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 ...
The Douglas A2D Skyshark was an American turboprop-powered attack aircraft built by the Douglas Aircraft Company for the United States Navy.The program was substantially delayed by engine reliability problems, and was canceled because more promising jet attack aircraft had entered development and the smaller escort carriers the A2D was intended to utilize were being phased out.
The T406/AE 1107C Liberty shares a common core with the AE 3007 turbofan and AE 2100 turboprop series of engines, both of which have sold in the thousands of copies. [10] [11] 44-46 percent of parts are common between the T406 and the AE 3007, while about 76 percent of parts are common between the T406 and the AE 2100. [12]
On September 11, 1991, the Embraer EMB 120 Brasilia turboprop, registered N33701, [3] crashed while initiating its landing sequence, killing all 14 people on board. The aircraft wreckage hit an area near Eagle Lake, Texas , approximately 65 miles (105 km) west-southwest of the airport.
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.
Wright R-3350 Duplex-Cyclone Turbo-Compound radial engine.. The first aircraft engine to be tested with a power-recovery turbine was the Rolls-Royce Crecy.This was used primarily to drive a geared centrifugal supercharger, although it was also coupled to the crankshaft and gave an extra 15 to 35 percent fuel economy.
The flight crew was found to be unable to perceive any problem with the airplane until the propeller blade angle was between 24 and 26°. They stated that the airplane would have "become very difficult to control after the propeller reached the 22° stop, so the pilots of flight 2311 most likely did not notice a problem with the airplane until ...
