AE2100
The Rolls-Royce AE 2100 is a turboprop developed by Allison Engine Company, now part of Rolls-Royce North America. The engine was originally known as the GMA 2100, when Allison was a division of former corporate parent General Motors. Development On July 11, 1989, Saab-Scania A.B. selected the GMA 2100 to power its new Saab 2000, a 50-seat stretch of the Saab 340 turboprop, in a USD$500 million dollar deal. In July 1990, Industrie Pesawat Terbang Nusantara (IPTN) of Indonesia picked the GMA 2100 as the engine for the twin-engine N-250 regional airliner. Flight testing with a Dowty R373 propeller on a Lockheed P-3 Orion testbed aircraft began on August 23, 1990 and finished after over 50 hours of flight and ground testing. The GMA 2100D3 became the powerplant for the Lockheed Martin C-130J Super Hercules. It made its first test flight on March 19, 1994, which was conducted by Marshall Aerospace on a Lockheed C-130K Hercules testbed leased from the Royal Air Force. Testing ende ...

Turboprop
A turboprop is a turbine engine that drives an aircraft propeller. A turboprop consists of an intake, reduction gearbox, compressor, combustor, turbine, and a propelling nozzle. Air enters the intake and is compressed by the compressor. Fuel is then added to the compressed air in the combustor, where the fuel-air mixture then combusts. The hot combustion gases expand through the turbine stages, generating power at the point of exhaust. Some of the power generated by the turbine is used to drive the compressor and electric generator. The gases are then exhausted from the turbine. In contrast to a turbojet or turbofan, the engine's exhaust gases do not provide enough energy to create significant thrust, since almost all of the engine's power is used to drive the propeller. Technological aspects Exhaust thrust in a turboprop is sacrificed in favor of shaft power, which is obtained by extracting additional power (beyond that necessary to drive the compressor) from turbine ex ...

IPTN N-250
The IPTN N-250 was a turboprop regional airliner designed by Indonesian firm IPTN (''Industri Pesawat Terbang Nusantara'') (now Indonesian Aerospace). This aircraft was IPTN's first major effort to win the market share of the regional turboprop class of 64–68 seat airliners. The aircraft's development was eventually terminated after the Asian financial crisis of 1998. As of 21 August 2020, the PA-1 prototype is on displayed at Dirgantara Mandala Museum, Yogyakarta, as its 60th collection. Design and development The N-250 development plan was first revealed by PT IPTN (now PT Dirgantara Indonesia, ''Indonesian Aerospace'') at the Paris Air Show in 1989, but was first introduced in 1986 when the Indonesian Air Show 1986 was held. The N-250 was initially described as a propfan commuter plane, but on 12 July 1990, IPTN selected the Allison GMA 2100 turboprop to power the aircraft. In early 1994, Indonesia announced that Great Britain and four states in the United States were inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Allison Engine Company
The Allison Engine Company was an American aircraft engine manufacturer. Shortly after the death of James A. Allison, James Allison in 1929 the company was purchased by the Fisher Body, Fisher brothers. Fisher sold the company to General Motors, which owned it for most of its history. It was acquired by Rolls-Royce Holdings, Rolls-Royce plc in 1995 to become the US subsidiary, Rolls-Royce North America. History A predecessor of Allison Engine Company, the Concentrated Acetylene Company, was founded in September 1904 by James Allison, Percy C. Avery, Percy C. "Fred" Avery and Carl G. Fisher. Avery was the holder of the patent for the product. This company was the predecessor of the Prest-O-Lite, Prest-O-Lite Company, a manufacturer of acetylene headlights. An explosion at the acetylene gas works in downtown Indianapolis caused the company to relocate out of town, near the race track in Speedway, Indiana. Allison and Fisher raced automobiles at that track, each owning a race car t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lockheed Martin C-130J Super Hercules
The Lockheed Martin C-130J Super Hercules is a four-engine turboprop military transport aircraft. The C-130J is a comprehensive update of the Lockheed C-130 Hercules, with new engines, flight deck, and other systems. The C-130J is the newest version of the C-130 Hercules and the only model in production. , 500 C-130J aircraft were delivered to 26 operators in 22 countries. Development On 16 December 1994, Lockheed received the launch order for the J-model from the United Kingdom's Royal Air Force (RAF). The C-130J launch order occurred after a UK government stalemate of several months that concerned whether to buy new transport aircraft from Europe or the United States. It was paired with a commitment to buy 40 to 50 of the proposed European Future Large Aircraft aircraft (FLA, which was later designated as the A400M). The FLA commitment, which reduced the size of the C-130J launch order, was intended to ensure a 20 percent British workshare in the FLA program, and to prevent ...

Test Flight
Flight testing is a branch of aeronautical engineering that develops specialist equipment required for testing aircraft behaviour and systems. Instrumentation systems are developed using proprietary transducers and data acquisition systems. Data is sampled during the flight of an aircraft, or atmospheric testing of launch vehicles and reusable spacecraft. This data is validated for accuracy and analyzed before being passed to specialist engineering groups for further analysis to validate the design of the vehicle. The flight test phase accomplishes two major tasks: 1) finding and fixing any design problems and then 2) verifying and documenting the vehicle capabilities for government certification or customer acceptance. The flight test phase can range from the test of a single new system for an existing vehicle to the complete development and certification of a new aircraft, launch vehicle, or reusable spacecraft. Therefore, the duration of a particular flight test program c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lockheed C-130K Hercules
The Lockheed C-130 Hercules is an American four-engine turboprop military transport aircraft designed and built by Lockheed (now Lockheed Martin). Capable of using unprepared runways for takeoffs and landings, the C-130 was originally designed as a troop, medevac, and cargo transport aircraft. The versatile airframe has found uses in other roles, including as a gunship (AC-130), for airborne assault, search and rescue, scientific research support, weather reconnaissance, aerial refueling, maritime patrol, and aerial firefighting.

Royal Air Force
The Royal Air Force (RAF) is the United Kingdom's air and space force. It was formed towards the end of the First World War on 1 April 1918, becoming the first independent air force in the world, by regrouping the Royal Flying Corps (RFC) and the Royal Naval Air Service (RNAS). Following the Allied victory over the Central Powers in 1918, the RAF emerged as the largest air force in the world at the time. Since its formation, the RAF has taken a significant role in British military history. In particular, it played a large part in the Second World War where it fought its most famous campaign, the Battle of Britain. The RAF's mission is to support the objectives of the British Ministry of Defence (MOD), which are to "provide the capabilities needed to ensure the security and defence of the United Kingdom and overseas territories, including against terrorism; to support the Government's foreign policy objectives particularly in promoting international peace and security".
