摘　　要：采用数值计算手段研究了嵌入机翼式升力风扇安装位置及风扇轴指向角度对机翼气动性能的影响规律。研究表明,当风扇位于机翼前部时,造成机翼流场大面积回流,气流流动紊乱,气动性能变差,但是升力风扇安装位置对进口畸变的影响程度不大,因此,升力风扇安装于机翼后部较好;当风扇存在倾斜角后,风扇提供的力矢量化,风扇不但提供升力还提供一定的推力,随着风扇倾斜角的增大,风扇提供的升力逐渐降低,推力逐渐增大,而机翼的阻力逐渐降低;随着风扇倾斜角的增大,气流偏转角逐渐减小,进气畸变显著衰减。The influence of the installation position and the angle of the fan shaft on the aerodynamic performance of wing were studied using the numerical calculation.The results show that when the fan is located in the front of the wing,the flow field of the wing will be backflow in a large area,the air flow will be disturbed,and the aerodynamic performance will be deteriorated.Moreover,the installation position of the fan has little influence on the fan inlet distortion,so it is better to install the lift fan at the rear of the wing.When the inclination angle of the fan exists,the force provided by the fan is vectorized,and the fan provides not only lift but also thrust.With the increase of the inclination angle of the fan,the lift provided by the fan gradually decreases,the thrust gradually increases,and the drag of the wing gradually decreases.With the increase of fan inclination angle,the airflow deflection angle decreases gradually,and the intake air distortion decreases significantly.
