Iron Man's arc reactor is based on the Tesseract. The blue cube in Captain America 1 and Avengers 1. Tony's dad was able to study it and was able to theorize the energy but he wasn't able to recreate it because he was "limited by the technology of my time"

[@bellatorbacon5861]

I'm pretty sure that is the new core that Tony made in Iron Man 2, because that was when the recording was shown and Tony found the structure of the element the core is made of (as you said, it's based off of the tesseract or the space stone. But not the previous ones because Tony didn't watch the recordings yet, and he used palladium for the cores.

[@endosym5023]

@@bellatorbacon5861 Howard was able to partially recreate the energy of the tesseract, as the giant arc reactor proved it, but because he was limited by the technology of his time, it was imperfect and unfinished. So that's why he switched to palladium, cuz the prototype arc reactor was unable to keep up with the energy demand of the electromagnet and suit. But because he found his father's notes and the blueprint he laid out in the expo design, he was able to complete Howard's unfinished work and make badassium

7:59 It is said in the film that his armor is made of an alloy of gold and titanium because "it is more solid". Later in the scientific community, some had fun checking that out. And the film (luckily) was right; the gold-titanium alloy is much stronger (but also much more expensive) than titanium alone. So it's not surprising I guess?

The Arc Reactor is supposed to be a type of theorized energy source called an 'induced decay reactor'. The premise was that you could bombard an isotope with some form of radiation, in this case I believe it is supposed to be a platinum-paladium alloy bombarded by electrons, to artificially induce a nuclear decay and capture the resulting particle as power. The platinum or paladium isotope decay trees do include an electron emission, and that particular isotopic decay induction was theorized at the time to be possible with a magnetic field. That was why they put in the scene of the Arc Reactor first needing to be kick started by an electrical power source before it became self-sustaining. I think the theory was later disproven with experimental testing, but the idea was beyond cutting edge back in the day.

[@AviationAustin]

That's impressive comic knowledge! Thanks for the description!

[@funveeable]

The exhaust that comes out of Iron Man jets is plasma, and it leaves at around light speed. The momentum of low mass but extremely fast gas give him the propulsion needed to fly. The smoke stream is the plasma igniting the atmosphere. This kind of thruster is only possible because the Ark reactor has the power of a nuclear powerplant behind it to make this plasma. Impractical engine for anything that doesn't have an Ark reactor.

[@daniellucas2968]

Thanks for this explanation. I had thought that it was supposed to be some sort of miniaturized Tokamak reactor, but that makes a lot more sense (even if the theory ultimately failed).

There are some ridiculous scenes though. For example, when Tony escapes from the terrorist camp in the prototype ironman suit that he cobbled together. When he sails through the air and lands in the desert he comes to such a sudden stop in the desert sand that even if the suit didn't come apart (which it did), he'd be little more than a splattered bag of goo. There's just on way he'd survive the g-loading of hitting the desert sand from so high up. And there are plenty of other nit picks. But it's a movie. It's for fun. And as an engineer myself I really love the Ironman movies.

I know this is an old video, but wanted to add a bit of detail/correction to the ejection seat claims. I used to work on GRU-7 and GRU-8 ejection seats. You are 100% correct that they are designed to work fully automated. However, they are also designed with barometers and DO NOT deploy the parachute until the seat has dropped below 8k feet. We dont want pilots freezing so we dont want to deploy a chute too early. The drogue chute will deploy right away to keep the seat stable as it falls (so its not doing flips and twists the whole way down) which then will pull the main chute and release the pilot once the barometer meets the required altitude.

[@AviationAustin]

That's awesome. Thanks for your knowledge and insight! I always welcome kind correction!

One particular bit of science added in the Iron Man movies was the use of his hand repulsors as thrusters to help hold a parallel plane to the ground. In the Iron Man comics I grew up reading as a child, his boots were the main and only form of thrust and direction. It would be nearly impossible for Stark to hold that form while in flight.

Of course there are moments where things are a bit more suspended in disbelief. But most of it is grounded in reality. Like space travel and skip jumping.

Magic and mythical creatures are on that edge of disbelief, though if Thanos is real and is part celestial then a dragon like creature makes total sense.

i was an ejection seat mechanic in the Navy. Ejection seats are never researched by movie makers. { ex: Goose would NOT have died ).

Typically expelled through the urine or fecal matter. Did you know that certain cows expel actual gold out of their body through urine? People do the same thing and there are quite a few studies on exactly that. "Dont P1ss your life (life force) away." "Flushing your life down the toilet." Depending on how "talented" one is they may even get a gold medal.

@@vgsschade839 MMM, not even close. The suit is worn so that Tony's auric field (aura) is enhanced to such a degree that each organ is surrounded in its own energetic barrier. An amalgamation of alloyed metals to introduce certain energies and vibrations into the body so that the body may produce its own general and specific auric fields. Superman, Shazam, War Machine, Spiderman, Vision, Wanda and a whole host of others do exactly the same thing. The movie "Chronicle" explains it very well by stating "as long as you see things coming they cannot hurt you, because of the barrier." Explains why Iron Man (for example) on rare occasion has bullet holes in his suit...didnt see them coming. Anti gravity is a weaponized misnomer meant to keep people ignorant, what you mean to say is directional levitation due to controlled vibrations of the body. Some may also call it tactile telekinesis.

[@warrenscipio4168]

Another section that deals with impact is when the flares deployed and the missile goes off right behind Stark and the blast catches and knocks him forward even more, while he wasn't at a stand still being launched by explosions in movies is probably one of the most common underestimations of inertia in movies. We can assume the suit protects against a lot of heat transfer, the quick pressure change and possibly even a little of the impact, but based on how he moved forward most likely he was close enough to the blast to experience the delta between his speed and the explosions speed in acceleration, which is likely enough to smash his brain against the inside of his skull or cause "shell shock" (we'll assume the suit also prevents whiplash since it can support his neck, good luck supporting the neurons in the brain)

Iron Man's armor has Inertial dampeners. This is one more piece of impossible technology that makes the suit work. That's why he can survive a collision with an airplane's wing. It's also why he can jet into the atmosphere w/o visible signs of stress from G forces. Like the arc reactor it's never fully explained.

[@eugene8498]

Tony has to have a suit dimension in there. v^2 - v0^2 = 2 * a * S, simple as that. No damper that could fit into the space in a suit could have damped the g forces from such collision and radical change of speed. So mathematically impossible technology indeed.

The arc reactor, at least at the start, is (I think) a cold fusion reactor. The palladium core is based of a theoretical idea that was tried for a while to use palladium to catalyze room temperature fusion. It didn't work of course, but I think thats what this is based off of.

[@VegasTigger]

One thing not addressed in the physical mechanics of IM is the frailty of the organism in the suit.

How big it looks to a Radar. RADAR RAdio Detection And Ranging. Stealth aircraft: looks very small. Much smaller than it really is. You can do this by making it paper-thin, making it absorb or knock off whatever’s detecting it, not emitting easy to spot exhaust, and more. Lastly, UAV, Unmanned Armed/Ariel Vehicle. Drones, robots, droids, you name it, sci-fi has it. We have lower-end ones as well. 7:15: I forgot Bogey! 7:35 looked like a CIS… 8:17 what I heard was a gold-titanium mix for the suit, but I’m pretty sure he has that as a coating over tungsten carbide.

Thanks for the video, I appreciate your review. After watching it, I do have a couple questions from a layman's point a view. 1. You say the warheads that come out of the missile are not guided. But they come out in all different direction and orient themselves in a fairly uniform pattern. What could cause that if not for onboard guidance? Plus, they have propulsion which would seem to suggest some level of guidance. 2. Tony tests the control surfaces on his suit so we know they are there. But would they be effective considering the shape and position? Lastly, I was also a bit disappointed in how the Iron Man suit came out unscathed after tearing off a wing from a military jet.

[@AviationAustin]

1. Stabilizing isn't necessarily mean guidance. They could have some sort of gyroscope that orients them without specifically guiding them to a target. 2. normally it wouldn't be too effective but because he flies on his belly and very fast any small control surface would/ thrust vectoring would be effective. Even if they're not in an optimal location. Great questions!

[@reaganharder1480]

A close look at the individual "warheads", they really look like just smaller missiles, complete with fins and propulsion and everything. Fins (when properly designed/placed) will stabilize a projectile quite passively, and propulsion in no way means a projectile is guided. And what constitutes "guided" is a bit of a fuzzy term anyway if we're being honest. If I recall correctly, the German V1 in WW2 was "guided" by a gyroscope and possibly a magnetic compass, and were easily knocked off course by carefully tipping the wing with your own aircraft. That said, quite likely this missile system is designed to establish a ballistic trajectory with a guided carrier rocket, and then split into the individual warheads to strike across a wide area for something like lethal area denial.

The handle that the pilot is attempting to pull on the ejection seat is called an emergency manual chute handle. It is a backup in the event that the primary mortar cartridge does not deploy the parachute or if the restraint harnesses re not released from the seat to allow seat-man separation.

[@victorunbea8451]

The repulsors (propulsion) works by taking in air, turning it into a plasma (free nuclei and electrons floating around), then taking the free electrons from the plasma and colliding them to form muons which are about 200 times heavier than electrons but also have a half-life (time to decay to half the number of particles) of a few microseconds, and shooting them out the ends by means of electromagnetic propulsion similar to an ion drive. To make a man fly with a particle drive you would need an insane amount of energy to accelerate the particles to within a fraction of a fraction of a fraction of a fraction of the speed of light. Luckily he has like 3 large scale nuclear reactors' worth of energy strapped to his chest.

I am not sure about the aero dynamics of the Iron Man suit. Assuming you can build thrusters, power source, navigation system, etc. into the suit to make it float in the air and move it around. But how would you be able to fly it the way Tony does? There are MAIN thrusters at the back, under the feet, on the palms; I find it hard to image how he can fly Superman style (without arms extended to the front). How does the placement of the thrusters create enough lift if he were to fly Superman style? I tend to believe a suit like that would allow the person to fly Green Goblin style (in an upright position) instead.

[@hackysackmonster]

I'm no enginerd, but I'd love to hear an explanation on how Tony managed the heat generated from the leading edges of his suite and propulsion.

[@zeroraptor]

I don't think his propulsion creates much heat beyond air friction or I would think his work shop/cars would have caught fire or melted and I think if it would create heat it would be too hot to use in the no suit testing phase. But I could be completely wrong.

[@bert3163]

By panting.

[@PeterDB90]

I never actually thought about the "propulsion" aspect of it. You're right, even if that arc reactor is a mini-nuclear power station that can generate enough energy for Ironman to use however he pleased, you can't propel yourself with energy alone - it's not like he can shoot energy out of his hands and feet and use them to fly. But, since we are talking about a movie where arc reactor is a thing, why not mini jet engines all throughout his body - channels that suck in air and push it out of his feat and hands with such force that propulsion happens? It's not something that would cause light/fire like in the movies but is it really any crazier than the idea of an arc reactor?

[@AviationAustin]

There is a jet suit that does actually exist that uses jet engines. But it has limited range and capabilities. It also requires the user to wear the fuel on a giant pack on his back.

[@TwinShards]

Well tbh technically there is already real way to create propulsion using electricity alone (ion-propulsor). But not at the scale of lifting 300+ pound human flesh+armor. Just push satelite faster and faster in friction-less, empty void space. Maybe in the far future we, as human will have built Ion-Propulsor capable of doing what is happening in the movie with Stark ;) Only time will tell. The only part that it truly doesn't make logical sense is when he build a suit in a cave. I rly doupt he would have the material to do it.

Yeah, that was my biggest complaint too with those seats. The ACES II system is designed without the pilot in mind because they will most likely be unconscious flying at those speeds. If it's a low speed, low opening ejection, it won't be as bad, but still could be G LOC regardless. Having worked directly with Egress for several years on the F-15's at Kadena, I can also say that those helmets and masks are incorrect for the F-22. The mask would be a MBU-20/P and each helmet is actually designed specifically for each pilot using laser measurements. They also have a ton of HUD inside the visor of the helmets to give the pilots way more SA. Granted, they can't show all that since a lot of it is secret, but they could have done a slightly better job with it. Overall though an excellent movie! And a fantastic video!

The most realistic part I've seen in the first Iron Man is Mark 1 or the suit he uses to get out of his imprisoned area. It actually makes perfect sense and is 100% possible to make in real life. There is no real unreal parts in the suit. It has flamethrowers on the ends of where Tony is able to grab onto, it has a jet pack installed in the boots a little around the torso I believe, and it has the most complex design. It's one of those designs that would be a nightmare to draw but when you are just making it out of scratch like Tony did, it makes perfect sense to be a little crazy looking. Either way I do find Mark 1 to be the only plausible suit to make besides the flying prototype that was just silver.

The thing that always lost me from a reality aspect was when he would take a hit from something (direct hit from a tank round for example) and be complete unscathed. Regardless of whether the suit material withstood the blow, the human inside the shell would be completely destroyed. His organs, brain, ect would just be destroyed from the impact alone.

[@austinbambooinc2507]

The arc reactor was originally based on an experiment done with large vacuum tubes, concentrating a huge amount of electrons between parabolic dishes with a resonant alternating current frequency. Apparently it started shaking the whole building before they shut it down. The repulsors that Iron Man uses for flight were based off an effect when like poles of a magnet are fixed at an angle to each other. It was deemed impractical material strengths and the high current needed to get enough force to move something. It may have had better results with pulsed or alternating current at certain frequencies, but it wasn't pursued other than as the background for comics.

The fundamental science of Ironman is that he died as soon as he hard landed one time. At least the suit contained the goo that his body liquified into as soon as all the g forces tore his body to pieces inside of it. The scene where Ironman is flying along at 400 miles per hour ,the tank shell hits his suit and he barrels into the ground at 500 or so miles per hour is hilarious. First off,hell of a shot, tank crew. Secondly,from initial explosion,Ironman is a spam sandwich inside that suit. But it's a comic book story.

From a bio mechanical standpoint, it stands out to me during Tony’s initial flight tests that his legs aren’t straight for extended amounts of time. With thrust from your boot (only 2%, I know) that’s enough to lift you off the ground, I’d think that holding that position would be very difficult. Of course, he corrects it with his straight leg stance for take off and landing later. Tony always learns from his mistakes! I am nitpicking though.

[@Nuetral768]

You left out one my father mentioned (he was a career ECS engineer)... The ice that formed on the suit (major device in the final scenes of this movie BTW) wouldn't actually present at all. Beyond a certain altitude the isn't enough moisture in the atmosphere to contribute to such a problem, and the altitude required to reach said temperatures required to cause such a rapid freezing would prohibit the necessary moisture. Not only that but the speed and design necessary to facilitate the kind of flight responsible for such an occurrence would prohibit dragging moisture on the suit into that level of our atmosphere (in short, this would never happen as depicted). PS: I think he also said something about the quoted altitude being a non-issue altitude as it pertains to facing any combination of these issues. (None of this even comes close to addressing the issue of air friction that would naturally leave the outside of the suit insanely hot even potentially hours after landing.) So in short the whole ice phenomena depicted in the first movie makes no sense, the hit raptor wing actually makes more sense than that even (as vibranium was used in multiple Iron Man suits by Stark, not to mention that an incredible amount of shock absorbers would be required just to change direction or land in such a suit, let alone take a direct shot from a tank them fall out of the sky without dying... that's the sci-fi aspect at work).

My issue with the Iron Man suit is the G force and the effect it would have on Tony's blood. Pilots have to wear a G suit that compresses their legs and abdomen to keep blood in their brain. Otherwise, the G force can push all of their blood toward their feet and they lose consciousness while flying. And that's the case when they're sitting upright in a pilot seat! Iron Man flies head-first -- not in a sitting position. Any high speed flight in that suit (especially going supersonic) would ensure Tony would lose consciousness almost immediately. Tony would suffer severe brain damage from mere minutes of flight.
