When the ground effect vehicle landing water surface, wave can arrive the several times of own wt greatly to the impulsive force of ground effect vehicle.As Fig. 3, shown in Figure 8, hydrodynamic load is to the impact of ground effect vehicle structure when slowing down water, and the fuselage bottom at full machine center of gravity place is provided with hydroskis device 16.The hydroskis device is made up of hydroskis 20, the pressurized strut 21 of two bufferings and some rubber pneumatic bags 22.Rubber pneumatic bag plays buffering and the sealing function of avoiding the two direct contact between airframe structure and hydroskis structure.When hydroskis 20 touches water, buffering pressurized strut 21 absorbs the hydrodynamic impact load that hydroskis 20 is subjected to come in apace, in the floating condition after the ground effect vehicle landing, buffering pressurized strut 21 slowly releases energy stored again, has so just alleviated the impact of hydrodynamic load to structure widely.Hydroskis 20 profiles are similar to the very little water skiing flat board of width.Hydroskis 20 to be adjusted to fixed angle when water, make its even water.Hydroskis 20 profiles mainly act near the pillar that connects buffering pressurized strut 21 hydrodynamic impact load, keep simultaneously aircraft at hydroskis 20 water rear body and dividing plate 14 coast period that do not touch water as yet stably navigate by water, and make fuselage and dividing plate 14 bottom planing surfaces equably water.Hydroskis 20 earlier water also delayed the time that dividing plate 14 and fuselage touch water, reduced the water speed that touches of dividing plate 14 and fuselage, reduced the impact of hydrodynamic load.
Actual mechanical process of the present invention is achieved in that special-purpose visitor, goods buoy for both harbour that ground effect vehicle rests in similar airport finish on visitor, the goods behind the machine, starts cruising engine 13, slides to takeoff point.Slide in the process, " thrust is poor " control of available left and right driving engine is turned.At first special-purpose taxiway takes off in the bay.If bay taxiway curtailment or condition do not allow, also can slide the position of special delimitation and take off to the off-lying sea.In the process of sliding, thruseer 12 is driven and preheating, and hydroskis 20 is in the stowed position.After beginning to take off, cruising engine 13 and thruseer 12 are all driven to maximum rating.Simultaneously, wing flap 4 deflects down, and thruseer 12 spouts turn to, and jet cutting car flow is guided under the wing with the generation lift that hovers.When ground effect vehicle accelerates to get away speed, body carries away the water surface.After finishing the transition flight state, thruseer 12 cuts out, and wing flap 4 is packed up, and changes the average flight state in the ground effect height over to.
At ground effect vehicle from flying to the whole transition flight stage that changes cruising flight over to, chaufeur turns to the hydraulic sterring engine of spout, wing flap 4 and elevating rudder 11 to implement harmonious synchronous operation by fly-by-wire to thruseer 12, can make ground effect vehicle successfully carry out the transition to average flight state from takeoff condition, whole process operation is easy, reliable.
Under normal average flight state, three cruising engines 13 are all worked.When a cruising engine fault, can continue flight by two cruising engines.If stormy waves occurs, can replenish and start one or two thruseer 12 that always is in autorotation.When two cruising engine successive failures, can a cruising engine and two thruseers continuation flights.
In flight course, if meet obstacle, ground effect vehicle ground effect region to the 150 meter height clear an obstacle that flies out of can climbing.
After arriving the destination, put down wing flap 4, ground effect vehicle slows down, and puts down hydroskis 20 simultaneously.When aircraft speed is being reduced to water speed, hydroskis 20 at first clashes into the water surface, absorbs jolt capacity, and body does not progressively have in the entry, is entering neatly row order section.After hydroskis 20 touched water, wing flap 4 was promptly progressively packed up, and enters idling rating by cruising engine 13 aircraft is slided to the floating landing stage of berthing.
Ground effect vehicle of the present invention can make lift increase, resistance reduce in the aerial stabilized flight of adjoined water surface.Its maximum take-off weight can reach 390 tons, passenger capacity 500 people, cruising speed is 500 kilometers/hour, be can landing under high 2.5～3.5 meters sea conditions of wave the passenger-cargo ground effect vehicle in large-scale sea.
