- Abstract
The problem of tailplane stall after aircraft icing( ice-contaminated tailplane stall) has posed a serious threat to flight safety. In order to research on the sensitivity of ice-contaminated tailplane stall thoroughly and establish an optimized flight test state matrix, flow field display technology has been applied for the first time in China to ice-contaminated tailplane stall flight test of an aircraft. Based on the flow field characteristics and load response during flight test, the tailplane stall characteristics and stall margin of the aircraft were studied. In addition, the tailplane stall characteristics of the aircraft with different ice types, flap defections and center of gravity were analyzed, and an optimized flight test state matrix was established. The results indicate that using flow field display technology can intuitively and effectively determine the sensitivity of ice-contaminated tailplane stall and the critical flight test state,which is of great significance for optimizing aircraft aerodynamic design and improving flight test efficiency.
