Boeing Vertol proposed its Model 222 (not to be confused with the later Bell 222 conventional helicopter), in which the engines were in fixed pods at the end of each wing, and a small, rotating pod with the rotor was slightly closer to the fuselage on the wing. This design simplified the engine design by keeping it horizontal at all times ...
Developed in 1984 with stretched fuselage and two Allison 250-C28C turbine engines. Bo 105LS A3 Developed in 1986 with maximum take-off weight increased to 2,600 kg. Bo 105LS A3 "Superlifter" Developed in 1995 with maximum mission weight increased to 2,850 kg. Bo 105M Light transport and surveillance helicopter for West German Army.
During the course of the competition, the Bell submission, the YOH-4, was eliminated as being underpowered (it was powered by the 250 shp (186 kW) T63-A-5). [5] Accordingly, the bidding for the LOH contract came down to Fairchild-Hiller and Hughes. Ultimately, Hughes was selected as the winner of the competition. [6] OH-6 helicopter in flight
The Bell D-292 was developed under the US Army's Advanced Composite Airframe Program (ACAP), which was a project to develop an all-composite helicopter fuselage, considerably lighter and less costly to build than predominantly metal airframes, in support of the LHX program.
A new, full-size replica of the Airwolf helicopter was created by Steven W. Stull for display in the short-lived Helicopter Headquarters museum in Pigeon Forge, Tennessee that opened in August 2006, using a non-flying Bell 222 with molds taken directly from the originals used in the show.
The OH-58 was originally developed during the early 1960s as the D-250 for the Light Observation Helicopter (LOH). While the rival Hughes OH-6 Cayuse was picked over Bell's submission in May 1965, the company refined its design to create the Model 206A, a variant of which it successfully submitted to the reopened LOH competition two years later.
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 Bell 214 is a medium-lift helicopter derived from Bell Helicopter's ubiquitous UH-1 Huey series. The Bell 214ST shares the same model number, but is a larger, much-modified twin-engine derivative.
