Function conversion device for bottom air spraying of ships and boats

Abstract

The invention provides a function conversion device for bottom air spraying of skimming boats, hovercraft and ground-effect wing ships. In order to achieve the goal, the function conversion device adopts the technical scheme that a plurality of air spraying openings capable of changing the air spraying direction are formed in the bottom of the skimming boats, the hovercraft or the ground-effect wing ships, and the airflow sprayed out from the air spraying openings is directionally sprayed out through an airflow steering plate. When the airflow is downwards sprayed out, the skimming boats, the hovercraft and the ground-effect wing ships realize the vertical ascending and descending; when the airflow is forwards or backwards sprayed out, the ships and the boats are driven to advance or retreat in an assisted way. Compared with the prior art, the function conversion device has the advantage that the skimming boats, the hovercraft or the ground-effect wing ships can directly ascend and descend from the water surface or the land. During the running on the water surface, the boat body is separated from the water through an air layer sprayed out from the boat bottom, the wave-making resistance is greatly reduced, and the friction resistance between the water and the boat body is eliminated. The ships and the boats are operated and controlled by an automatic control system, and the longitudinal balance and the transverse balance of the ships and the boats can be maintained by the respective independently acting airflow steering plates through regulating the air spraying angle in real time.

Description

technical field [0001] The invention relates to a function conversion device for jetting at the bottom of a boat, in particular, a function conversion device for controlling and assisting in driving a planing boat, a hovercraft and a wing-in-ground craft to lift and advance. Background technique [0002] Most of the high-speed boats on the surface are planing boats. When sailing at high speed, most of the bottom of the planing boat is above the water surface. The greatest resistance is the friction between the bottom surface of the planing boat and the water. Under the severe impact of the waves, and the waves appearing when sailing at high speed, its movement trajectory is clearly displayed on the radar, making it difficult to disappear. Although the hovercraft can sail in the air, the airbag apron is easily torn by the impact of water when sailing on the water surface; the airbag apron is easily torn by debris such as broken glass and stone chips when sailing on land.

Problems solved by technology

Although the wing-in-ground boat adopting the static air cushion technology can directly lift forward from a static state, the design, installation position and diversion design of the front ducted propeller are a major technical difficulty; the aerodynamic center and the center of the ship Inconsistency will lead to instability or even capsizing of the wing-in-ground effect ship. The static air cushion is used in the wing-in-ground effect ship, which is another technical difficulty in the design in terms of trimming
