Abstract

The invention relates to an offshore takeoff method for an aircraft, in particular to an offshore takeoff method for a carrier-borne aircraft on a common ship. Before the carrier-borne aircraft takes off, an auxiliary sliding plate (1) covering front and rear wheels (2) of the aircraft are suspended on the front and rear wheels (2) and the front and rear wheels (2) extend out of wheel holes (3) formed in the auxiliary sliding plate (1); in the takeoff process, the aircraft takes the auxiliary sliding plate (1) to be started on a deck of the common ship and slide in an accelerating manner; when the running distance of the aircraft exceeds the length of the deck, the aircraft leaves the deck to enter the sea surface, the aircraft slides to the water surface at a suitable inclination angle, the auxiliary sliding plate (1) kicks water on the water surface and is bounced when the aircraft is in contact with the water surface, and the aircraft is separated from the water surface to be continuously accelerated; the aircraft is bounced and accelerated on the sea surface for once or repeatedly; when reaching the takeoff speed, the aircraft flies away from the sea surface; and after the aircraft takes off and enters a stable state, the auxiliary sliding plate (1) falls off and is recovered by the ship and the aircraft retracts an undercarriage and normally flies. The offshore takeoff method adopts the unique characteristic that the auxiliary sliding plate kicks water and is bounced on the sea surface, and realizes short-runway sliding takeoff of the carrier-borne aircraft on the common ship.

Description

The specific embodiment

Below in conjunction with accompanying drawing, further describe the present invention.

Before taking off:

On the front and rear wheel 2 of aircraft, hang an auxiliary slide 1 that covers two-wheeled, in the wheel hole 3 that front and rear wheel 2 is offered from auxiliary slide 1, expose;

In taking off:

1. aircraft, with auxiliary slide 1, starts accelerated slip on the deck on common naval vessel;

2. aircraft operating range enters sea over sailing out of deck after deck length, does not reach the lift that takes off, and aircraft slides to the water surface with an inclination angle, and when the contact water surface, auxiliary slide 1 is fetched water and upspring with the water surface, and aircraft departs from the water surface and continues acceleration;

3. aircraft is through the one or many acceleration of bouncing across the sea;

4. aircraft reaches takeoff speed and flies away from sea;

After taking off:

After taking off, enter stabilized conditions, auxiliary slide 1 is come off, by naval vessel, reclaimed, aircraft is packed up alighting gear and is entered normal flight state.

A kind of marine safety takeoff method of realizing ship-board aircraft on common naval vessel.This method is that the auxiliary slide that takes off is installed under undercarriage, aircraft is from slightly taking off on the deck at inclination angle with sea level, although aircraft is when leaving deck, also do not reach the required lift that takes off, but there is certain initial velocity, aircraft meeting and sea interact across the sea, utilize the auxiliary slide that takes off of aircraft, with the water surface phenomenon of fetching water, fetch water and can produce lift, make aircraft on the water surface, produce jump, if the digging angle of initial velocity and the water surface is suitable, aircraft can bounce, after once or for several times spring is accelerated, aircraft reaches takeoff speed, the realization lift-off of taking off.Aircraft is after realization is taken off, and the auxiliary slide that takes off that comes off, is reclaimed by naval vessel, and packs up alighting gear, enters normal flight pattern.

Certainly, the present invention is not suitable for taking off in having the weather of high sea, and needs aviator to have certain driving technique to be grasped.To unmanned aerial vehicle, need design automatic takeoff program.

Described auxiliary slide 1 is overlooked and is ellipticity, the length of aircraft that front and back length equals 0.5-0.8 times.Oval Sliding Resistance of Vehicle Slide is little, easily accelerates, and reaches spring object.The length of auxiliary slide 1 is long or too short is all unfavorable for that aircraft slides across the sea, accelerates, bounces, and the coming off and reclaim of auxiliary slide after the lift-off of being convenient to take off.

The distance of at least exposing 0.3 times of wheel diameter in the wheel hole 3 of offering from auxiliary slide 1 at described front and rear wheel 2.Distance described herein, the size that front and rear wheel 2 exposes, exposes too smallly, slides above deck, accelerates motion and be unreliable, easily wipes and touches deck.Expose too much, entering sea does not affect accelerated slip at sea, just will consider that the reliable in action that comes off of being convenient to after lift-off realizes.

In described taking off, an inclination angle is the angle horizontal by 10-30 degree, to obtain across the sea " spring ", different aircrafts are selected corresponding angle within the scope of this, obtain better effect.

Up to the present the deck running take off that board a plane in common naval vessel can't realize, reason is that common naval vessel does not have sufficiently long skid deck, the present invention has made up the problem of deck length deficiency, to sea, extend, the characteristic that adopts unique auxiliary slide to slide, bounce on sea, has realized the running take off of carrier-borne aircraft on common naval vessel.
