地效飞行器水面起飞滑跑距离估算方法

地效飞行器、水上飞机在水面起飞时,由于受到发动机推力、水动力和空气动力的作用,其运动规律非常复杂。加上阵风、水面状态以及驾驶员的操纵技术等一系列因素,使情况更加复杂化了。本文在基本运动方程中引入了机身浸湿面积与滑行速度成负斜率线性关系的假设,从而简化了起飞距离的计算过程,得到发动机推力与起飞滑行距离之间的关系曲线。本文...

The Estimated Method of the Takeoff Distance of a WIG on Water

When Wing in Ground Vehicles （WIG Vehicles）, Seaplane take off on water, the law of motion may be very complicated, because of the effect of propeller thrust, hydrodynamic force and the aerodynamic force. The situation may be more complicated, if considering the gust, surf, and the skill of the pilot. The assumption that the wetted area of the fuselage is negative proportional to the velocity is introduced in the kinematical equations. Accordingly, the computation of the takeoff distance is simplified, and the relational graph between the propeller thrust and the takeoff distance can be draw. The simplified method can be used to help selecting the engine model or to evaluate the takeoff distance.
