Description

A kind of ship-board aircraft buffer-type method for arresting and stop formation

Technical field

The application designs airplane structural design technology, specifically a kind of ship-board aircraft buffer-type method for arresting and blocks knot Structure.

Background technique

During ship-board aircraft warship, the process success or not of blocking is directly related to the safety of aircraft, and arrester hook is Wherein the most key component.Existing arrester hook is mainly made of upper hook rod, lower hook rod and gib head three parts, and the three parts are logical Cross connection component connection.Upper hook rod is connected to airframe, and lower hook rod is connected to upper hook rod, and gib head is connected to lower hook rod, becomes One complete arrester hook.For aircraft in warship, gib head hangs on warship vizard plate fixed check cable, then by lower hook rod and Upper hook rod forms one powerful resistance to aircraft, to make to be down to zero in the aircraft taxi speed short time and shut down.Due to mesh Upper hook rod, upper hook rod and the gib head of preceding arrester hook are all integral pieces, pass through between part and hingedly connect together, so that entirely blocking Hook is hindered almost without retractility, and rigidity is especially big, in moment the active force on arrester hook can be transmitted to airframe, to rising to the bait The Structural strength calls of bar and fuselage join domain are especially high, so that structural fatigue performance is bad at this, can even lead when serious Cause structural failure, and then cause aircraft warship failure.It is to reduce arrester hook to the impact force of aircraft, mostly concerned patent is, A kind of buffering off-load arrester hook hook arm 201310611967.9.

Summary of the invention

Present invention is designed to provide a kind of ship-board aircraft buffer-type method for arresting and stop formation.Pass through improvement The structure type of arrester hook increases first-level buffer structure, by the active force pair on arrester hook between arrester hook and airframe The influence of airframe mechanism minimizes.

A kind of ship-board aircraft buffer-type method for arresting containing the stop formation connecting with aircraft body and is located at warship body deck On check cable, which is characterized in that the stop formation contain block bar, buffer and under block bar, it is described on block The upper end of resistance bar is connect with airframe, and the lower end and buffer ontology upper end for above blocking bar are connected as one, described slow Rushing device ontology is a rigid cavity, and the buffer medium and a damper piston of air-fuel mixture, buffering are equipped in rigid chamber body Piston is equipped with buffer medium through hole, and the piston rod of upper end and buffering piston that bar is blocked under described is hinged, described Under block bar lower end be equipped with and the matched hook of check cable；When aircraft landing, the hook that bar lower end is blocked under hooks warship Check cable on body deck, the shock loading of check cable block bar under passing through and pass to buffer, so that buffer is absorbed impact and carry Lotus realizes that ship-board aircraft buffer-type blocks.

Buffer ontology upper end is equipped with sealing cover, and sealing cover is equipped with buffer medium inlet, which is situated between Matter inlet is the structure of an included sealing.

The beneficial effects of the present application are as follows: 1) by blocked by bar and under block buffer between bar so that blocking Movement have pooling feature, ship-board aircraft can be allowed softer in warship, at the same reduce to airframe with above block The impact of the join domain structure of bar, so that its longer life expectancy.2) by adjust buffer damping, can to different aircrafts into Row targeted design.3) present invention is air-fuel mixture medium in the buffer medium of buffer, and advantage has: buffer is high-efficient, More impact energys can be absorbed；Operation and Maintenance is simple, each aircraft after warship blocks, operated without personnel, buffering piston The effect that can use oil-air pressure difference returns to initial position, it is automatic for next time warship block and be ready.

Attached drawing is described in further detail the application with reference to embodiments.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of ship-board aircraft buffer-type stop formation.

Fig. 2 is the schematic diagram of the section structure of ship-board aircraft buffer-type stop formation.

Explanation is numbered in figure: being blocked on 1 and is blocked bar, 6 hooks, 7 companies under bar, 2 buffers, 3 piston rods, 4 connection components, 5 Spindle, 8 buffer medium inlets, 9 sealing covers, 10 damper pistons, 11 through holes, 12 rigid cavitys, 13 seal assemblies

Specific embodiment

Referring to the ship-board aircraft buffer-type method for arresting that attached drawing, the application propose, blocked containing what is connect with aircraft body Structure and the check cable being located on warship body deck, the stop formation contain block bar 1, buffer 2 and under block bar 5, The upper end that bar 1 is blocked on described is connect with airframe, and the lower end and 2 ontology upper end of buffer for above blocking bar 1 are connected as one Body structure, 2 ontology of buffer are a rigid cavitys 12, buffer medium in rigid cavity 12 equipped with air-fuel mixture and One damper piston 10, damper piston 10 are equipped with buffer medium through hole 11, upper end and the buffer of bar 5 are blocked under described The piston rod 3 of damper piston is hinged by connection component 4, passes through seal assembly between piston rod 3 and the rigid cavity of buffer 13 are tightly connected, and the lower end that bar 5 is blocked under described, which is equipped with, passes through connector 7 under with the matched hook 6 of check cable, hook 6 The lower end for blocking bar 5 is fixed；When aircraft landing, the hook 6 that 5 lower end of bar is blocked under hooks check cable on warship body deck, The shock loading of check cable blocks bar 5 and passes to buffer 2 under passing through, buffer is made to absorb shock loading, realizes ship-board aircraft Buffer-type blocks.

Under when blocking bar 5 and being impacted, impact force blocks bar 5 and pushes 10 compression buffer rigidity cavity of damper piston under making The buffer medium of oil-gas mixture in 12 above damper piston, oil-gas mixture composition absorbs shock loading, effectively reduces Damage of the shock loading to airframe；After power is blocked in releasing, damper piston 10 is pushed by the high-pressure oil gas mixed liquor of top, band Bar 5 is blocked under dynamic to automatically reset.In design, by adjusting the size of through hole 11 on damper piston 10, buffer damping is realized Adjusting, can to different aircrafts carry out targeted design.

In implementation, buffer ontology upper end is equipped with sealing cover 9, and sealing cover is equipped with buffer medium inlet 12, which is the structure of an included sealing.
