The Republic XF-84H "Thunderscreech" is an American experimental turboprop aircraft derived from the F-84F Thunderstreak.Powered by a turbine engine that was mated to a supersonic propeller, the XF-84H had the potential of setting the unofficial air speed record for propeller-driven aircraft, but was unable to overcome aerodynamic deficiencies and engine reliability problems, resulting in the ...
Following an engine shutdown, a precautionary landing is usually performed with airport fire and rescue equipment positioned near the runway. The prompt landing is a precaution against the risk that another engine will fail later in the flight or that the engine failure that has already occurred may have caused or been caused by other as-yet unknown damage or malfunction of aircraft systems ...
(Model 500) The 4,100 shp (3,057.37 kW) turboprop origin of the T38, [5] composed of two power sections driving a common gearbox. [2] [8] T44 (Model 503) large turboprop with three T38 engine sections. T56 (Model 502) enlarged and improved version of the T38, destined to enter service by the tens of thousands.
The T40 concept originated at Allison in 1944, where design studies were carried out on a 4,000 shp (2,983 kW) turboprop engine. Taking advantage of this effort, the US Navy awarded Allison a contract for the design and development of a 4,100 shp (3,057 kW) turboprop engine.
Qantas Flight 32 was a regularly scheduled passenger flight from London to Sydney via Singapore.On 4 November 2010, the aircraft operating the route, an Airbus A380, suffered an uncontained failure in one of its four Rolls-Royce Trent 900 engines.
Contra-rotating propellers Contra-rotating propellers on the Rolls-Royce Griffon-powered P-51XR Mustang Precious Metal at the 2014 Reno Air Races. Aircraft equipped with contra-rotating propellers (CRP) [1] coaxial contra-rotating propellers, or high-speed propellers, apply the maximum power of usually a single piston engine or turboprop engine to drive a pair of coaxial propellers in contra ...
After service trials the aircraft were delivered to a U.S. Navy air transport squadron, VR-2, on 31 March 1956. Problems with the engine/propeller combination led to the ending of Tradewind operations and the unit was disbanded on 16 April 1958. The six R3Y-2s were converted into four-point in-flight tankers using the probe-and-drogue method.
Military turboprop variant. 545-B2 Internal designation for the baseline T78 turboprop. [10] The engine targeted a BSFC of 0.3 lb/(hp⋅h) (180 g/kWh) to match reciprocating engine rates of BSFC. Chosen by the U.S. Navy in July 1963 to install on anti-submarine aircraft. Also drew U.S. Air Force interest as a high-endurance missile-launching ...
