Detailed Description
The invention is further described below with reference to the accompanying drawings.
The invention discloses a tandem wing ground effect ship, which improves the stability of a ship body under complex sea conditions, reduces the resistance of the water surface and has triphibious capability.
A tandem wing ground effect ship comprises a ship body 3, tandem wings 2 arranged on two sides of the ship body 3, a tail wing 4 arranged at the tail end of the ship body 3, side plates 5 arranged on two sides of the tandem wings 2, and two duct type propeller propellers 1 arranged on two sides of the front end of the ship body 3.
Wherein the hull 3 is the main framework and support of the tandem wing WIG craft. The number of the ducted propeller propellers is two, and the two ducted propeller propellers are respectively arranged on two sides of the front end of the ship body 3 and used for propelling the tandem wing WIG craft. Particularly, the air ducts of the two ducted propeller thrusters 1 face the front wings of the tandem wings 2 disposed on both sides of the hull 3, so that dynamic lift can be generated by thrust and wake generated by the ducts, and the dynamic lift of the tandem wing-in-ground effect ship can be improved.
The front wings and the rear wings of the tandem wings 2 arranged on the two sides of the ship body are arranged upwards and downwards to form a height difference. The purpose is to intentionally accelerate the airflow on the upper surface of the rear wing by utilizing the downwash airflow of the front wing, thereby enhancing the lift force of the rear wing. Compared with the lower arrangement of the front wing and the upper arrangement of the rear wing, the lower washing airflow of the front wing can not cause adverse effect on the rear wing; compared with the upper wing and the lower wing, the front wing and the rear wing both generate positive lift force, and the center is positioned between the two wings, so that the balance during flight is easily maintained while the lift force is provided, and the balancing resistance is avoided.
Meanwhile, when the ship is cruising on the water surface, the rear wing can serve as a wave pressing plate, a relatively closed space is formed by matching with the side plate 5, and an air cavity is formed between the lower end of the serial wing 2 and the water surface by the airflow generated by the ducted propeller 1 arranged at the bow part, so that the ship has a very deep significance for low-resistance cushion lifting and severe sea-air lifting.
The hull 3 and the side plates 5 form a structure similar to a multi-hull ship, and have better hydrodynamic characteristics and stability. The stability is further improved by a tail vane rudder arranged on the tail wing 4 of the stern part.
The tandem wing ground effect ship provided by the invention combines the high-speed planing boat, the ground effect wings, the side plates and other mechanisms, so that triphibious navigation becomes possible. The invention fully utilizes the structural characteristics of the ship body, reasonably arranges and utilizes the air layer resistance reduction technology, and is matched with the broken steps and the relatively closed ship bottom, so that the air layer stably exists, and the water surface resistance is greatly reduced; the air duct of the ducted propeller is opposite to the front wing of the tandem wing, and the thrust and the wake generated by the duct are utilized to generate power lift, so that the dynamic lift of the tandem wing-in-ground effect ship is improved; the front wing and the rear wing of the tandem wing are arranged on the upper portion and the lower portion to form a height difference, downwash airflow of the front wing is accelerated by airflow on the upper surface of the rear wing, the lift force of the rear wing is enhanced, the front wing and the rear wing both generate positive lift force, the center of the front wing and the rear wing is located between the two wings, the balance during flying is maintained while the lift force is generated, and trimming resistance is avoided.
