am rather mechanically minded and i really enjoy the detail and effort you put into these videos.
Again. Thank you.
16:24 I love how when you talk about the wing getting less efficient you show that plane sliding off a carrier 😂

A pilot dying. Yeah fucking hilarious.
@@MrComputerCoder We don't know for sure that anyone died that day
@@limiv5272 Yeah it's hard to tell if a pilot died while he misses his landing, slides across the deck, and drops in front of a Carrier moving where he just landed in the water. Really fucking hard to tell if he died or not.

We definitly need a video about thrust vectoring and it's use in dogfight
av8b and f35 eh ?
but risk of stalling is too high when in a dogfight
He's talking about the f22's thrust vectoring. Not the f35 and av8b
@@chikoopandya isnt the the same principle ? be it engine nozzle swaying or duct redirection or panels closing in (same as revers on the viggens)
Trust vectoring is rarely used in a dogfight. It's most useful purpose is for engine efficiency in super cruise, at least that's what the engineers have said. Pilots may use it completely differently in a pinch! In a dog fight you typically want to keep your energy as high as possible, which means not slowing down. But thrust vectoring can be used for some radical maneuvers. But typically those are very dangerous and will usually get you killed by whoever is shooting at you because your speed just drops too low.
Again these are generalizations so there's always lots of exceptions to the rules. For example, maybe you need to just get your nose around real fast on somebody so thrust vectoring may help with that, but modern missiles can shoot off bore with great efficiency so often that's not necessary. I guess it could be used when a gun fight.
It would be great to hear from a modern pilot that uses thrust vectoring regularly!
I mean nowadays dogfight are pretty much useless due to the fact high tech missiles exist. They can outperform and out-track every one so fights usually happen kilometers away from one another. The only area where having a gun is even somewhat useful is in CAS roles (god bless the titanium bathtub) but it is mostly useful against people without effective AA (which still represent most of today's targets) and lose effectiveness when you are talking about fighting against missiles. To be fair I am somewhat interested to know why there isn't more long range missile platforms that shoot cruise missiles and araams from 40 km away. I mean at this point shooting the missile down with another missile is probably more effective than trying to dodge it.
AF Pilot here. The airspeed on the Heads-Up Display is in knots, not MPH. And it's "indicated airpseed"; so at 16,000ft your groundspeed is a lot higher, because the gauge is in thinner air than on the ground. Great video! Sorry you got sick!
The highest G force I’ve ever experienced was the time I fell asleep while driving and impacted a retaining wall at 80mph, I was 6’7 260lbs at the time so no idea how much force exactly.
Jesus
I'm assuming you don't mean at 90 degrees, because just off the top of my head I don't think you'd likely, if at all, survive that. At some point the large aorta rips loose from the heart, as I understand it, and that is the limiting acceleration/jerk limit.

"This is not a scenario any animal in the past 4.5 billion years of evolution on Earth has experienced."
Birds?
Birds ain't shit dog. Flappy fucks
If you know any bird that flies at transonic speeds
A bird doesn't have enough weight to be pulling that many G's
Yeah, quite an exaggeration there. Just to make sure, I did a quick google search, and there's tons of articles talking about birds rutinely experiencing G forces greater that those experienced by humans in modern jets.
@@Luchoedge Yeah, I heard the line and was like "I wonder how many Gs birds pull" and ended up seeing way higher numbers than humans can tolerate.
At 16:24 That jet be like, "They see me rollin, they hatin..."
Jealous! Great video :)
Regarding the derivation of equations to calculate wing loading when in turns; in straight and level steady turns, the wing loading due to the angle of bank can be calculated by g=1/cos(theta), the increase in stall speed is V(s)=sqrt(1/cos(theta)). (where theta is the angle of bank).
G-suits were used by the US in their P-51 and P-47 fighters from the later months of 1944 onwards, I don't think they ever became common use amongst the British in WWII - although I was unaware of them being used by Seafire pilots!
My uncle Roy Allen was the lead mechanic for the Thunderbirds for several years after the Air Force told him he had to retire (mostly because they didn't want to pay his severance package if he stayed any longer). He went on to work on the development of the F-35. I watch this channel a lot. I think it's pretty cool that you've been even closer to those planes than I have (close enough to touch one), and I own one of the the ground crew insignia pins. Well done!
I am pretty curious for the stream.
My favorite part 1:53
"During that vertical climb I reached about 4.8Gs
There is literally no scenario in human evolution that simulates the forces your body feels when a fighter jet decides it's time to change direction.
I felt like my brain was being rewired as it happened, like my brain was going to go into the avatar state and ask my ancestors for advice on how deal with this shit but not a single one of them even knew what an F-16 was. The closest any one of them even got to this level of G was when my grand pappy stood up too fast whilst digging potatoes in 1932 and got a little lightheaded "
Was it worth typing all that for 26 likes?
Getting to fly with either the Thunderbird's or Blue Angels is definitely on the top of my bucket list. Though I'm sure my health would probably immediately disqualify me from even doing that!
We Demand More of Such Video
Tzwac dastag I’ve never seen ground stabilized 360 footage from a jet like that. Super cool if we got the raw footage without music or narration
It is amazing to watch planes fly... but what really pulls me in, is watching the surfaces doing their jobs, like the leading edge slats on the F-16 dropping down as the plane takes to the air, and slowly raise up.... it is like watching the suspension on a car, it just....it seems awesome to me to watch these things working....

Hey real engineering, I have a possible request. I love seeing your videos and the sheer quality and work being put into each one, but we never see the behind the scenes on how the video was made.

3:35 That view is badass. So very cool
FH Phantom was actually the first American jet powered carrier based fighter (which would later become the F2H)
I am actually very impressed that your airspeed barely changed while you were pulling that 4.6Gs vertically.
F-16 has a Thrust to Weight Ratio of .9-1. Given enough air in the intake, it would be able to hover hypothetically.
3.5 G's is the most i've ever felt on Lagoon Amusement Park's "Cannibal" coaster. Even that will knock you out if you don't brace for it. The fact that anyone, suit or not, can withstand 9 G's is insane.
Hey, I've got a lithograph of the huge mural (13:45) at Nellis AFB. Home of the Thunderbirds. Awesome painting. Got it back in '91 during my AF ROTC days.
Whenever i do a turn in Warthunder:OVERLOAD 9G LOST CONTROL
Me when i see nerdy boy from western Ireland getting his share of Gs: thats one unlucky chap suffering for the name of science
What if someone made a choker that activate when you exceed your pilots g tolerance in war thunder? Sounds like what michael reeves would do
I was thinking of that when watching him flying. I am talking to Jeff rev
@Eric Hung Oh yes
I've spend some years in design of rollercoasters, forces are real. We consider the heart line during the ride. Decades ago was the reference coordinate-system the main axle of chassis. 4,5G in vertical direction was allowed, but nobody considered the additional acceleration at the heart. It caused 5,5G accelaration in passengers heart. This was overkill. Today, we considering the heart line. The heart line gives the path and any curves of the structure will be given. 5G vertical, 1,5G horizontal and 2G side accelaration is "ordinary".
Great vid!
I was freaking out from about 2 Gs in a glider, and this guy just takes 4.5 like a champ. I must say, you were built to be a pilot
modulus of elasticity
The modulus of elasticity equation is used only under conditions of elastic deformation from compression or tension. The modulus of elasticity is simply stress divided by strain: E = σ / ε with units of pascals (Pa), newtons per square meter (N/m2) or newtons per square millimeter (N/mm2).
6:43 "In order to rack up high G's in the air, the plane needs to have two things:
1: A powerful engine capable of reaching a high airspeed"
As a glider-pilot I feel offended. :D
My plane has no engine at all and I have surely had pulled some high G's before. Only drawback is, that high G's (or rather the manouvers that cause them) cost a lot of kinetic energy, which a glider can only obtain with potential energy aka height.
So pulling high G's equals loosing a lot of hard earned altitude.
Anyway keep up the nice work! As an civil engineer and technical interested person myself I am realy enjoying your videos!
Your definition of “high G” is clearly not the same, lol...60 degree banks in a 172 at 100 knots only produce about 1.5 Gs, so I highly doubt that even those kinds of loads could be experienced in a glider.
That’s literally what he stated in the video. WW1 pilots had to limit their high G maneuvers to short bursts if they wanted to stay flying. Your situation as a glider pilot is even worse
@@ozzman1997 please don't just assume things. gliders are light and have a big wingspan which is able to generate quite some forces, so combined with the low weight quite some Gs. There are glider aerobatics as well by the way. Gliders probably can't create the same forces as a fighter jet, but those 4.5G from this video are definitely possible. EDIT: Actually, here a guy passes out in a glider, definitely more than 1.5G, a comment of the guy states "around 5Gs": ruclips.net/video/waM_fE_YEyk/видео.html
@@ozzman1997 , it's relatively easy to get to 3-4g in a glider, and even on a paraglider. A 172 is a fine plane, but it's not a very capable once you're doing anything exciting ─ although I suppose there are some that have been modified for acro.
@@ozzman1997 A 60 degree level bank is exactly 2G, regardless of plane or speed. If it is capable of pulling a level 60 degree turn - it is doing 2G.
God I wish I could've become a combat pilot, seems like the best job in the world to me. Not after breaking my left arm 5 times sadly, got rejected 😅
Anyway great video, keep up the good work.
Mensh did you break it 5 times or in 5 places?
Four times in one place near the wrest and one time up the arm. I was a very 'energetic' kid so I was REALLY accident-prone.
Excellent video, thanks for explaining, didn't understand a word of what you explained but still enjoyed it.

@@chrishall2594 that's fine, there's not an aircraft currently built that can fly with the precision and accuracy of a bird, bat or insect, especially not at the weight/strength ratio or energy efficiency. Apples and oranges.

Chris Hall peregrine falcon can nosedive around 242 mph.
Dont forget about woodpeckers as well, they've evolved to withstand hundreds of G's repeatedly
Your videos are so informative , thanks a lot.
Riding a moderate intensity roller coaster is about as intense of a G force I've ever experienced, and I'm happy to keep it that way.
Most pedantic of corrections: G is the gravitational constant, what you're talking about is g. Awesome video, glad you're getting the payoff you deserve for the work you've put into this channel!
Thank god i'm not feeling this kind of body stress in Ace Combat.
Play War Thunder m8
Eww... Ace Combat
Fun fact: Every game in the Ace Combat series has you pulling ridiculously unrealistic Gs, except Ace Combat 3. AC3's physics are more akin to a simulator, and the lower level planes are about as maneuverable as modern fighter jets, with the exception of more powerful engines. The later planes do get maneuverability which is much more extreme, achieving G forces outside the range the human body can tolerate, but even then, it's not inaccurate. The current fighter jets can handle much higher than 9 Gs, but are limited because of the pilots, and in AC3, the cockpit has you laying down in the plane, instead of sitting, which is a position in which the human body can tolerate G forces much easier.
+G maneuvers: In future aircraft. Piolets may sit in a rotating sphere and control the aircraft via heads up display only.
the video is masterpiece!!!
It covers

"somehow this nerdy boy go to fly thunderbirds"... hmm could it be because you present the military in a 'cool' way
I mean yes. There is a reason I get invited. I have my morals though. I cancelled a huge contract with the RAF this year because their agent (I stress it was their agent, not the RAF) wanted me to promote the RAF as a place to work directly. No thanks. I'm not about that.
@@RealEngineering fair play mate, I'm glad it's something you've given some thought to
The F-16 has always been one of my most favorite planes. In addition to being so maneuverable, it just looks So. Damn. SEXY. As much as I love the capabilities and looks of the Raptor, the Falcon is still, in my mind, the sexiest looking plane there is.
For me it's the Gripen from Saab
For me I favor the F 22 or F 14
F-15 & MiG-29 all the way boiz, but taste in planes is subjective :P

Centrifugal force doesn’t exist. It is really inertia! Mv^2/r gives you centripetal force, which points to the center of the circle👍
Wrong
Real Engineering
Wait can you please explain why? I’m genuinely trying to understand. Thanks!
@@nickh7902
You are right!
The airplane wings produce the real force, where the radial component accelerates the airplane against its inertial mass . The reaction to it is commonly but inaccurately called
centrifugal 'force'.
Like you said the magnitude of this component is
M×v^2/r.
where r is the instantaneous radius of curvature of the trajectory.
The vertical component M×g supports the airplane's weight on a level turn.
The wing lift is
L=√[(M×v^2
)^2 + (M×g)^2]
In summary you are correct, his comment is wrong.
Also incorrect @ 8:18 is the shear diagram, which is not linear, unless the lift distribution would be constant, which it never is on a wing.
Disappointing is the sloppy physics by Real Engineering.
Why does an airplane survive a g-load?
Because above the maneuvering speed the angle of attack is limited such that the structural design enveloppe is not violated. Every airplane wing prior to certification is tested in a rig to limit load to ensure it can take the design load multiplied by the safety factor, usually 1.5 before destruction.
The limit loads are defined by regulation in civilian A/C
That is some absolutely breathtaking footage..
I loved this video 😅a real account of what's like to take those g's? Priceless! And I didn't have to spew up to learn it!
What about Low-G maneuvers?
You mean negative G maneuvers?
Regular flight or high negative g?
You mean 0 G manouvers?
That's basically like an elevator accelerating downwards
In addition to what Comrade Stalin said, fighter jets like the F 16 generally will not commit, such manuvers because they are not designed for any high negative g. Also negative g reduces the ability of the pilot to aquire, target and shoot down an enemy fighter.
"This is an experience only the genius and stupidity of man could facilitate"
I hate to be a nit picker but the caption for the lift on a wing for the aircraft says Lockheed F-16, when it was developed and produced by General Dynamics. Otherwise great video!!! Love this channel and every video is watched multiple times over!
Funny thing, the sudden acceleration of a catapult launch feels like the aircraft is nosing up, and so a lot of naval aviators pushed forward to correct and went into the water right off the bow of the ship.
Ouch that's embarrassing
