How GE Aerospace Engineers Used Science to Solve an Engine Durability Problem with CFM LEAP Engines

Anyone who visited the GE Aerospace chalet at the Paris Air Show, on the grounds of Le Bourget Airport, came away with three distinct impressions: The market for engines is growing, lean is working, and new technologies are on the rise. The GE Aerospace team also inked a number of contracts, announcing growth in its order book across jet engines, services, avionics, and digital offerings. The deals include more than 100 GEnx-1B engines, as well as 70 CFM LEAP-1A engines, 80 CFM LEAP-1B engines, and 37 CF34-8E engines, along with multiple service contracts.

Air India announced on February 14 that it is buying 400 single-aisle and 70 twin-aisle commercial aircraft. To power the larger airliners — Boeing 787 and 777X twin-engine jets — the carrier signed an agreement with GE Aerospace for 40 GEnx-1B and 20 GE9X engines, plus engine services. Air India will also buy more than 800 LEAP engines from CFM International, a 50-50 joint company between GE and Safran Aircraft Engines, to outfit the smaller planes in the order, 210 Airbus A320/A321neo aircraft and 190 Boeing 737 MAX-family aircraft.

LEAP Year may come around every four years, but advanced technology like the LEAP engine only comes around once in a generation!

CFM International’s advanced LEAP-1A engine was today simultaneously awarded Type Certificates by both the European Aviation Safety Agency (EASA) and the U.S. Federal Aviation Administration (FAA).
