Technical Field
The invention relates to the field of WIG craft, in particular to a high-efficiency WIG craft elevator counterweight device.
Background
WIG craft utilizes the ground effect principle to make a vessel. The WIG craft can be divided into two types, namely an hydrofoil craft and an air wing craft, wherein the hydrofoil craft consists of a hull for providing buoyancy and a horizontal stabilizing surface with a certain aspect ratio. The surface effect is generated by the influence of the surface on the airflow when the horizontal stabilizer moves close to the surface, so that the lift-drag ratio of the horizontal stabilizer is increased, the propelling power can be reduced, and the sailing away from the ground can be kept.
The elevators of the small WIG craft are the "control surfaces" that control the lifting of the WIG craft. The horizontal tail wing of the WIG craft can be manipulated, and the pitching motion of the WIG craft is mainly controlled. The elevator is movable up or down about the elevator rotation axis. The elevator of the original wing ship is not balanced, and can generate a declination effect under the action of the gravity of the elevator. And the downdip force is not on the elevator rotating shaft, so that the bolt of the elevator rotating shaft is loosened after a long time, and further the elevator is loosened. Due to the long-term stress of the elevator, the elevator control system is stressed for a long time, and the elevator control system is adversely affected.
Practical contents
The invention provides an efficient counterweight device for an elevator of a ground effect wing ship, which solves the problems that the elevator of the original wing ship in the prior art is not balanced and can generate a downward inclination effect under the action of the gravity of the elevator.

Furthermore, the balance weight is a shot connected to the middle part of the rotary rudder shaft through a connecting rod.
Furthermore, the counterweight is a disk-shaped weight with the center of the circle in the axial projection of the rotary rudder shaft.
Further, the counterweight is a regular polygon weight with a mass center in the axial projection of the steering shaft.
Furthermore, the outer side of the horizontal stabilizer is provided with an outer wing capable of rotating along with the balance block, the outer wing comprises a front wing and a rear wing, the middle part of the rear wing is rotatably connected with the horizontal stabilizer through a steering shaft, the far rear end of the front wing is rotatably connected with the horizontal stabilizer, a limiting rod is arranged in the rear wing, and a sliding rod rotatably connected with the limiting rod is arranged in the front wing.
Further, the limiting rod can slide in the rear wing.
Furthermore, the far rudder shaft side of the elevator is of a hollow structure

1. the invention can provide downward torque through the balance weight, thereby balancing the weight of the elevator, and the balance weight with the mass center in the steering shaft can adjust the whole mass center of the breeding system to be close to the steering shaft, thereby being convenient for the system to keep balance.
2. The invention belongs to the field of ground effect wing ships, and the flight height is lower, so that no matter the time of the elevator moving upwards or downwards is shorter, the horizontal flight attitude is kept to advance most of the time, when the elevator deflects, the balance block can drive the front wing and the rear wing to deflect, and at the moment, the rear wing of the front wing can be stressed in the direction opposite to the deflection direction of the balance block, and the auxiliary effect can be played when the elevator returns; or when the elevator or the steering shaft is loosened, the negative feedback rectification function can be realized, and the flight safety is ensured to a certain extent.
