摘要
通过某型涡扇发动机与可移动插板式畸变发生器的联合试验 ,确定了对某型涡扇发动机进气压力畸变所作稳定性评定的内容、方法、技术和程序。研究了复杂进气流场的分布表示方法和畸变指数的计算分析方法。得到了被测发动机在若干工作状态下抗压力畸变能力的定量数据。可对我国发动机的使用、研制和发展提供支持和服务。
The method and experimental facility for assessing the pressure distortion of a certain turbofan engine are studied. A schematic diagram of the experimental facility is shown, which incorporates changes and additions. The features of the facility are described, among which the fluid-driven movable flashboard distortion generator and the pressure transducers can make transient state measurements. The experimental facility and procedure are used to investigate the distortion of complicated inlet flow field and distortion index. The investigation results show that the experimental facility and procedure can satisfy the needs for assessing pressure distortion of a certain turbofan engine.
