Abstract
The utility model relates to a sleeve type piston tube for an ejector. The sleeve type piston tube comprises a section of piston rube formed by three sleeves, and slide rails, wherein the three sleeves have different diameters, and are coaxially sleeved together, and multiple sections of piston tubes are connected end to end to form the sleeve type piston tube; and the slide rails support multiple sections of piston tubes and are densely provided with a plurality of bearings. The sleeve type piston tube is characterized in that a piston ring is arranged between an inner sleeve and a middle sleeve for sealing, and a back slide stop of the inner sleeve and a front slide stop of the middle sleeve cling to each other to prevent the inner sleeve from fully sliding out of the middle sleeve, in the same way, a piston ring is also arranged between the middle sleeve and an outer sleeve for sealing, and a back slide stop of the middle sleeve and a front slide stop of the outer sleeve cling to each other to prevent the middle sleeve from fully sliding out of the outer sleeve; and bearings at the upper sides of the slide rails support all slide claws of the inner sleeve, the middle sleeve and the outer sleeve to support the whole sleeve type piston tube.
Description
Technical field
The present invention relates to the sleeve-type piston tube for ejector, be applicable to the catapult-launching gear of aircraft carrier-based aircraft launching catapult, belong to the science and techniques of defence field
.
Background technology
The ejector that aircraft carrier-based aircraft takes off is the proprietary technology of the U.S., although " Liaoning number " of China does not adopt ejector, but ejector takes off and can save a large amount of oil plants, thereby can not only strengthen the carrying capacity of carrier-borne aircraft, but also can increase the voyage of carrier-borne aircraft, therefore, the thinking of development shipborne aircraft catapult is forever there is no mistake, the part of ejector most critical is catapult-launching gear, because only possess the device of the most powerful ejecting function, carrier-borne aircraft could be launched away, what the U.S. was used is the steam ejection device, and the benefit of this device maximum is the steam that can produce high thrust, but produces the equipment of large steam and the power of consumption is very large, and China " Liaoning number " employing is that the sliding formula of jumping of Muscovite 8 degree is taken off, this efficiency of taking off is low, and takeoff speed is slow, and it is more unfavorable in operation, can to embody, United States Navy has researched and developed multiple ejector, comprise: the Series Pneumatic rotating disc type ejectors such as A, P series gunpowder rotating disc type ejector, F series inertial flywheel ejector, H Series Hydraulic mechanical type ejector, the jet light-duty ejector of J series, M series combustion and steam ejector, C series fluting cylinder ejector, Deng seven generation product, just last they think best or maximum steam fluting cylinder ejector of use now, so they are kept absolutely secret technique, other countries do not dare to inquire yet, I think that the road of China development should be that a kind of between the U.S. and Russia utilizes a kind of easier ejector to carry out the ejection type cunning to jump up and fly, because so can utilize the 8 degree gradients on deck, can manufacture light-duty catapult-assisted takeoff again, light-duty ejector claimed structure is simple, take up room little, stable performance, thrust is moderate, starting is fast, energy consumption is little does not have the characteristics such as energy consumption while preferably not taking off, the present invention is exactly that science and techniques of defence expert to China provides a kind of catapult-launching gear for the ship aircraft carrier shipborne aircraft catapult that possesses above characteristics.
Summary of the invention
The purpose of this invention is to provide a kind of light-duty, simple in structure, little, stable performance of taking up room, thrust is moderate, starting is fast, energy consumption is little and there is no the piston tube of the sleeve-type for ejector of energy consumption when not taking off.
