The IAE V2500 is a two-shaft high-bypass turbofan engine built by International Aero Engines (IAE) which powers the Airbus A320 family, the McDonnell Douglas MD-90, and the Embraer C-390 Millennium. [2]

2024年10月23日 · Chromalloy’s latest hot-section part, an IAE V2500 second-stage high-pressure turbine (HPT) blade, has been approved by the FAA and sent to its first customer.

Technical training document on V2500 A1, A5, D5 turbofan engines. Covers mechanical arrangement, modules, systems, and control. For aerospace professionals.

The most likely explanation for this is the V2500’s two-stage HPT and associated higher blade replacement and repair costs. The V2500’s EGT margin retention and improved reliability through several modifications mean it should be able to maintain …

V2500-A5’s higher core airflow and EGT margins permit higher thrust ratings up to 31,600lbs, higher than the V2500-A1’s maximum permissible thrust of 24,800lbs. When the V2500-A5 is operating in de-rated mode at the same 24,800lbs thrust achieved by the V2500-A1 at ISA plus 15 degrees, the -A5 can still deliver this thrust even under ‘hot

2023年11月23日 · 涡轮机部分包括hpt和lpt模块。 HPT是一个两级涡轮机，驱动HPC和附件齿轮箱。 LPT是一个连接在HPT模块后法兰上的五级模块。

2021年7月21日 · The FAA is adopting a new airworthiness directive (AD) for certain International Aero Engines AG (IAE) V2500 model turbofan engines. This AD was prompted by a review of investigative findings from an event involving an uncontained failure of a high-pressure turbine (HPT) 1st-stage disk that...

2024年6月12日 · 美国联邦航空管理局 (FAA) 正在针对某些国际航空发动机公司 (IAE AG) 的 V2500 型发动机采用新的适航指令 (AD)。 此指令是在对国际航空发动机有限责任公司 (IAE LLC) 的 PW1127GA-JM 型发动机的一次事件进行分析后提出的，该发动机的高压压缩机 (HPC) 第 7 级整体叶片转子 (IBR-7) 分离导致起飞中止。 此指令要求对某些高压涡轮 (HPT) 第 1 级轮毂和 HPT 第 2 级轮毂进行角度超声波检查 (AUSI)，以查看是否有裂纹，并在必要时进行更换。 此指令 …

Unlike many engines with this configuration, the V2500 has a two-stage high pressure turbine (HPT) to extract more energy and so achieve a higher core. pressure ratio. This is coupled with a 10-stage high pressure compressor (HPC), and an …

On March 18, 2020 V16580 engine experienced an aborted take-off, a fracture of the High Pressure Turbine (HPT) stage 1 Hub and an uncontained event. The cause of fracture is an anomaly in the material. Recent findings require accelerated removal of …
