Each technical characteristic in the utility model, can be with combination of interactions under the premise of not conflicting conflict.

Fig. 1 is the overall structure diagram of the utility model ground effect vehicle one embodiment, and Fig. 2 is to implement shown in Fig. 1 The top view of example, Fig. 3 are the left view of Fig. 2, and with reference to Fig. 1~3, the coordinate system on figure is used as reference, ground effect vehicle packet Cabin 1, power device 2, a pair of of swept-back wing 3 and a pair of of canard 4 are included, further includes flight control system (not shown go out), canard 4 and sweepback The wing 3 is symmetrically connected to the two sides of cabin 1, and canard 4 is connected to the front end of cabin 1, and power device 2 is used to provide dynamic needed for flight Power, power device 2 are controlled by flight control system.It is bound directly using canard 4 and cabin 1, substantially increases structural strength, reduce simultaneously Construction weight, preposition canard 4 and 3 composite configuration of swept-back wing, it is ensured that the inherent balance stability of ground effect vehicle, to mention High pneumatic efficiency.

The inherent balance stability of cruise: inherent stability refers to that aircraft is giving the shape condition disturbed and without active control Under, it is automatically moved back to equilibrium state.The aerodynamic center of the stability of equilibrium condition requirement height of ground effect vehicle, which is located at, bows Before the aerodynamic center faced upward, while center of gravity is located near the aerodynamic center of height.The utility model is by preposition canard 4 with after The composite configuration for plunderring the wing 3, the aerodynamic center for realizing height are located at before the aerodynamic center of pitching, and position of centre of gravity is adjusted to high Near the aerodynamic center of degree, inherent balance stability during cruise is realized with this.

Cabin 1, power device 2, swept-back wing 3 and canard 4 are airflow design, can promote the aerodynamics effect of aircraft It answers.

Canard 4 includes canard ontology 41 and can exist relative to the elevator 42 of the rotation of canard ontology 41, the setting of elevator 42 The rear side of canard ontology 41, elevator 42 are controlled by flight control system, are moved independently of each other between elevator 42, and elevator 42 is passed through Rotate in same direction, realize ground effect vehicle along Y-axis pitch control.

Swept-back wing 3 has angle of sweep, including swept-back wing inner segment 31 and swept-back wing outer segment 32, swept-back wing inner segment 31 and cabin 1 Connection, swept-back wing outer segment 32 is connect with the outer of swept-back wing inner segment 31, and continues to extend along the extending direction of swept-back wing inner segment 31, Reduce flight resistance.

Specifically, swept-back wing inner segment 31 is inverted diherdral structure, ground effect can be substantially improved, to improve lifting capacity. Swept-back wing outer segment 32 is upper counterangle structure, can substantially increase roll angle when turning, to reduce turning radius, improves mobility Energy.

It is provided with rotatable aileron 33 in swept-back wing outer segment 32, is moved independently of each other between aileron 33, by flight control system Control movement realizes that ground effect vehicle is controlled along the rolling of X-axis by rotating backward for aileron 33.

Power device 2 is arranged in the rear end of cabin 1, including engine (not shown go out), propeller 21 and along propeller 21 Circumferentially around propeller cowling 22, engine (not shown go out) has flight control system control start and stop and positive and negative rotation, engine (not shown It drives propeller 21 to rotate out), is specifically included by the thrust that the rotation of propeller 21 provides in X direction with increasing flying speed The propeller 21 of pair of parellel setting, self-movement between propeller 21 are not interfere with each other；Propeller cowling 22 can increase spiral shell when taking off The thrust of paddle 21 is revolved, so as to shorten distance of taking off, while there can be protective action to propeller 21, improve the safety of propeller 21 Property.

The ground effect vehicle further includes the vertical fin 5 for being connected to 1 rear end of cabin, is provided with rotatable rudder on vertical fin 5 51, the rotation of rudder 51 is controlled by flight control system, poor by the rotation of rudder 51 and the thrust of propeller 21, realizes flight Device is controlled along the yaw of Z axis.

The working principle process of the utility model ground effect vehicle is following (by taking the water surface takes off as an example):

Water surface static process: as shown in figure 3, when this ground effect vehicle is still in the water surface, the bottom of cabin 1 and swept-back wing 3 Portion is contacted with the water surface.When the disturbance around X-axis occurs, the swept-back wing 3 of 1 left and right sides of cabin can make ground under the action of buoyancy Effect aircraft is restored to equilbrium position.Therefore, the utility model has static inherent stability.As shown in Fig. 2, two spirals The rotational speed difference of paddle 21 can produce the torque along Z axis, realize this ground effect vehicle in the case where the water surface is static along the rotation of Z axis with this.

Take-off process: as shown in Figure 1, flying speed is increased by the thrust of the rotation of propeller 21 offer in X direction, when Speed gradually increases, and swept-back wing 3 generates sufficiently large lift, and entire aircraft will be with surface deviation, to realize take-off process. The rotation direction of two propellers 21 guarantees flight on the contrary, for offsetting complete machine in the state of the equilibrium along the torque of X-axis and rotation Device steadily takes off.

Cruise process: this ground effect vehicle is no more than its 3 maximum chord length of swept-back wing from water surface elevation in cruise process 50%, by rotating in same direction for elevator 42, realize that aircraft along the pitch control of Y-axis, passes through the same reverse turn of aileron 33, reality Existing aircraft is controlled along the rolling of X-axis.It is poor by the rotation of rudder 51 and the thrust of propeller 21, realize aircraft along Z axis Yaw control.

Descent: closing 21 dynamical system of propeller by the control of elevator 42 makes 1 bottom elder generation of cabin and the water surface Contact, then in drop in water surface in a manner of gliding.

It above are only the preferred embodiment of the utility model, but the utility model is not restricted to the embodiment, be familiar with Those skilled in the art can also make a variety of equivalent deformation or replacement without departing from the spirit of the present invention, this Equivalent deformation or replacement are all included in the scope defined by the claims of the present application a bit.
