摘要
Abstract
An investigation on aerodynamic characteristics of internal weapons bay's door was conducted in high speed wind tunnel and the static/dynamic test results at Mach number equals to 0. 6 were presented in this paper. Static test results indicate that the acoustic noise around internal weapons bay's door is strong and the sound pressure level at the fore-edge of the door is close to the peak value of internal bay floor. Aerodynamic loads of the door change acutely with the variation of door's opening angle and that reach to the culmination when $ almost equals to 30? Dynamic test results show that aerodynamic loads of the door are influenced distinctly by St number. Aerodynamic characteristics have obvious difference between opening and closing process of the door.关键词
