In December 1980, Pratt & Whitney changed to a new naming system for its engines and the JT10D became the PW2037. The PW2000 is a dual-spool, axial air flow, annular combustion, high bypass turbofan with a dual-channel full authority digital engine control system. It was certified in 1984 as the first civilian FADEC-controlled aviation engine.
PW205B First run 1987. Flown in twin-engine MBB BO105 for demonstration only. [2]PW206A Maximum continuous power 550 shp (410 kW) [3] for use on the MD Explorer PW206B Maximum continuous power 431 shp (321 kW), [3] for use on the Eurocopter EC135
In 1979 Pratt & Whitney launched its PW2000 engine, claiming 8% better fuel efficiency than the -535C for the PW2037 version. Boeing put Rolls-Royce under pressure to supply a more competitive engine for the 757, and using the more advanced -524 core as a basis, the company produced the 40,100 lbf (178,000 N) thrust RB211-535E4 which entered ...
It was a modification of the Pratt & Whitney J52 turbojet engine which powered the US Navy A-6 Intruder and A-4 Skyhawk attack aircraft. Eight models comprise the JT8D standard engine family, covering the thrust range from 12,250 to 17,400 pounds-force (54 to 77 kN), and power the 727, 737-100/200, and DC-9.
The engines, designated PW535E1, are rated at 3,478 lbf (15.47 kN)/ [4] Unveiled at the May 2023 EBACE show, the FADEC-controlled PW545D is developed for the Cessna 560XL Ascend variant, to be rated at 4,200 lbf (19 kN) and optimized for improved fuel burn and longer time between overhauls (TBO) up to 6,000 hours.

A PW4074 engine had a fan blade failure and associated engine cowl damage as the Boeing 777-200 was climbing out of Okinawa. [18] As of March 2021 the investigation is ongoing. 20 February 2021, United Airlines Flight 328 Boeing 777-200's right hand PW4077-112 had a blade failure shortly after taking off from Denver, causing significant engine ...
[133] [134] The first engine to power the 757-200, the Rolls-Royce RB211-535C, was succeeded by the upgraded RB211-535E4 in October 1984. [135] Other engines used include the Rolls-Royce RB211-535E4B, along with the Pratt & Whitney PW2037 and Pratt & Whitney PW2000-37/40/43. [28] Its range with full payload is 3,850 nautical miles (7,130 km ...
The PW 300 series has been developed in partnership with MTU who are responsible for the low pressure turbine. The first variant, the PW305A, has the following configuration and was designed with a core flexible enough for engines with take-off thrusts from 20 kN to 31 kN (4,500 to 7,000 lb): a single-stage fan driven by a three-stage low pressure turbine, supercharging a four-stage axial ...
