摘　　要：测量新机试飞中的旋流及稳、动态压力畸变，即可全面评审进气道／发动机的相容性。根据进气道流场分析，建立一种适合于空中使用的旋流测量技术，并提出了解决问题的途径，介绍了τ８７，探测器的设计、性能、特点、试验结果。he measurement of swirl and the distortion of static-/transitional pressure in flight test of a new plane is used to evaluate the compatibility of inlet and engine. The purpose of the paper is to establish a technique for measurement of swirl in flight, and to put forward the approach for solving the problem. Also the design, performance and features of the detector τ87 and its experimental results are introdced in the paper.
