Abstract: 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.
