A tandem wing-connected wing ground effect aircraft comprises a fuselage, front wings, rear wings, connected wings, engines, empennages and buoys. The height position relation between the front wing and the rear wing meets the condition that the ratio of the water surface distance of the front wing to the average pneumatic chord length of the front wing in the cruising state is equal to the ratio of the water surface distance of the rear wing to the average pneumatic chord length of the rear wing; the front-back position relation of the front wings and the rear wings meets the condition that the ratio of the front-back distance from the average aerodynamic chord focus of the front wings to the gravity center of the aircraft to the front-back distance from the average aerodynamic chord focus of the rear wings to the gravity center of the aircraft is equal to the square of the ratio of the average aerodynamic chord length of the rear wings to the average aerodynamic chord length of the front wings. By reasonably configuring the height position relation and the front-back position relation of the front wing and the rear wing, the longitudinal operation stability characteristic of the whole aircraft is enhanced, the technical problem that the aircraft is easily out of control due to additional pitching moment increment generated when the flight height of the ground effect aircraft with the traditional layout changes is solved, and the lateral maneuverability of the whole aircraft is greatly enhanced; the carrying capacity is improved, and higher carrying efficiency is achieved.

    一种串列翼‑连翼地效飞行器,包括机身、前翼、后翼、连翼、发动机、尾翼和浮筒;前后翼的高度位置关系满足:巡航状态下前翼的离水面高度与前翼的平均气动弦长的比值等于后翼的离水面高度与后翼的平均气动弦长的比值;前后翼的前后位置关系满足:前翼的平均气动弦焦点距飞行器重心的前后距离与后翼的平均气动弦焦点距飞行器重心的前后距离的比值等于后翼的平均气动弦长与前翼的平均气动弦长的比值的平方。本发明通过合理配置前后翼的高度位置关系和前后位置关系,增强了全机纵向操稳特性,解决了传统布局地效飞行器飞行高度变化时产生附加俯仰力矩增量导致飞行器容易失控的技术难题,极大增强了全机横航向机动性,提高了运载能力,实现了更高的运载效率。
