Hiller XH-44 - 사진 및 비디오

Hiller Aircraft Company was founded in 1942 as Hiller Industries by Stanley Hiller to develop helicopters. Stanley Hiller, then seventeen, established the first helicopter factory on the West Coast of the United States, located in Berkeley, California, in 1942, under the name “Hiller Industries,” to develop his design for the coaxial-rotor XH-44 미군을 위한 "힐러-콥터". XH-44는 1944년에 가동되었다. Henry J. Kaiser와 협력하여 1945 년 United Helicopters가되었습니다. 전후 몇 년 동안 United Helicopter는 동축 로터 및 꼬리가없는 디자인뿐만 아니라보다 전통적인 모델을 포함하여 군사 및 민간 목적을위한 혁신적인 헬리콥터 디자인을 많이 생산했습니다. 1949년 1월, 힐러 360은 미국을 횡단한 최초의 민간 헬리콥터가 되었다.

The Hiller XH-44 was an experimental helicopter developed by Stanley Hiller Jr. in the early 1940s. It was the first successful coaxial helicopter in the United States and the first helicopter to use all-metal rotor blades. The XH-44 was designed as a proof-of-concept for Hiller’s innovative rotor system, which used counter-rotating blades to eliminate the need for a tail rotor. The XH-44 had a two-seat open cockpit, a tubular steel frame, and a 90-horsepower Franklin engine. It made its first flight in July 1944 and demonstrated excellent stability and maneuverability. The XH-44 was later donated to the Smithsonian Institution and is currently on display at the Steven F. Udvar-Hazy Center in Virginia.
