Koun Aircraft Dirigible Helicopter : ウィキペディア英語版 | Koun Aircraft Dirigible Helicopter
The Kouns-Craft, described and registered as a Koun Aircraft Dirigible Helicopter was a patented experimental vehicle designed by Young Ho Koun. Koun was the first Chinese American to develop an aircraft in America. ==Design and development== Koun, a cook by profession, developed the Aircraft Dirigible Helicopter to demonstrate an aircraft with vertical takeoff and landing capability. The vehicle was constructed over the course of five years. The vehicle resembled a conventional light aircraft with the exception of two large airfoil-shaped cuffs over the wings intended to hold compressed Helium. The designer felt that using compressed helium would provide additional buoyancy, requiring less volume than an unpressurized dirigible. The exposed forward mounted engine was designed to tilt for forward or vertical thrust. A set of outrigger wheels on the wingtips were set for stability on the ground.
