Specific embodiment
The present invention will be further described with reference to the accompanying drawing.
It is a kind of improve aircushion vehicle and bow bury first bow Effuser device.It is mainly used in ship domain, being related to one kind can basis
Air cushion vehicle adjusts the angle between bow Effuser device spout and horizontal plane, under the conditions of the different speed of a ship or plane to improve air cushion
Ship bowing in high-speed cruising, which is buried, to be appeared for the first time as so that air cushion vehicle when running at high speed, by control device system, is adjusted
Save the angle between bow jet pipe spout and horizontal plane.It includes the components such as swivelling-nozzle, head, fixed jet pipe, wherein living
Dynamic device adjusts its working condition according to aircushion vehicle by control device system under the conditions of the different speed of a ship or plane: in aircushion vehicle is in
When lowsteaming, head is in compressive state, and bow jet pipe sprays high pressure gas according to aircushion vehicle difference Control requirements around
Body；When aircushion vehicle is in high speed operation, head is in bending stretch state, and bow jet pipe spout downward, sprays downwards high
It calms the anger body, bowing to bury so as to improve aircushion vehicle appears for the first time as increasing the maneuverability and safety of aircushion vehicle.
The bow jet pipe that existing air cushion vehicle uses can only rotate in fixed horizontal plane around vertical axes, be single-degree-of-freedom
Device bows the present invention provides a kind of improvement aircushion vehicle and buries first bow Effuser device.Bow jet pipe is adjusted in the bow Effuser device
Angle between spout and horizontal plane makes bow jet pipe that can not only spray pressure-air along peripheral direction under middle low-speed situations, obtains
