  • LEAP-1A durability updates extend time on wing for the A320neo family
  • Design validated through proprietary dust testing
  • LEAP-1A耐久性更新延长了A320neo系列飞机的使用时间
  • 通过专有的灰尘测试验证设计

CINCINNATI, Dec. 6, 2024 /PRNewswire/ -- Today, the U.S. Federal Aviation Administration and the European Union Aviation Safety Agency certified the updated high-pressure turbine (HPT) hardware durability kit for the CFM LEAP-1A engines that power Airbus A320neo family aircraft. The durability kit was designed to increase time on wing, especially in hot and harsh environments, and includes the HPT stage 1 blade, HPT stage 1 nozzle, and forward inner nozzle support.

辛辛那提,2024年12月6日 /PRNewswire/ -- 今天,美国联邦航空局和欧盟航空安全局认证了为CFM LEAP-1A发动机设计的更新高压涡轮(HPT)硬件耐久性套件,该发动机为空中客车A320neo系列飞机提供动力。此耐久性套件旨在增加使用时间,特别是在炎热和恶劣的环境中,包括HPT第1阶段叶片、HPT第1阶段喷嘴和前内喷嘴支撑。

CFM LEAP-1A engine undergoing dust testing – a key milestone in the validation of the more durable high-pressure turbine (HPT) hardware that was certified in December 2024.
CFm LEAP-1A发动机正在进行灰尘测试 – 这是验证更耐用的高压涡轮(HPT)硬件的关键里程碑,该硬件在2024年12月获得认证。

"This new hardware is fulfilling our promise to ensure that LEAP-1A engines achieve the same level of maturity, durability, and time on wing that our customers have enjoyed with the CFM56 product line," said Gaël Méheust, president and chief executive officer at CFM International.

“这款新硬件实现了我们的承诺,确保LEAP-1A发动机达到与我们的客户在CFM56产品系列中享受到的相同成熟度、耐久性和使用时间,”CFm国际公司的总裁兼首席执行官Gaël Méheust说道。

To ensure that the improvements would address durability challenges in harsh environments, CFM worked with a team of geologists to engineer dust that mimicked what engines experience in these environments around the world. Using a proprietary dust ingestion system, the company was able to replicate HPT blade wear that operators were seeing in the field. This innovative system allowed CFM to design, test, and validate improvements to increase the durability and time on wing of these parts.

为了确保改进能够解决恶劣环境中的耐久性挑战,CFm与一支地质学家团队合作,设计了模拟发动机在全球这些环境中所经历的灰尘。通过使用专业的灰尘摄入系统,公司能够复制运营商在现场看到的HPT叶片磨损。这一创新系统使CFm能够设计、测试和验证改进,以提高这些部件的耐久性和使用时间。

The CFM LEAP engine family delivers 15 to 20 percent lower fuel consumption and CO2 emissions, as well as a significant improvement in noise, compared to previous generation engines. With more than 3,500 LEAP-powered aircraft in service, the engine has allowed CFM customers to avoid more than 40 million tons of CO2 emissions.* The engine has been the most successful new product introduction in CFM's 50-year history, with the fastest ramp-up of engine flight hours ever in the industry – surpassing 60 million hours in eight years.

CFm LEAP发动机系列的燃油消耗和二氧化碳排放降低了15%至20%,与上一代发动机相比,噪音显著改善。超过3500架LEAP动力飞机投入使用,使CFm的客户避免排放超过4000万吨二氧化碳。*该发动机是CFM 50年历史上最成功的新产品推出,创造了行业内飞行小时数最快的增长,八年内超过6000万小时。

*Compared to the same flights powered by CFM56 engines.

*与CFM56发动机驱动的相同航班相比。
