Re: How do jet packs fly and what fuels do they use ??

Rocket belts, jet packs, etc.

According to Dicovery Online , the way jet packs or rocket belts work is

"...the rocket belt consisted of fuel tanks, handlebars, a control throttle and a pair of rocket nozzles. Hydrogen peroxide (H2O2) fuel was fed over fine silver mesh, which acted as a catalyst to produce 1,400-degree steam. The steam was then forced through nozzles to unleash 330 pounds of thrust and 135 decibels of brain-rattling sound."

There was also to be a jet engine powered version. However, the engine slated for that design was dedicated to use in the cruise missile.
