T406
The Rolls-Royce T406 (company designation AE 1107) is a turboshaft engine that powers the Bell Boeing V-22 Osprey tiltrotor. The engine delivers 6,000 shp (4,470 kW). Development In 1982, Detroit Diesel Allison (DDA) prepared a new engine design to enter the United States Army's Modern Technology Demonstrator Engine (MTDE) competition, which was expected to be developed into the powerplant for the United States Navy's JVX experimental tiltrotor aircraft program (which would eventually become the Bell Boeing V-22 Osprey). After this engine, which DDA called the Model 580, lost the competition to Pratt & Whitney and General Electric in 1983, Allison was separated from Detroit Diesel as a separate division within General Motors, and Allison's new management decided to pursue the V-22 engine contract anyway. On 24 December 1985, the U.S. Navy selected Allison's engine for full-scale engine development and production on the U.S. Marine Corps's V-22 Osprey. Before the engine ...

Rolls-Royce AE 3007
The Rolls-Royce AE 3007 (US military: F137) is a turbofan engine produced by Rolls-Royce North America, sharing a common core with the Rolls-Royce T406 (AE 1107) and AE 2100. The engine was originally developed by the Allison Engine Company, hence the "AE" in the model number. Development In 1988, Allison Engine Company (then owned by General Motors) and Rolls-Royce plc began joint studies of a RB580 to power the proposed Short Brothers FJX regional jet, combining the T406 core with a Rolls-Royce low-pressure spool. By late 1989, amid growing importance of the Rolls-Royce Trent engine and uncertainty over the Short Brothers project, Rolls-Royce quit. Allison Engine Company pursued the engine alone, revising the design as a new wide-chord snubberless (or clapperless) titanium fan and low-pressure turbine. On March 23, 1990, Allison's GMA 3007 was selected to power the Embraer EMB-145 regional jet. In September 1990, it was selected for the Cessna Citation X. The engine was fi ...

MPC 75
MPC 75 was an aircraft project of the company "MPC Aircraft GmbH" a subsidiary of "Deutsche Airbus". Work on the project was done mainly between 1988 and 1992 in Hamburg, Germany. Predevelopment work was finished, however the project never got the "go ahead" and never made it into full development. Development On 3 October 1985, Messerschmitt-Bölkow-Blohm (MBB) of West Germany signed a memorandum of understanding (MoU) with China National Aero-Technology Import & Export Corporation (CATIC) to jointly study the feasibility of an aircraft designated the MPC 75, a propfan-powered regional aircraft that would seat 60 to 80 passengers. On 6 June 1986, the companies agreed to another MoU during the 1986 Hanover ILA air show to start the second phase of feasibility studies. MBB also signed an MoU at that event with General Electric to determine whether its unducted fan (UDF) propulsion technology could be scaled down to power the MPC 75. The results of the feasibility study were r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allison T56
The Allison T56 is an American single-shaft, modular design military turboprop with a 14-stage axial flow compressor driven by a four-stage turbine. It was originally developed by the Allison Engine Company for the Lockheed C-130 Hercules transport entering production in 1954. It has been a Rolls-Royce product since 1995 when Allison was acquired by Rolls-Royce. The commercial version is designated 501-D. Over 18,000 engines have been produced since 1954, logging over 200 million flying hours. Design and development The T56 turboprop, evolved from Allison's previous T38 series, was first flown in the nose of a B-17 test-bed aircraft in 1954. One of the first flight-cleared YT-56 engines was installed in a C-130 nacelle on Lockheed's Super Constellation test aircraft in early 1954. Originally fitted to the Lockheed C-130 Hercules military transport aircraft, the T56 was also installed on the Lockheed P-3 Orion maritime patrol aircraft (MPA), Grumman E-2 Hawkeye airborne earl ...

Bell Boeing V-22 Osprey
The Bell Boeing V-22 Osprey is an American multi-mission, tiltrotor military aircraft with both vertical takeoff and landing (VTOL) and short takeoff and landing (STOL) capabilities. It is designed to combine the functionality of a conventional helicopter with the long-range, high-speed cruise performance of a turboprop aircraft. In 1980, the failure of Operation Eagle Claw (during the Iran hostage crisis) underscored that there were military roles for which neither conventional helicopters nor fixed-wing transport aircraft were well-suited. The United States Department of Defense (DoD) initiated a program to develop an innovative transport aircraft with long-range, high-speed, and vertical-takeoff capabilities, and the Joint-service Vertical take-off/landing Experimental (JVX) program officially commenced in 1981. A partnership between Bell Helicopter and Boeing Helicopters was awarded a development contract in 1983 for the V-22 tiltrotor aircraft. The Bell Boeing team joint ...

General Electric GE27
The General Electric GE38 is a gas turbine developed by GE Aviation for turboprop and turboshaft applications. It powers the Sikorsky CH-53K King Stallion as the T408. Design and development The GE27 was developed in the early 1980s under the "Modern Technology Demonstrator Engines" (MTDE) program sponsored by the United States Army Aviation Applied Technology Directorate. Sporting a 22:1 pressure ratio, which was a record for single-spool compressors at the time, the GE27 was GE's unsuccessful submission to power the Bell Boeing V-22 Osprey tiltrotor aircraft. The GE27 also had a compressor air flow of and a turbine temperature of . The GE27 first ran in late 1984, but it unexpectedly lost the V-22 engine competition to the Allison 501-M80C, which was not a participant in the MTDE program. In the late 1980s, GE used the GE27 as the basis for the commercial development of turboshafts, turboprops, turbofans, and propfans under the GE38 name. GE formed a 50/50 venture with Gar ...

Free-turbine Engine
A free-turbine turboshaft is a form of turboshaft or turboprop gas turbine engine where the power is extracted from the exhaust stream of a gas turbine by an independent turbine, downstream of the gas turbine. The power turbine is not mechanically connected to the turbines that drive the compressors, hence the term "free", referring to the independence of the power output shaft (or spool). This is opposed to the power being extracted from the turbine/compressor shaft via a gearbox. The advantage of the free turbine is that the two turbines can operate at different speeds and that these speeds can vary relative to each other. This is particularly advantageous for varying loads, such as turboprop engines. Design A free-turbine turboshaft ingests air through an intake. The air passes through a compressor and into a combustor where fuel is mixed with the compressed air and ignited. The combustion gases are expanded through a compressor-driving turbine, and then through a "free" pow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
