飞机飞行过程中马赫数变化会对飞机气动产生很大影响,本文利用某大型水陆两栖飞机外形参数以及部分风洞试验值。通过飞机设计手册气动分册的方法计算变马赫数下的的升力特性,并对结果进行修正,使其更接近真实值。
The change of Mach number in aircraft flight will greatly affect the aerodynamics of aircraft. In this paper, the shape parameters of some large amphibious aircraft and some wind tunnel test values are used. Calculate the lift characteristics under variable Mach number through the method of the air book of the aircraft design manual and revise the result to be closer to the true value.
