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.
Southwest Airlines Flight 1380 was a Boeing 737-700 that experienced a contained engine failure [a] in the left CFM International CFM56 engine after departing from New York–LaGuardia Airport en route to Dallas Love Field on April 17, 2018.
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).
The CFM56 is one of the most widely used jet engines in the world, and it would be a good turbine representative for aero-engines. Thanks! - SidewinderX ( talk ) 13:14, 16 December 2009 (UTC) [ reply ]
CFM is the world's largest commercial aircraft engine manufacturer, with a 39% market share as of 2020. [1] It has delivered more than 37,500 of its engines to more than 570 operators. The name CFM is derived from the two parent companies' commercial engine designations: GE's CF series and Snecma's M series.
Places with updated sourcing needed include passages such as "The chevrons reduced jet noise by 1.3 perceived loudness decibels during takeoff conditions, and are now offered as an option with the CFM56 for the Airbus A321", which is cited to a source from 2004.
htis (already cited) states it was the CFM 56-3C for the 737-400 that was grounded as does this, while this article from Flight gives some idea why the fault was missed.Nigel Ish 18:24, 20 May 2010 (UTC) I clarified which subvariants were affected, and added a line about having to replace fan blades in 1800+ already-delievered engines.
CFM International CFM56 [ edit ] I've listed this article for peer review because I have mostly completed a massive update the article, including writing the development and design sections from scratch and updating the rest of the article.
