Description

Ground effect wing ship with electric adjustment sheet

Technical Field

The utility model relates to a ground effect wing ship makes technical field, especially indicates a ground effect wing ship with electric adjustment piece.

Background

The left wing and the right wing of the ground effect wing ship are provided with two aileron control surfaces, and the ailerons without electric adjusting pieces can generate unsafe hidden troubles. The WIG craft was equipped with two propeller piston engines on the continental United states TSIO-550-E23B, since the direction of rotation of the two propeller piston engines was in the right direction of rotation. The power and the maximum rotating speed of the piston engines of the two propellers are equal in the takeoff process of the WIG craft, the rotating directions of the two propellers are from one to the right, so that the WIG craft can generate a torsion force rotating to the right when flying, namely the WIG craft rolls transversely, and the WIG craft can roll and fly without timely pressing a steering wheel to the left by a pilot. In order to solve the problem of right transverse rolling, a pilot needs to press the steering wheel leftwards, the left aileron faces upwards, airflow blows the left aileron, the left wing has downward pressure, and the lift force of the left wing is reduced. The right aileron faces downwards, airflow blows to the right aileron, the lift force of the right wing is increased, the lift force balance of the left wing and the right wing can be changed, and the wing ship flies in a balanced state. If the pilot presses the steering wheel to the left all the time during the flight, the flight consumes a great deal of physical strength of the pilot and is unsafe hidden trouble during the flight.

The rear edge of the vertical tail wing is provided with a rudder which is not provided with an electric adjusting sheet, and when the ground effect craft glides or flies, the ground effect craft can generate heading right-rotating sideslip flight because the rotating directions of the two propeller piston engines are inclined to the right. The power and the maximum rotating speed of piston engines of two propellers are equal when the WIG craft slides or flies, and the rotating directions of the two propellers are all right, so the WIG craft slides or flies, a phenomenon of sideslip rightwards can be generated, a pilot pedals a left rudder to overcome the right sideslip flight fault, airflow blows the rudder surface of the rudder, the stern wing of the wing deflects rightwards under the action of the airflow, and the nose deflects leftwards, so that the longitudinal balance flight of the WIG craft can be kept. The pilot always pedals the left rudder to fly, so that the flight also consumes a large amount of physical power of the pilot, and the flight is unsafe.

The rear edge of the horizontal tail wing is provided with two elevators, and the elevators are not provided with electric adjusting sheets. The function of the electric elevator adjustment sheet of the horizontal tail wing is to enable the ground effect wing ship to fly in a longitudinal attitude state, and the electric elevator adjustment sheet can change the head raising moment and the head lowering moment of the wing ship in flying. If the loading of goods by the WIG craft is unreasonable, if the center of gravity of the WIG craft is deviated, the WIG craft can generate a head-up flying moment in flight, a pilot needs to push a steering wheel forward to fly, the steering wheel pushes forward, a control surface of an elevator faces downward, and under the action of airflow, wings at the tail of the wing are upward, and a nose is downward to keep the WIG craft flying in balance. If the ground effect wing ship loads cargo unreasonably and the center of gravity is deviated forward, the wing ship generates a head-down flying moment during flying, and a pilot pulls a steering wheel backwards to fly so as to keep the balance of the wing ship. Both the head-up and the head-down of the wing boat create unsafe factors for flight.

However, the adjustment plates are driven by hydraulic or pneumatic methods, which are not suitable for the rudder, so the adjustment plates are not installed on the rudder, and the hydraulic or pneumatic control method cannot accurately control the adjustment amount of the adjustment plates.
