The first derivative of the CFM56 series, the CFM56-3 was designed for Boeing 737 Classic series (737-300/-400/-500), with static thrust ratings from 18,500 to 23,500 lbf (82.3 to 105 kN). A "cropped fan" derivative of the -2, the -3 engine has a smaller fan diameter at 60 in (1.5 m) but retains the original basic engine layout.
The EAD required CFM56-7B engine fleet fan blade inspections for engines with 30,000 or greater cycles within 20 days of issuance, per the instructions provided in the service bulletin and if any crack indications were found, the affected fan blade was required to be removed from service before further flight.
Turkish Engine Center (TEC) is a joint venture between Pratt & Whitney and Turkish Technic for the maintenance, overhaul, and repair of CFM56 and V2500 turbofan aircraft engines. TEC is located at Istanbul’s smaller international airport, Sabiha Gökçen Airport in Anatolia. TEC started operations in January 2010 and has an annual capacity of ...
Thrust reversal, also called reverse thrust, is the temporary diversion of an aircraft engine's thrust for it to act against the forward travel of the aircraft, providing deceleration. Thrust reverser systems are featured on many jet aircraft to help slow down just after touch-down, reducing wear on the brakes and enabling shorter landing ...
Boeing was one of the first aircraft manufacturers to realise the full potential of the CFM56 engine. Boeing president Thornton Wilson contacted Neumann and Ravaud in 1977 with a proposal for an agreement to replace the engines of the 707 using the CFM56. On March 17, 1977, flight testing of the CFM56 began on the Caravelle flying testbench.
The DC-8-71, DC-8-72, and DC-8-73 were straightforward conversions of the -61, -62 and -63 primarily involving the replacement of the JT3D engines with the more fuel-efficient CFM International CFM56-2, a high bypass turbofan, which produced 22,000 lbf (98.5 kN) of thrust.
It is the second-most ordered jet engine behind the 44-year-old CFM56, [29] which achieved 35,500 orders. [3] Also, on the A320neo, where the engine competes head-to-head with the Pratt & Whitney PW1000G, the LEAP had captured a 59% market share in July 2018. By comparison, the CFM56 had a 60% share of the prior-generation A320ceo market. [29] [30]
CFM International CFM56 The PowerJet SaM146 is a turbofan engine produced by the PowerJet joint venture between Snecma ( Safran ) of France and NPO Saturn of Russia. [ 2 ] Developing 68–80 kN (15,000–18,000 lb f ) of thrust, the SaM146 is used on the Sukhoi Superjet 100 .
