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 …

2020年6月1日 · No engine in jet propulsion is quite like GE’s tiny J85 turbojet. Originally designed in 1954, the J85 is expected to power U.S. military aircraft until at least 2040. That’s not a typo: GE had delivered more than 12,000 J85 engines and its commercial engine variants by the end of its production run in 1988.

J85直径约18英寸（46厘米），长45英寸（110厘米），自重396-421磅（180-191千克），推重比达8:1，多年来J85的推重比在航空发动机中都是最高的。 因此，在GE航空内部被称为“小硬汉”。 有多小？ 汽车改装党经常在二手市场淘换J85，把它装在他们的皮卡上。 在军用飞机中，J85装备最多的 诺斯罗普公司 的轻型战斗机 F-5 “虎”和喷气式教练机T-38“禽爪”。 虽然美国空军已选定由波音/萨博合作研发的新一代喷气式教练机 T-7A “红鹰”，但T-38C“禽爪”仍然会服役到2040年， …

The J85 was the first U.S. small turbine engine to go into production with an afterburner. The most important applications were the Northrop T-38 Talon, the first supersonic trainer, and Northrop F-5 Freedom Fighter, a low-cost fighter used by many nations from the 1960s through the 1980s.

The J85-GE engine, known as the “Little Tough Guy,” powers the F-5 fighter jet and T-38 trainer, with StandardAero providing life cycle-optimized maintenance solutions to extend their operational life.

It is powered by two General Electric J85 afterburning turbojet engines located close together in the aft fuselage, each with 3850 lb of thrust. The first T-38 built flew in 1959. More than...
