Now there are two researching ways of the vehicle aerodynamics : testing and numerical analysis 迄今为止，国内外汽车空气动力学的研究一般是用试验和理论相结合、以试验为主计算为辅的方法。
2.
Research on the aerodynamic interaction between the rotors and components of rotorcraft have been a very important aspect and a very challenging subject in rotorcraft aerodynamics 旋翼干扰空气动力学问题一直是旋翼飞行器空气动力学的研究热点和难点之一。
