摘要
发动机的空中启动能力是飞行安全的重要保障。根据发动机定型试飞的要求,飞行试验时,需要分别对发动机空中热启动和空中冷启动能力进行验证。本文通过对发动机停车后工作特性的研究,找到验证发动机冷启动和热启动能力的试验方法,为发动机空中停车后的处置措施提供了技术依据,保障了试飞的安全进行。
The air-start ability for an aero-engine is the guarantee to flight safety for aircraft.Ac-cording to the request of the evaluation and validation flight,verification of hot start and cold start ability should take place during the flight test.The operating characteristics of an engine in-flight shutdown are analyzed,and the test method for hot start and cold start is presented.The test method provides the basis for disposal measures while engine in-flight shutdown,and guaran-tees the flight safety for the flight test.
