PRESSURE-DISTRIBUTION MEASUREMENTS ON THE TAIL SURFACES OF A ROTATING MODEL OF THE DESIGN BFW - M 31

摘要

In order to obtain insight into the flow conditions on tail surfaces of airplanes during spins, pressure-distribution measurements were performed on a rotating model of the design BFW - M 31. For the time being, the tests were made for only one angle of attack (a = 60°) and various angles of yaw and rudder angles. The results of these measurements are given;the construction of the model, and the test arrangement used are described. Measurements to be performed later and alterations planned in the test arrangement are pointed out.
