航空发动机整机防结冰试验能力综述

Overview of aero-engine ice testing capability

结冰对航空发动机性能有重要影响,在发动机研制与验证过程中必须开展整机防结冰试验。简要说明了飞行试验所存在的问题以及开展地面整机结冰试验的原因与必要性。重点介绍了美国NASA、AEDC,俄罗斯CIAM,英国NGTE和发动机OEM公司(GE、RR与PW)以及国内高空结冰试验台或露天结冰试验台的基本情况。结合航空发动机特点以及最新适航条款要求,针对中国开展高空或露天结冰试验能力建设所存在的主要挑战进行了梳理,并对中国高空或露天结冰试验能力的发展提出了展望。

Aero-engine icing and anti-icing test should be verified during the engine development and validation process due to the important influence of icing on engine.Problems associated with flight icing tests,as well as reasons and necessity for ground icing tests,were introduced briefly.This paper emphasized the bare facts of facilities,including those in the United States such as NASA and AEDC,Russia’s CIAM,the UK’s NGTE,and engine Original Equipment Manufacturer(OEM)companies(GE,RP and PW),as well as those in China.Combined with aeroengine characteristics and the latest airworthiness provisions requirements,main challenges in establishing highaltitude and outdoor icing test capabilities in China were analyzed systematically and future development were prospected.
