It was later adapted with an afterburner for supersonic designs, and in this form it was the world's first production afterburning turbofan, going on to power the F-111 and the F-14A Tomcat, as well as being used in early versions of the A-7 Corsair II without an afterburner. First flight of the TF30 was in 1964 and production continued until 1986.
An afterburner (or reheat in British English) is an additional combustion component used on some jet engines, mostly those on military supersonic aircraft. Its purpose is to increase thrust , usually for supersonic flight , takeoff, and combat .
It had replaced the afterburner-equipped Pratt & Whitney J57-P-20A turbojet engine of the F-8. [6] The same engine had also powered several other combat aircraft of the era, including the General Dynamics F-111 Aardvark and early Grumman F-14 Tomcats. The TF30-P-6 did not require an afterburner for its subsonic role. [2]
Despite having large differences in static thrust, the TF30-equipped F-14A and the F110-equipped F-14B and F-14D were rated at the same top speed. [N 2] [59] [60] In 1996, two F110-equipped Tomcat crashed after an afterburner failure. In the second crash, lighting the afterburner damaged the afterburner can's lining and led to an explosion.
The Pratt & Whitney J58 (company designation JT11D-20) is an American jet engine that powered the Lockheed A-12, and subsequently the YF-12 and the SR-71 aircraft. It was an afterburning turbojet engine with a unique compressor bleed to the afterburner that gave increased thrust at high speeds.
The Pratt & Whitney F100 (company designation JTF22 [1]) is a low bypass afterburning turbofan engine. It was designed and manufactured by Pratt & Whitney to power the U.S. Air Force's "FX" initiative in 1965, which became the F-15 Eagle.
The General Electric F110 is an afterburning turbofan jet engine produced by GE Aerospace (formerly GE Aviation). It was derived from the General Electric F101 as an alternative engine to the Pratt & Whitney F100 for powering tactical fighter aircraft, with the F-16C Fighting Falcon and F-14A+/B Tomcat being the initial platforms; the F110 would eventually power new F-15 Eagle variants as well.
The F401 produced 14,871 lbf (66.15 kN) in max continuous power, 16,489 lbf (73.35 kN) in military power, and 28,096 lbf (124.98 kN) augmented (in afterburner). This engine was intended to replace the TF30 in the originally planned F-14B and a prototype was first flown in 1973. [6]
