Description

Grabbing net type carrier-based aircraft arresting device

Technical Field

The invention relates to a shipboard aircraft landing auxiliary device, in particular to a grabbing net type shipboard aircraft arresting device.

Background

In the existing technology, the arresting of the shipboard aircraft is mostly realized by adopting an arresting cable technology and through the hooking of a tail hook of the shipboard aircraft and the arresting cable. However, successful engagement of the tail hook with the arrester cord is associated with a number of factors, including: the hooking between the tail hook and the arresting cable is prone to errors due to landing opportunity, the speed per hour of the carrier-based aircraft, psychological factors of pilots, weather factors, visibility factors and the like, and therefore the successful hooking of the carrier-based aircraft cannot be guaranteed. If the tail hook of the carrier-based aircraft cannot successfully hook the arresting cable, arresting fails, if the tail hook is light, the pilot flies again to prepare for secondary arresting, and if the tail hook is heavy, the carrier-based aircraft crashes to crash or fails to fly again, and then the aircraft is damaged and people die.

The similar invention is mainly focused on the energy consumption aspect of the arresting cable after the carrier-based aircraft lands. The method includes but is not limited to energy dissipation by means of hydraulic pressure, turbine power, electromagnetic effect and the like, and the energy dissipation is carried out to enable the energy dissipation to drive the piston to move so as to carry out energy consumption and speed reduction, so that the speed reduction effect on the carrier-based aircraft sliding at a high speed is realized. However, if the tail hook is not hung with the arrester wire fixed with the ground after the carrier-based aircraft lands, the speed reducing device has no meaning.

Disclosure of Invention

Aiming at the technical problems, the invention provides a net-grabbing type carrier-based aircraft arresting device capable of carrying out secondary grabbing.

In order to achieve the purpose, the method is realized by the following technical scheme:

a net-grabbing type carrier-based aircraft arresting device, comprising: the aircraft carrier comprises two parallel slideways arranged on an aircraft carrier deck, a damper arranged below the slideways and an ejector arranged at the tail end of a carrier-based aircraft;

each slide way is provided with a sliding trolley which slides with the slide way, a barrier net is vertically fixed above each sliding trolley, and the extending direction of the barrier net is the same as that of the slide way;

ensuring that the vertical state interval of the arresting net meets the width required by the landing of the shipboard aircraft, wherein the length of the arresting net is determined according to the actual sliding energy consumption requirement of the berthing of the shipboard aircraft;

the arresting net is hinged at the upper end of the sliding trolley, a driving device for driving the arresting net to be vertical to the upper end surface of the sliding trolley from a flat laying state is arranged on the sliding trolley, and the sliding trolley is connected with the damper through a cable;

the ejector is capable of ejecting the barricade to the left side and the right side, the ejection head of the barricade is provided with a grapple, and the grapple is matched with meshes of the barricade net to be firmly grabbed.

By adopting the technical scheme, when the carrier-based aircraft is not landed, the arresting net is in a lodging state, when the carrier-based aircraft approaches the aircraft carrier, the arresting net is firstly changed into an upright state (under the drive of the sliding trolley driving device) from the lodging state, meanwhile, the carrier-based aircraft is prepared for ejecting the tail arresting cable, the monitoring radar on the carrier-based aircraft can measure the position suitable for ejecting the arresting cable, after the carrier-based aircraft is landed on the aircraft carrier, when the carrier-based aircraft slides over the arresting net, the feedback sensor returns an instruction, the ejector at the tail of the carrier-based aircraft ejects the arresting cable, and after the arresting cable is grabbed by the grabbing hook of the arresting cable, the two pieces of the arresting cable start to cooperate with the arresting work, if the arresting cable is not grabbed, the second-time hook throwing is started immediately, and the combination of the tail hook claw and the net surface can be ensured due. The arrester wire grapple grabs the arrester net and then drives the sliding trolley to slide on the slideway, and the sliding trolley is connected with the damper under the deck through the cable so as to be decelerated and landed by the carrier-based aircraft. And after the speed reduction and the falling of the carrier-based aircraft are finished, the arresting net can be withdrawn along the slideway and redeployed.

In conclusion, when the carrier-based aircraft lands on a ship, the grapple is ejected to the two horizontal sides and hooked with the arresting nets on the two sides of the runway to achieve the effect of deceleration and arresting. Different from the traditional arresting system which needs high precision, the slide way type arresting net has larger receiving area, can be combined with a tail hook claw ejected by a machine body more easily, can be ejected again at any time because the arresting net can synchronously slide along a slide way along with an airplane, obviously reduces failure and secondary re-flying rate, and ensures that a carrier-based airplane can safely and accurately land an aircraft carrier deck.
