发动机试车台的通道设计和噪声控制

Engine Test Cell Of The Channel Design And Noise Control

论述了航空活塞发动机试车台的气流通道设计,从气动力和流场出发保证发动机试车流场的均匀性和稳定性,同时对试车过程的噪声产生和所采用的噪声排除和隔音处理措施进行了阐述,对同类型的发动机试车台设计具有实际指导意义。

Discusses aviation piston engine test airflow channel design,from the aerodynamic flow field and ensures that the engine starting test flow field uniformity and stability,the noise generated on the testing process and the use of noise removal and treatment measures are described soundproofing,the same type of engine test stand design has practical significance.
