介绍地效飞机带螺旋桨动力模型的风洞试验结果 ,着重介绍地面效应和螺旋桨转速参数对飞机气动力特性的影响。测量结果表明 ,地面效应非常明显 ,飞机升力和纵向稳定性都有明显增加。螺旋桨转速增加 ,使飞机升力增加 ,阻力减小 ,从而使升阻比有较大增加 。
In this paper, the result of wind tunnel test for a powered ground effect plane model with propeller was introduced. The influence of ground effect and rotative velocity of the propeller on aerodynamic properties of this plane was also presented. Test data demonstrate that ground effect evidently strengthens plane's lift and longitudinal stability. As the rotative velocity of propeller adds, the lift adds and the drag goes down. So the lift to drag ratio is enhanced greatly, also, the longitudinal stability of the plane is decreased a little.
