Air-Elf aircraft concept is to solve road congestion. The core of the concept is a new type of wing, “Air Caterpillar”. It can be transformed in order to meet the needs of flexibility and speed of the aircraft. Air-Elf aircraft not only can take off and land vertically, but also is able to perform high-speed cruising. In addition, Air-Elf is equipped with smooth aerodynamic appearance, clean and efficient hydrogen energy power system, solid frame, to facilitate safe and comfortable cockpit and baggage compartment.
Air Caterpillar” wings consist of a main structure and many small wings. These small wings can move horizontally and circularly to provide lifting force constantly. “Air caterpillar” wings are highly transformable to meet the parking, vertical takeoff and landing, high-speed cruising requirements.
The motivation behind the El Tucura (The Grasshopper) trike was to give paraplegic users the opportunity to enjoy the thrill of off-road downhill mountain biking, promoting it as an integrated nationwide sport. A crank handle drive means hands are free for steering while accelerating and three 180mm disc brakes and a 250mm suspension give added control on those extreme downhills.
