Embodiment Construction

[0031] Multi-purpose small full lift transport patrol boat. As shown in Figure 1, in order to meet the tactical requirements of fast maneuverability and flexibility, the patrol boat is equipped with an attitude control mechanism. It comprises auxiliary airbags 2 and 3 on the left and starboard sides, auxiliary airbag filling and deflation valves, 4 and 5, an air storage tank 6 and an air pump 7. When the boat turned left and sailed, the control handle 10 tilted to the left, and the electric control system started the starboard auxiliary airbag inflation valve 5 to inflate the starboard auxiliary airbag 3 rapidly. The starboard side raises the hull 1 and leans left, with an inclination of about 0-10 degrees. On the contrary, when the boat turned right and sailed, the control handle 10 tilted to the right, and the electric control system started the port side auxiliary air bag inflation valve 4 to inflate the port side auxiliary air bag 2 rapidly. Raising the hull 1 on the por...

Abstract

The invention provides a posture control mechanism for a small amphibious air-cushion vehicle. The small amphibious air-cushion vehicle has poor controllabitity (namely large turning radius and crosswind drifting) in the processes of turning in high-speed navigation and resisting the crosswind; and in a simple and feasible method for improving the controllabitity, an own posture is changed to achieve balance. According to the posture operation mechanism for the small amphibious air-cushion vehicle provided by the invention, an auxiliary airbag is connected between a vehicle body and an airbag at each one of both sides of the air-cushion vehicle, and the auxiliary airbag at one side is inflated, so that the auxiliary airbag is expanded. Thus, the vehicle body at one side is lifted, and the vehicle body is transversely and laterally inclined, so as to change the own posture. The posture operation mechanism has actual effects of improving the controllabitity and reducing the turning radius.

Description

Technical field: [0001] The invention relates to a small full-cushion lift hovercraft. Especially the attitude control mechanism to improve the navigation maneuverability. Background technique: [0002] The speed of small full-cushion hovercraft is generally in the range of 60-100Km / h. Its maneuverability during navigation mainly depends on the rudder behind the air propeller, which shows poor maneuverability when turning at high speed and resisting crosswinds (that is, large turning radius and drifting in crosswinds). Foreign large-scale full-cushion lift hovercrafts add a steerable side thrust air cylinder on the hull, which can effectively overcome the above-mentioned defects. However, the small-sized full-cushion lift hovercraft has a small power of the power plant, so it is impossible to set the side blowing device. Therefore, the maneuverability can only be improved by changing the posture of the hovercraft. There are many ways to change the posture of the hovercraf...
