中文摘要: 中国民航规章《航空发动机适航规定》CCAR 33.78要求,航空发动机吸入雨水和吸雹后不发生熄火 或喘振，没有不可接受的机械损伤和功率或推力损失。本文对遭遇雨和雹之后对航空发动机的影响进行了 分析，同时对发动机吸雨和吸雹后的试验判据进行了研究，对3%持续功率/推力损失和10%功率/推力退化 的实质内涵进行了分析并给出了明确的定义。在对国外型号的认可审查中，FAA及EASA局方接受了本文所提出的功率/推力损失和功率/推力退化定义，并完善了符合性证据。
Abstract:According to China Civil Aviation Regulations Airworthiness Standards : Aircraft Engines 33. 78, aircraft engines shall be capable of acceptable operation throughout its specified operating envelope. After ingestion of rain and hail, each engine shall not be flame out or surge, and there is no unacceptable mechanical damage, unacceptable power or thrust loss, or other adverse engine anomalies. The impact of ingestion of rain in aircraft engines is investigated first, and then the test criteria are also analyzed and investigated. The 3% sustained power or thrust loss and 10% power or thrust degradation are identified. During the validation of type certification of foreign engines, the above identifications are accepted by FAA and EASA. Some specific compliance data is created and submitted.
