[N 3] Although Bell's limited fighter design work had previously resulted in the unusual Bell YFM-1 Airacuda, the Model 12 [11] proposal adopted an equally original configuration with an Allison V-12 engine mounted in the middle of the fuselage, just behind the cockpit, and a propeller driven by a shaft passing beneath the pilot's feet under ...
The Piasecki X-49 "SpeedHawk" is an American four-bladed, twin-engined experimental high-speed compound helicopter developed by Piasecki Aircraft.The X-49A is based on the airframe of a Sikorsky YSH-60F Seahawk, but utilizes Piasecki's proprietary vectored thrust ducted propeller (VTDP) design and includes the addition of lifting wings.
The AI-25 was designed to power the Yakovlev Yak-40 tri-jet airliner, often called the first regional jet transport aircraft, and is the starting point for the Lotarev DV-2 turbofan engine. [1] The project was launched in 1965, with the AI-25s first test flight in 1966, and finally cleared for production in 1967.
The 2150A design rights were sold in 1967 to used aircraft parts supplier George Varga who formed the Varga Aircraft Corporation. The Varga 2150A Kachina was built at Chandler, Arizona between 1975 and 1982. 121 2150A Kachinas were completed together with 18 examples of the Varga 2180 with a 180 hp Lycoming O-360-A2D engine.
The Pratt & Whitney/Allison 578-DX was an experimental aircraft engine, a hybrid between a turbofan and a turboprop known as a propfan. The engine was designed in the 1980s to power proposed propfan aircraft such as the Boeing 7J7 and the MD-91 and MD-92 derivatives of the McDonnell Douglas MD-80. As of 2019, it is still one of only four ...
A new engine was introduced in 1937: the six-cylinder C6S-4 model, rated at 400 hp at 3300 rpm and 70 in of manifold pressure. It was the first Menasco that really had the power potential to win the Thompson Trophy race. The first prototype went to Rudy Kling for his new Folkerts SK-3 racer in early 1937.
The engine consists of a three-staged fan, seven axial stage compressor arrangement, single stage low and high pressure turbines, an augmentor, and produces maximum thrust of 16,000 lbf (71.2 kN) in the original F404-GE-400 model. The engine was designed with a higher priority on reliability than performance.
