Abstract

Landing gear is a main source of the airframe noise, which is currently a focus of the aeroacoustic field. In order to study effects on the acoustic performance of the landing gear from different structure parameters, large-scale simplified landing gear model experiment was conducted in the 5.5m×4m aeroacoustic wind tunnel. In the experiment, five velocities were chosen in the range of 34m/s~75m/s. Acoustic measurement was carried out with free field microphones and a phase microphone array. The noise source location, component contribution and noise directivity of the model were analyzed, and the characteristics of landing gear noise under different wind speed were obtained. By controlling the structural parameters, the results show that landing gear height, wheel diameter, angle of attack, wheel number and wheel angle of attack make important effects on the characteristics of landing gear noise, while the effect of deflection angle within 8° is relatively weak.
