Abstract
In order to improve test data accuracy and acquire support interference characteristics, the test study on the support interference of wire-assistant sting support setting in Φ3.2m low speed wind tunnel is introduced. It is shown that, the impact of the beam of wire-assistant sting support on longitudinal aerodynamics characteristics of aircraft is small, and the stinghas great effect on longitudinal aerodynamics characteristics at high angle of attack. The yawing moment coefficients decrease and rolling moment coefficients increase at angle of attack from 0°to 15°with the existence of wire-assistant sting support. With the increase of side slip angle, the interference become bigger; without the vertical tail, the effect of the wire-assistant sting support on the pitching moment becomes small evidently.关键词
