Jetlev flyer
The Jetlev-Flyer is a motor-driven means of transportation similar to a rocket backpack , with which a person can move on and above the water surface by means of a recoil drive with water jets.
functionality
The device developed by the Canadian Raymond Li works as follows: In a boat with a closed body, a four-stroke engine with 120–260 hp drives a flange-mounted high-performance pump . This sucks in water and presses it out through two manually controllable nozzles through an approximately 10 m long, pressure-resistant hose into the drive and propulsion unit attached to the operator's back. By means of the recoil principle , the person rises vertically up to a height of approx. 8.5 meters with steeply positioned nozzles and can then move freely over the surface of the water at a speed of up to approx. 50 km / h with flat nozzles. The propulsion and propulsion unit pulls the boat behind it by means of the hose. The name Jetlev was formed from the words "Jet" for nozzle and "lev" for "levitation" (= floating). The construction principle of the device, which was approved by Germanischer Lloyd as a pleasure craft in winter 2010, is based on US patent no. 7,258,301 protected.
