The Federal Aviation Administration (FAA) issued a new airworthiness directive (AD) requiring air carriers to perform checks for CFM International Leap-1B engines on the Boeing 737 MAX Family jets in order to CFM also noted that this is already referenced in Chapter 05 of the LEAP-1A Engine Shop Manual LEAP-1A-05-11-03-01A-0B1B-C. The CFM International LEAP (Leading Edge Aviation Propulsion) engines are high-bypass ratio turbofan engines designed to power the Airbus A320neo family (LEAP The LEAP-1C, the first member of the LEAP ® engine family, was selected by Comac (Commercial Aircraft Corporation of China) as the sole Western powerplant for its new C919 single-aisle jetliner. It offers 737 MAX operators exceptional technical, economic and environmental performance, with a 15% reduction in fuel consumption and CO2 emissions versus current engines, a 50% cut in NOx emissions, and compliance with the most stringent noise The models involved are LEAP 1A / 1B / 1C, CFM56-7B / 5B, CF34, PASSPORT20, etc. I. These engines are known to be installed on, but not limited to, certain Airbus A319, A320 and A321 aeroplanes. Federal Aviation Administration certified an improved high-pressure turbine (HPT) hardware durability kit developed by the company for CFM LEAP-1A engines that power the Airbus A320neo family of aircraft.

RATINGS See Note 1. Some engines like early versions of the GE CF-34 used a compressor inlet profile that was "flush" to the airflow downstream of the fan, which tended to encourage particles to pass on by in the fan discharge. , a Engine type is identified by an engine model list including an identification plug reference: LEAP-1B Engine model list LEAP-1B21, LEAP-1B23, LEAP-1B25, LEAP-1B27, LEAP-1B28, LEAP-1B28B1, LEAP-1B28B2, LEAP-1B28B2C, LEAP-1B28B3, LEAP-1B28BBJ1, LEAP-1B28BBJ2 LEAP-1BxxGyy* *xx denotes model rating Compression Molding Construction Consumer Core Curing Custom Content Cutting bird impact is magnified in the LEAP engine because on its smaller 78-inch/2m diameter fan — the first for single-aisle aircraft to use composites — the smaller blades offer less area to absorb the same impact energy. S. Rev Date Rev Cycle September 1, 2020 [77] ENGINE INDICATING 77‐11‐05 CM. This new engine is efficient with its 40:1 overall pressure ratio. Each of the new narrow-body engines – LEAP from CFM International and the PW1000G from Pratt & Whitney, which inward-facing Variable Bleed Valve doors and a buried High-Pressure Compressor inlet that The heart of a LEAP engine lies in its core, which comprises a high-pressure compressor, combustor, high-pressure turbine, and low-pressure turbine. The 737MAX has a new 69. Leveraging the strengths of its parent companies, GE and Safran Aircraft Engines, the After two years of operational service, the A320neos’ PW1100G and the CFM LEAP-1A engine initial in-service performance are examined.

It has a second generation twin-annular, pre-mixing swirler combustor (TAPS II) and a 2-stage In addition to final assembly, the two GE plants produce the “hot section” (compressor, combustor, high pressure turbine) core for every LEAP engine assembled in U. ratios of civil turbofan engines. , aiming to produce 500 “hot sections” for the high-bypass turbofan engines this year. 9, 2025 Engines & Components blisk parts for use in next generation engines. We wrote last week that modern jet engines have compressor pressure ratios at cruise of around 40:1 for single-aisle engines and 50:1 for widebody engines. It offers operators exceptional technical, economic and environmental performance, with a 15% reduction in fuel consumption and CO 2 emissions versus current LEAP’s vaunted 15 percent fuel burn savings emanates from two areas of the engine: Half comes from the high-pressure compressor, the other half from the fan. “With the fleet operating an average of 10 hours per day, every day, with world-class reliability, LEAP engines have quickly become the workhorse for airline fleets around the globe. This AD was prompted by a CFM International’s advanced LEAP product line is the engine of choice to power the Airbus A320neo, the Boeing 737 MAX, and the COMAC C919.
