【摘要】 针对国内开展航空发动机吞鸟试验较少、试验方法尚不成熟、不规范等问题,从吞鸟试验标准条款要求入手,对比分析了GJB241A、GJB242A、GJB3727、CCAR33等标准规范在吞入的鸟的质量、数量、速度,以及鸟撞位置、发动机状态、试验程序等方面的差异。从试车台、抛鸟设备、测速装置、试验用嵌鸟弹壳等方面,提出了试验设备选择及研制方法。结合某型发动机吞鸟试验,确定了具体试验技术指标,研制了专用抛鸟试验设备,制定了吞鸟试验程序和方法。首次在发动机定型中开展了发动机吞鸟试验,获得了较为满意的试验效果,验证了试验技术指标确定、试验设备选择和研制方法的可行性和有效性,并在防护措施、抛鸟设备、应急预案、鸟撞击位置、吞鸟对发动机的影响等方面提出了建设性意见。更多还原

【Abstract】 Aiming at the problems of less bird ingestion test,immature test method and non-standard in China,the differences of GJB241 A、GJB 242 A、GJB 3727、CCAR33 in weight,quantity,speed,impact position,engine status and test procedure of bird ingestion test were compared and analyzed. The selection and development methods of test equipment were proposed from the aspects of test bench,bird throwing equipment,speed measuring device and bird shell. Combined with the bird ingestion test of a certain engine,the specific test technical indexes were determined,the special bird throwing test equipment was developed and the bird ingestion test procedures and methods were formulated. The bird ingestion test of the engine was carried out for the first time in the engine finalization,and the satisfactory test results were obtained,which verified the feasibility and effectiveness of the determination of test technical indexes,the selection of test equipment and the development method. Constructive suggestions were put forward on the effects of bird ingestion test on engine,protective measures,bird throwing equipment,emergency plan and collision location.更多还原
