The future is anti-grav tech. brainlet

>>1703666
fuck you, Satan. You're not fooling me.

>>1703656
if you can figure out how to get usable power other than thrust i guess anythings possible. maybe look up turbo shaft generators, then realize you have no clue what you are at.

>>1703817
An APU is a turboshaft

>>1703656
R/C jet turbines are getting bigger and more powerful every day. An APU has a lot of ancillary gear to haul around. I'm presuming you're just after thrust. If you're looking to use a turbine as a turbine-generator, you could, again, start with a miniature. I'm not sure why you'd want to do that, though. You'd still have batteries, plus you'd have to haul fuel.

>>1703968

This. OP is a moron. May as well harness the power of crystals for thrust.

>if one was to build an exo suit,
build the suit
come back and post pics
then we'll discuss power source

ITT: just another bullshit pipedream that will come to nothing more than waste /diy/s time and a thread.

>>1703656
just use an external power source like in evangelion

You can build a turbojet out of an old diesel truck turbocharger

>>1705113
Wouldn't it be better to design the suit around the power source?

How about you come back when you have a clue what you are talking about?

>>1703656
Did you know that a jet liner is a type of exosuit? So are cars and cranes.

>>1703656
>>exosuit
if you mean exoskeleton, even when the damn thing's plugged into the wall it's still pretty hard to get any augmentation.
>>1706457
No, figuring out the biomechanics, how to actuate it, and control it are going to be difficult problems. Again it's still pretty hard to show that exoskeletons offer any benefits. I think you're gonna have a hell of a time making actuators.

>>1703656
Jets burn a fuckton of fuel, your still going to be limited by the weight of it

>>1703656
The ones behind semi cams. I got one. 13.7hp 2 cylinder perkins diesle.

Makes about as much sense to make a diesle jetpack as a steam powered rocket I guess. Nobody here is ever going to leave the pc or phone to try it though so whatever

>>1703666
>>1703968
>>1705165
>>1706784
Fairly certain OP is looking at an APU as an onboard power source, not a jet pack.

>>1703656
Look up turboshaft engines for RC models. Some can generate 14HP(10kw) like at the bottom of this page: http://www.starwoodmodels.com/

Take output, hook up to appropriate generator and away you go. 10kw is probably enough for nine microwaves

If you want to fuck around with turbine power for any DIY project RC engines are really your only option. gas turbine engines have really good power to weight ratios for the engines themselves when compared to reciprocating engines, BUT as other anons have mentioned they're fuel hogs, and RC turbines are the least gas efficient of any gas turbine. A major factor in GT efficiency is the compression ratio, which is a function of the compressor diameter and RPM. As you shrink the engine, the compressor has to rotate at higher and higher RPM to reach the same compression ratio, making it harder and harder to manufacture materials that can withstand those conditions, or run them at sub-optimal compression which is what RC turbines do

Basically you have to figure in how much power you need and how long you want to run it for and see if it's worth hauling around the power plant + fuel weight when picking an engine type

What about using MagIC? The magnesium injection cycle engine has an insane power density if you can find a way to recharge the magnesium oxide and keep from burning the shit out of yourself.

>>1706457
How are you going to choose a power source if you don't know the suit's weight limit or power consumption?

>>1703656

As someone who is on a team ( begrudgingly) to accomplice building a suit some where between marvels iron man or 40k's power armor, i can tell you that the power source is the biggest puzzle piece that has yet to be solved.
everything else is possible albeit insanely expensive to manufacture as it all custom to a person body structure.

max time with "battery pack is about 10-15mins other wise it is an umbilical power feed which is pointless.

also if you were stupid enough to use an APU if would look like that crappy American and Jap robot fight that was on tv the other day. think they were both diesel powered though.

>>1703656
boston dynamics prototypes frequently use 2 stroke engines

is this why the methheads keep fucking each other in the dumpster next to the run down stores?
