Object Details

Physical Description: Type: Turbojet; Thrust: 75,600 N (17,000 lb); Compressor: 16-stage, 2 spool axial; Combustor: Cannular; Turbine: Single-stage high pressure, 2-stage low pressure axial; Weight: 2,703 kg (5,960 lb)
Summary: First announced in 1954, Pratt & Whitney's J75 engine was developed from its J57 with a similar component arrangement, but with design features emphasizing weight control. Production began in the spring of 1957, and both afterburning and non-afterburning versions were manufactured. J75 engines were rated at 109 to 118 KN (24,500 to 26,500 lb) thrust with afterburner, depending on the model.; The J75 powered the Convair F-106 Delta Dart - the first U.S. operational Mach 2 fighter-, the Republic F-105 Thunderchief fighter-bomber, and North American F-107A. The commercial version, known as the JT4, was certificated in March 1957, and was used on the Boeing 707-220/-320 and the McDonnell Douglas DC-8-20/-30 airliners.; The Lockheed U-2 reconnaissance aircraft was originally powered by the Pratt & Whitney J57 and later by the J75. This J75-P-13B, an experimental Pratt & Whitney engine, was installed in NASM's Lockheed U-2C aircraft to represent the later type of engines used in it.
