The General Electric J85 is a small jet engine produced by GE Aviation. It was designed to power lightweight aircraft and has been widely used as a turbojet engine since its introduction in 1958. In terms of size, the J85 engine weighs around 740 pounds (336 kg) when fully fueled, which makes it one of the smallest production engines available today. Its compact design allows for easy installation on various types of aircraft, making it an ideal choice for military trainers and small commercial planes. Despite its relatively small size, the J85 engine is capable of producing 3,000 pounds (13 kN) of thrust at maximum power settings. This makes it a reliable and efficient option for engines used in general aviation applications. One notable feature of the General Electric J85 engine is its ability to operate effectively in high temperatures. Its robust design allows it to withstand extreme heat without suffering any significant performance losses, making it suitable for use in desert environments or other hot climates. Throughout its production run, the J85 has undergone several upgrades and improvements. The most notable update was the addition of a single-stage turbine engine in 1968, which significantly improved fuel efficiency while maintaining maximum power output. The General Electric J85 engine is still widely used today, with many military trainers and small commercial aircraft relying on its reliability and performance. Its compact size and efficient operation make it an attractive option for pilots looking for a dependable engine to power their aircraft.
