Water Jet Flier
Posted by keelynet on February 3, 2009
This is such a neat idea and especially to train since it won’t hurt when you fall into water versus falling on land.
It’s as close you can get to playing James Bond with his personal jetpack!
“We’ve all dreamt, with tears in oureyes, of one day flying with a jet pack. The inherent danger of falling and/or exploding were almost as much as of a deterrent as the price tag.
Now, that dream is closer to our grasp. This system, looks like it is basically just a pump that drags along behind you pushing water through nozzles on your back.
A new design for jet packs uses a system of conduits to push water from an engine below the surface of a lake through thrust nozzles on the pack.
Raymond Li’s terrifying contraption, described as a “personal propulsion device,” just became U.S. Patent 7,258,301. Powered by a clever system of conduits that lead to independently pivoting thrust nozzles, it’s designed to provide inherent stability using “throttle controls and the like.”
Typically, flight packs include propulsion devices such as propellers, rotor blades, or rockets, which often require a highly flammable fuel in order to generate sufficient thrust for flight. In addition to having a reservoir of volatile fluid attached to the body of a pilot, the close proximity of the propeller, rotor blades, or rocket exhaust to the pilot further poses significant safety risks. …
As an alternative to employing the combustion of volatile fluids to directly generate thrust, the high-pressurization of non-flammable fluids, such as water, has been proposed to create sufficient thrust in order to achieve flight.
Any flammable stuff, therefore, only ever sees the dark interior of a combustion engine floating on the water, powering the pump. No rotor blades, no hot gases (except the motor’s exhaust), just plumes of pressurized water.” – Patent and this excellent Video.
