OW IT WORKS
Unlike conventional aircrafts and jetpacks, the innovative JETLEV-FLYER concept greatly improves thrust-to-weight ratio by locating the propulsion engine, fuel system and related systems on a separate vessel tethered behind the jetpack, and uses water as the jet propulsion medium because its high density can carry vast amounts of power at much lower velocities, and generate nozzle reaction forces much more effectively than gases.
All metals used in our JETLEV-FLYER models JF-260 and JF-220 are made of either stainless steel or hard-coat-anodized aluminum with Teflon coating to protect them against corrosion and abrasion.
Hard-coat-anodizing has the equivalent hardness of sapphires, the second hardest natural material known to man behind diamonds.
Every part of our JETLEV-FLYER models is painstakingly made with great precision.
All water seals are made with the same high grade O-ring systems that one would find in deep sea systems.
Critical cables are protected by tough braided sleeves, and electronic control modules and cable terminations are encapsulated in tough polyurethane plastics to keep moisture out.
No expense is spared to make the JETLEV-FLYER system as reliable and low maintenance as possible.
The smoothness, stability, control, performance and ease-of-use surpassed even our wildest expectations.
Once you try the JETLEV-FLYER, you will appreciate why we are so excited over the results.
SAFETY
Extensive research and test results helped us to develop many safety features and „best practice“ operating procedures.
Although falling from height or at speed is inherently risky, from our experience falling from the JETLEV-FLYER is rare, and platform diving from 10 meters has been widely practiced for over a century with excellent safety records.
Central to our safety design is using water as a safety net and enforcing low flight ceilings by restricting hose length.
The jetpack’s 5-point quick-release harness, protective backrest and head support, safety saddle and inherent floatation are just some of the many other safety features..
INHERENT STABILITY AND EFFORTLESS CONTROL
Even though the jetpack can generate upwards of 700 lbf (3150 N) of thrust for lift and propulsion, the flight controls are isolated from that thrust and only take a few ounces of effort to adjust.
FLEXIBLE SUPPLY HOSE/TETHER
A flexible water supply hose delivers power to the jetpack with pressurized water.
It also serves as the tether, enforces a flight ceiling, discourages the pilot from flying over land, acts as a stabilizer, dampens vibrations and maintains forward heading stability of the jetpack in flight.
HIGH POWER-TO-WEIGHT RATIO
Traditional designs of airplanes suffer from low thrust-to-weight ratios which limit their performance and agility.
Even F/A-18 E/F fighter jets can barely overcome the force of gravity.
To achieve a dramatic improvement in this ratio, we decided to locate the propulsion source on a separate boat-like unit and transmit low pressure, high flow water to the jetpack through a supply hose and generate thrusts by nozzle reaction force.
SIMPLE, INTUITIVE FLIGHT CONTROLS
Fly-by-wire digital throttle control; nozzles angles determine allocation of thrust between lift and propulsion (forward, neutral or reverse); differential nozzle deflection generates yaw moments; and weight shifting from side-to-side generates roll moments.
Our JETLEV-FLYER models are very simple to learn and operate. Intuitive flight controls, inherent stability and an effective training system mean that most student pilots can learn to fly solo within a few minutes of in-water instructions.
