Ironman Suit -- Is it possible?

[ayoimMac13]

TL;DR: Ironman

Can you build an ironman suit?
To what i have come so far no. But i could assemble metall sheets thogeter or so and put a fan at the feet and hands to sostain around 87 kilos
or so.
What do you think?
Wright back if you have ideas

Well, ignoring physics for now, suits powered by external propulsion have been invented. The water jet pack can lift a person, but requires external power and uses water instead of air. The Iron Man suit is basically a jet pack in a suit form factor. Jet packs that use on-board power sources are being developed, but have limited range. And of course, none can go as fast or as high in altitude as Iron Man could do in the movies. I had to answer, cos Iron Man got me into the movie franchise.

Edit: I don't think you can build one yourself, unless you have access to a lab. Even then, you would need formal training in aerospace. But, is it possible for well-funded labs to make a pack to lift a man for a short duration? Yes.

Basic 'flying suit' ?
Well, there's the classic 'jet pack', running on 'HTP' H₂O₂ mono-propellant. Upside, flown on 'James Bond' and, in real-life, lit Olympic Stadium flame.
Down-side(s), 'HTP' is *seriously nasty* and, IIRC, less than a minute flight time...

I've seen a 'jet suit' with four mini jet engines as developed for *serious* R/C models, one per arm & leg. IIRC, flight duration is 'good' but control 'A Tad Fraught'.

Quad/Hex/Octo copter drones now have sufficient lift capacity and useful range, so ducted fans may apply. Uh, aren't Ukraine trialling them for 'Medevac' ??

So, are you going for electric power plus ducted fans ? Jet engines ? 'Combustion' Rocketry with mono or multi propellants ? 'Thermal' Rocketry with electric power plus inert propellant ?

A possible contender is valve-less pulse-jet, those 'flying trombones' with resonant pipe. Upside, the things work and have remarkable power/weight. Down-side, they are really, really loud. Totally anti-stealth. Yes, they also run red-hot, but I suppose you could fit them with a 'muzzle shroud', heating of air within shaped duct providing 'negative drag'...

On the 'gripping hand', pulse-jets exhibit 'bad vibes' without sufficient vehicle 'fly-wheel' mass. IIRC, the scant-few V_1 test pilots had *unkind* things to say about that aspect of their ride...
Taking a leaf from young field of 'Pulse Detonation' jet engines, if several valve-less pulse-jets could be co-ordinated to fire as a three-stage multi-vibrator, a 'flip-flap-flop', ride may improve.
Obvious analogy is the magnetron with its 'linked' resonant cavities...
Perhaps as 'after-burner' for small fan-jet, with compressor-bled 'puffer' air for flight control, while fan blows, cools the 'muzzle shroud' ??
