Abstract

Abstract:

The relationship between breakdown vortex and vertical tail buffeting is analyzed by experiment. The stimulation effects which the wake of breakdown vortex exerts on various modes of vertical tail buffeting are investigated in detail. The normal modes and natural frequencies of vertical tail model are calculated by numerical method firstly. Then, the vortex structure of delta wing at different angles of attack is recorded by laser sheet flow visualization technique at 30 m/s. The buffeting responses of vertical tail tip and root are measured by accelerometer. The oscillation velocity of the wake is measured using the hot-wire anemometer. The results show that the vertical tail buffeting originates from the breakdown vortex. The buffet boundary is related to the location and intensity of the vortex breakdown. The wake of the vortex resonates with the vertical tail and further reinforces the buffeting phenomenon. As a result, the buffeting frequencies are identical with natural frequencies of the tail structure. The broken-down vortex at relative low angles of attack generates high frequency vibration mode of the vertical tail whereas at high angles of attack gives rise to the low frequency vibration mode.

Key words: vertical tail buffeting, high angles of attack, leading edge vortex, buffeting acceleration, vibration mode
