It was built by Barnaby Wainfan, Rick Dean, and Lynne Wainfan to explore the characteristics and potential of this type of airplane. Pumping pressure at the rotor tip is supplied by rotational forces of the rotor. At liftoff, the rocket engines are aligned parallel to the ground, with the rotor providing most of the liftoff thrust, while the rocket engines are operating at only a small fraction of their rated thrust. As the vehicle climbs, the engines are aligned with the flight directional axis of the vehicle, and remain in this position until orbital velocity is achieved. Upon re-entry, the rotor may provide both lifting and drag forces, and also permits low velocity, controllable approaches to the landing field.
Landing is in a vertical orientation, the same as liftoff.
Yet it remains extremely cost effective to own and operate. XFV requires only minimal routine and scheduled maintenance. Mileage is about 20 miles per gallon, with cruise speeds of up to 80 miles per hour. Inspired by an original idea by the 'Hiller' company in the U.S. dating back to the 50's, the design is based on a 'ducted fan' powered by four small internal combustion engines. The vehicle is designed from the outset with safety and reliability in mind.
