The tests require engine manufacturers to carry out at least two tests of the engine, to make sure that the engine can survive a compressor or fan blade breaking off within the engine and a turbine blade breaking off within the engine, without fragments being thrown through the outside enclosure of the engine, creating a contained engine failure.
A jet engine is a type of reaction engine, discharging a fast-moving jet of heated gas (usually air) that generates thrust by jet propulsion. While this broad definition may include rocket , water jet , and hybrid propulsion, the term jet engine typically refers to an internal combustion air-breathing jet engine such as a turbojet , turbofan ...
The type of jet engine used to explain the conversion of fuel into thrust is the ramjet.It is simpler than the turbojet which is, in turn, simpler than the turbofan.It is valid to use the ramjet example because the ramjet, turbojet and turbofan core all use the same principle to produce thrust which is to accelerate the air passing through them.
Some facilities are also equipped to test additional capabilities such as weight and balance, night vision and low lighting, water intrusion, heat soaking, and wind evaluation. [1] Jet engines can be run while installed in the aircraft, which must be restrained by holdback devices to resist the engine thrust.
However, the jet engines that would be developed by Junkers and BMW would differ considerably from those engines used by the He 178, instead favouring the axial flow approach in place of the earlier centrifugal design. [1] [19] Nevertheless, the He 178 programme was a valuable source of test data that aided subsequent development efforts ...
The General Electric J85 is a small single-shaft turbojet engine. Military versions produce up to 3,500 lb f (16 kN) of thrust dry; afterburning variants can reach up to 5,000 lb f (22 kN). The engine, depending upon additional equipment and specific model, weighs from 300 to 500 pounds (140 to 230 kg).
It was designed to test the Whittle jet engine in flight, and led to the development of the Gloster Meteor. [10] The first two operational turbojet aircraft, the Messerschmitt Me 262 and then the Gloster Meteor, entered service in 1944, towards the end of World War II, the Me 262 in April and the Gloster Meteor in July. Only about 15 Meteor saw ...
The first chicken gun, built in 1942 by the US Civil Aeronautics Administration and the Westinghouse Electric and Manufacturing Company, being fired at a glass panel.. A chicken gun or flight impact simulator is a large-diameter, compressed-air gun used to fire bird carcasses at aircraft components in order to simulate high-speed bird strikes during the aircraft's flight.
