EXPERIMENTAL STUDY OF AN ANGLE-OF-ATTACK VANE MOUNTED AHEAD OF THE NOSE OF AN AIRPLANE FOR USE AS A SENSING DEVICE FOR AN ACCELERATION ALLEVIATOR

摘要

An investigation was made to determine the ability of a vane mounted ahead of the nose of an airplane to give an indication of the average angle of attack over the entire wing span during flight through rough air. These tests were performed to determine the suitability of such a vane as a sensing device for an acceleration alleviator. The results show that the vane gives a sufficiently accurate measure of the average angle of attack over the wing span to be of use for this purpose, though rapid fluctuations in angle of attack caused by small-scale turbulence would have to be filtered from its output.
