The American Helicopter Society (AHS) International's Igor I. Sikorsky Human Powered Helicopter Competition was a competition to achieve the first human-powered helicopter flight to reach an altitude of 3 m (10 ft) during a flight lasting at least 60 seconds, while remaining within a 10 m (32.8 ft) x 10 m (32.8 ft) square, and complying with other competition requirements.

The Boeing-Sikorsky design carried ordnance within upward swinging gull-wing doors in the sides of the fuselage and featured a fenestron tail rotor. The program's name was changed to Light Helicopter (LH) in 1990. [6] In April 1991, the Boeing-Sikorsky team was selected as the contest winner and received a contract to build four prototypes. [7]

Sikorsky has said that the X2 design is not suitable for heavy-lift size, and instead suggests the CH-53K for heavy-lift and tiltrotor for the ultra-class. [28] However, Sikorsky plans to build the 30,000-pound-class (14,000 kg) JMR-TD (with a cabin 50% larger than the Black Hawk ) at full scale to remove doubts about the scalability of the X-2 ...
The Sikorsky HH-52 Seaguard (company designation S-62) is an early amphibious helicopter designed and produced by American helicopter manufacturer Sikorsky Aircraft. It was the first of the company's amphibious rotorcraft to fly and the United States Coast Guard's first turbine-powered helicopter and first amphibious helicopter.
The design usually had 4 wheels to land on, some had combined wheel and ski, and there was a version with twin floats. Flight control on the HH-43 was primarily effected by a series of servo-flaps, or large tabs, that was located on the trailing edge of each rotor blade; the actuation of these flaps [ how? ] would cause the rotors to warp and ...
