The Challis Heli-Plane was developed to expand the flight envelope of present day rotorcraft and challenge the current technology of tilt rotor aircraft, like the Bell/Boeing V-22 "Osprey".
The Challis Heli-Plane concept design offers simplicity, lower production and maintenance cost, while still providing high-speed capabilities. The Challis Heli-Plane can demonstrate smooth easy transition from hover to cruise, excellent control in the hover, capable of autorotation-engine off emergency landing, capable of high rate of descent, can be scaled to meet various civilian or military needs.

The Challis Heliplane is a high-speed, long-range rotorcraft capable of power-off emergency landings, allowing design certification for civilian missions: presidential transport, medi-vac, search & rescue, etc.
Due to safety requirements, like the ability to execute an emergency power-off landing, there are presently no high-speed, long-range heliplanes available for civilian use. |
