The turbojet is an airbreathing jet engine which is typically used in aircraft. It consists of a gas turbine with a propelling nozzle . The gas turbine has an air inlet which includes inlet guide vanes, a compressor, a combustion chamber, and a turbine (that drives the compressor).
The prestigious Collier Trophy for 1952 was awarded to Leonard S. Hobbs, chief engineer of United Aircraft Corporation, for "designing and producing the P&W J57 turbojet engine". The engine was produced from 1951 to 1965 with a total of 21,170 built. Many J57 models shipped since 1954 contained 7-15% of titanium, by dry weight.

Diagram of a typical gas turbine jet engine. Air is compressed by the compressor blades as it enters the engine, and it is mixed and burned with fuel in the combustion section. The hot exhaust gases provide forward thrust and turn the turbines which drive the compressor blades. 1. Intake 2. Low pressure compression 3. High pressure compression ...
The XJ37 was being worked on at the same time as competing Westinghouse axial-flow designs undergoing development, the 19A and 19B, were being test-run through the 1943-45 period, resulting in America's first production axial-flow turbojet engine, the Westinghouse J30, of which some 260 examples were made for the earliest American military jets ...
Only about 500 examples of the BMW 003 were built, [13] [verification needed] but the Fedden Mission postwar estimated total German jet engine production by mid-1946 could have reached 100,000 units a year, or more. [8] The 003 was intended for export to Japan, but working examples of the engine were never supplied.
The YJ93 started life as the General Electric J79-X275, an enlarged version of the General Electric J79 turbojet with "275" meaning Mach 2.75, the engine's target operating speed. [2] This design evolved into the X279 when Mach 3 cruise became a requirement, and ultimately became the YJ93. [3] The engine used a special high-temperature JP-6 fuel.
Later sent to the US in October 1941, becoming the first jet engine to run in North America. W.1A Based on W.1, 1,450 lbf (6.45KN) air-cooled turbine disc and incorporating features intended for W.2. Used for second series of test flights of E.29/39 W4041/G beginning on 16 February 1942, and fitted with fuel barostat. Later featured modified ...
