The PW4000 is a family of high-bypass turbofan engines for wide-body aircraft, developed from the JT9D. It has various thrust levels, from 50,000 to 99,040 lbf, and powers the Airbus A300, A310, A330, Boeing 747-400, 767, 777, and MD-11.
The PW2000 is a series of high-bypass turbofan engines for the Boeing 757, C-17, C-32A and Il-96M aircraft. It was the first civilian engine with full authority digital engine control and has a thrust range from 37,000 to 43,000 lbf.
The PW1000G is a family of geared turbofan engines produced by Pratt & Whitney for various aircraft, such as the Airbus A220 and A320neo. The engine features a gearbox that improves fuel efficiency and reduces noise, but also faced technical challenges and competition from CFM LEAP.
The JT8D is a low-bypass turbofan engine developed by Pratt & Whitney for early narrowbody jetliners. It has eight models with thrust ranging from 12,250 to 21,000 pounds-force and is also used in military and re-engined aircraft.
