SUBSONIC FLUTTER TESTS OF AN UNSWEPT ALL-MOVABLE HORIZONTAL TAIL

Abstract

The results of subsonic wind tunnel flutter test on a dynamic model of an unswept all movable horizontal tail are presented. The test data show the variation of flutter speed with stabilizer rotational restraint for three positions of the rotational axis. In addition, the effect of free-play in the stabilizer actuating mechanism on the fluter speed is determined for one rotational frequency at one rotational axis position. Complete model data, including the measured zero airspeed coupled vibration frequencies and node lines, are included.
