Abstract

An effective aircraft carrier catapult, relates to a mechanism device for catapulting airplanes on aircraft carriers, belonging to the field of military technology, comprising a cylinder, a piston, and a pulley block, wherein the piston is connected to and synchronized with a movable pulley, both the movable pulleys and the fixed pulleys are provided in the amount of 2 to 8, among which a wire cable is wound for 4 to 16 times and then passed around a fixed pulley, finally fixed to a tow hook, thereby pulling a airplane to take up on a short deck.

Description

The efficient aircraft carrier ejector

Technical field:

The utility model relates to military technology equipment field and is specifically related to a kind of aircraft carrier ejector.

Technical background:

The fighting capacity of aircraft carrier mainly is by aircraft.More than 20～30 ton the aircraft of weighing is served the sky from the deck of 100m ± length, and best bet is to come afterburningly by the ejector on the aircraft carrier, and ejector has only the U.S. to make at present, complex structure and costliness, and English, method, Russia etc. all do not dare to inquire.One on American ejector bullet on 30 seconds daytimes, 45 seconds evenings, bullet was one, and ejection speed is slower; The heavy 100T of ejector body, weight is bigger; Bullet once consumes 1.5～2 tons of fresh water, and water consumption is too big.

Summary of the invention:

The utility model is that a kind of efficient aircraft carrier ejector will be provided, its simple structure, cheap and efficient, body is light, water-saving.

The purpose of this utility model is achieved in that allowing high pressure steam enter cylinder promotes piston and connecting rod, accelerated movement is made in pulling " movable pulley ", movable pulley and fixed pulley respectively have 2～8 pulleys, speed enlarged 4～16 times after steel cable was walked around movable and fixed pulley 4～16 times, reach at a high speed, by next " launching " aircraft of the hauling hook of steel cable end, aircraft accelerates to the predetermined speed rear towing hook and breaks away from automatically, by electric winch hauling hook and whole kinematic scheme are towed back to original position immediately, prepare next round.

Primary member steam cylinder piston of the present utility model, assembly pulley, hauling hook, winch all are prevailing articles for daily use (though the work that has particular design), and simple structure is cheap.Bigger except that cylinder on the weight, all the other members are heavy, only several kilograms of the hauling hooks of steel cable end.Total weight of the present utility model has only the part of present aircraft carrier ejector.

Water-saving is economized high pressure steam exactly, is economized the energy.Though power of the present utility model---cylinder and piston are the most ancient machinery, its efficient is jet-propelled much higher than youth but, and because of the gas that this latter sprays has at a high speed been taken away quite a few kinetic energy, but cylinder is fixed.In order to allow the potential energy of the high pressure steam in the cylinder as often as possible discharge, we only to the last period of piston motion stroke (for fighter plane only account for total kilometrage about 1/4th) for high pressure steam, piston is done uniformly accelerated motion, the back stops to send vapour for one section, allow the interior high pressure steam of cylinder expand and continue to promote the piston acting, piston is done varying accelerated motion.Calculating shows that the novel water consumption of this reality is compared with present aircraft carrier ejector, and it is especially little to seem, hour less than present 1/10, this is water only not, also comprises the energy, economizes big.

Description of drawings:

Concrete structure of the present utility model is provided by accompanying drawing.

Fig. 1 is the cutaway view according to the efficient aircraft carrier ejector that the utility model proposes.

Fig. 2 is the hauling hook cutaway view.

Fig. 3 is the cylinder cutaway view.

The specific embodiment:

This device comprises a cylinder main body (13), high pressure steam enters through electronic immediate action valve (10) and promotes piston (12) and connecting rod (17) accelerated movement left in the cylinder (13), the movable pulley (8) that is fixed on the connecting rod (17) with pin (18) also together links, the motion of slide block (9) is subjected to the restriction of slideway (not shown), and main purpose is to prevent connecting rod bend.Steel cable (3) is after walking around movable pulley (8) and fixed pulley (7) 4～16 times, and pulling force dwindles more than 4～16 times, and kinematic velocity but enlarges 4～16 times, and its multiple equals the sum of pulley.Steel cable continues to walk around to be decided after cunning (6) and (5) (also can only use pulley (5)), and its end is fixed on the hauling hook (2), and towing aircraft takes off, and the steel cable (3) on hauling hook this moment (2) is very little with the angle on deck, near parallel.

The connection of hauling hook (2) and aircraft is firm, and the angles because of the y direction of hauling hook (2) becomes one 100 degree～180 to spend with the fuselage line of travel draw more firm and more firm; And spring clamp is arranged inside the hauling hook (2), as long as guarantee to have hung up, can not fall by the weight of self.When the angle of the steel cable under the hauling hook and deck (4) increases to 15 degree when above, hauling hook (2) just can take off " hook " automatically, takes off.After the unhook, the electric winch (not shown) is towed back to original position by rope (1) with hauling hook (2) and whole movable parts, only waits hauling hook is hung up next airplane.

The running of cylinder (13): when aircraft breaks off relations, piston (12) enters surge chamber (15) brake, bounce-back more just in time left by exhausr port (14) steam discharge (having opened 1～4 openning on the steam drain), then the lower piston (12) that drags at winch returns and moves right, drain tap (11) is opened simultaneously, and when stroke also was left 1/5～1/20, drain tap (11) was closed, allow piston (12) buffering brake, arrive this, original position is all got back to by all mechanisms, waits for the instruction that next round " is launched ".

A seat (21) of hauling hook (2) is fixing aboard, tongue (20) is propping up on the seat (21) by pin (19) hinge knot, tongue (20) can be from down to swinging in the scope at fuselage rear, and the angle of vertical curve direction (during standard of fuselage) is between 10～90 degree.When steel cable was exerted oneself towing aircraft, angle was 10～20 degree; When hauling hook (2) breaks away from, tongue (20) bullet under the effect of spring (24) gets on, angle is 60～90 degree, jump ring (22) can guarantee hauling hook (2) under the gravity of self or big again two, three times power it is fallen down, if but steel cable (3) down or toward the fuselage rear when exerting oneself, hauling hook (2) is just can fall down easily.Inclined-plane (23) is 25～35 degree with the angle of tongue (20) axis, and the final work elastic force of jump ring (22) is 2～8kg.
