Research into the next generation of commercial jet engines, high-bypass ratio turbofans in the "10-ton" (20,000 lbf; 89 kN) thrust class, began in the late 1960s. Snecma (now Safran), who had mostly built military engines previously, was the first company to seek entrance into the market by searching for a partner with commercial experience to design and build an engine in this class.
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.
In terms of volume, the most impactful commercial aero engine produced by Safran Aircraft Engines is the CFM International CFM56 turbofan powerplant. This engine is both developed and manufactured via a 50-50 joint venture company, CFM International, which Safran jointly owns with the American industrial conglomerate General Electric (GE).
Over the first half of 2019, CFM revenues were up by 23% to €5.9 billion with 1,119 engine deliveries; declining sales of CFM56 (258 sold), more than offset by LEAP (861 sold). [5] Recurring operating income rose by 34% to €1.2 billion , but was reduced by €107 million ( US$118 million ) due to the negative margins and initial costs of ...
For a new CFM International CFM56-3 the margin is 53 °C. [ 148 ] [ 43 ] Kraus [ 149 ] gives the effect on increased fuel consumption of typical component degradation during service. The Pratt & Whitney JT8D has a full length fan duct which is a rigid case construction which resists inlet air loads during aircraft rotation.
ADC (from "Aircraft Disposal Company") [3] bought 35,000 war-surplus engines in 1920. Initially produced engines from Renault 70 hp spares.. ADC Cirrus. ADC Airdisco; ADC Cirrus; ADC Nimbus, development of Siddeley Puma
CFM International CFM56: The General Electric F101 is an afterburning turbofan jet engine. ... In full afterburner it produces a thrust of more than 30,000 pounds ...
Thrust reversers deployed on the CFM56 engine of an Airbus A321. 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.
