500 Lb Thrust small jet engine?

So the fun and crazy side of me has come out again and I have thought up some crazy plans for a jet powered wing suit.  I'm sure many of you have seen the swedish rocket man, he jumps out of planes with a small wing and 4 miniature jets strapped to his back.  That is cool and all, but I would like to look at building something a little more useful than fun, although I could imagine it would be a blast.  The idea is to design a large wing 8-12 feet.  It will be made extremely light, however extremely strong because the wing should be able to handle strong g-forces, tight turns along with possible above mach speeds (probably pushing the boundaries of sanity.  This will probably require a carbon fiber and aluminum structure while requiring a rigid wing surface as apposed to the lighter plasticy flexible covering used by smaller aircraft.  This wing will be able to take off and land, eliminating the requirement of a plane to haul it up and then also not necessarily requiring a parachute (one will be worn at all times)  The wing I imagine will not be any lower that hip height and will also have a v-tail for more control.  Now my question is if anyone knows of a small jet engine that exists and would fit this project,  It would also be possible to fit two, one on the underside of each side.  I am looking for 500 to 1000 lbs of thrust and they need to be very small, and lightweight.  Do any engines of this type exist.  I also may be out of my mind expecting to take off with that amount of thrust,  I just don't imagine the whole thing to weigh more than 200 lbs plus me weighing just under 200 lbs.  So 500 would ideally allow for vertical take off, however it would probably not be practical.  Would an engine with this amount of thrust be suitable for my needs or would I need 1000 to 1500 lbs of thrust.  One big goal is for the wing to be very efficient so I don't want to be wasting fuel, however it would be nice to be able to fly quickly for some local entertainment.  Maybe I would throw on some solar panels for the electronics as well.

I found this
This engine seems pretty substantial, would one or two of these be capable of doing what is needed here?

I doubt "500lbs thrust" and "wearably small" go together easily. Worse, you are going to need to look at 1000-1500lbs thrust for VTOL.

If you want the jets to be wearable, you are going to need to launch from an aircraft, or have some sort of trolley as take-off gear.

Having said that, have you seen this guy's wearable pulse-jets?

Thanks, I have realized as much seeing as each engine would weigh approximately 50 lbs on its own. I do plan on making the wing runway capable of takeoff and landing, so it will have gear of course. Those pulse jets are really awesome! I have always admired them, however I'm not too fond of the noise or heat.

I'm looking at something similar 500 lb of thrust should be plenty, tho if you are trying to take off vertically your eingens. At suck in their own exsaust and stall, that is the same problem that the harrier and Boeing's f35 (not In use, the government used Lockheed Martin ' s design instead) had. Good luck and keep on working

You could Try AMT Jets they have engines that produce 77kgs worth of thrust and one on test producing 150kgs of thrust. you may also want.check out the site jetpackaviation.

they cost like 20 thousand $

secondly you travelling at the speed of sound might have some seriously kinetic heating may be the jet pack wing might survive but I don't know about you.

I had the same thought, found this and thought if you added a set of wings you could use it for stable flight. Vertical take off and landing.

The BD5 Jet flew with several jet engines from 107 LBT to 325 LBT.
Williams make the FJ33, which can deliver up to 1000 lbs of thrust, and there's the classic F107

I shudder to think what the list prices are, and I doubt you'll find one in a surplus shop.
