吸波导流体对某型涡扇发动机性能的影响

Impact of Guide Vane Used for Wave Absorber on Turbofan Engine Performance

进行了吸波导流体和发动机的联合试验,在进行进气流场畸变试验的基础上,建立了一个合理的联合试验方法和稳定性检测方法。通过对试验数据的计算分析,发现吸波导流体对发动机流场及性能的影响都很小。该试验对发动机隐身技术的研究提供了支持。

To study the influence of first vane made of unreflecting material on turbofan engine, a rational test method is proposed and realized and the test data are acquired. By analyzing the data, it is found that the influence is negligible. The test validates that the calculation is reasonable.
