The invention not only realizes the application of the powder gas type anti-recoil device on an artillery with middle or large caliber, simplifies the structure of an artillery system, increases the device usage support performance, but also reduces powder gas amount consumed by the extraction, lightens the impacts to the internal ballistic trajectory performance, increases extraction effect, increases counter-recoil speed, and improves recoil resistance curve.
Description
One technical field
The invention belongs to the cannon structure technology, particularly a kind of gun powder gas type inverse recoil and air suction composite apparatus.
Two background technologies
At present among the overwhelming majority large caliber gun recoil mechanism by the fluid pressure type recoil brak, advance the typical recoil mechanism that governor and vapour-pressure type recuperator means are formed again.Along with the continuous variation of modern battlefield demand, the problems that this recoil mechanism exists are protruded day by day, as complex structure, volume weight is big, and it is slow to advance speed again, is working medium with recoil fluid and high-pressure sealed gas, leakage, gas leakage problem are serious, and the technical guarantee difficulty is big.
The gun powder gas type inverse recoil device is a kind of special recoil mechanism, and it is working medium with the powder gases, and simple in structure, volume weight is little, and it is fast to advance speed again.Obviously, the gun powder gas type inverse recoil device can overcome the above-mentioned problems that typical recoil mechanism exists well.But it also has significant disadvantages, as has ablation problem, has influenced the service life of device; From bore extension gas muzzle velocity and barrel intensity there is certain influence; Do not have the cannon positioning function, need special mechanism to carry out the cannon location.Therefore, the gun powder gas type inverse recoil device is not used widely at present.
Air extractor is the indispensable device that fixed armaments such as tank gun, self-propelled gun are used for discharging automatically remaining powder gases in the bore, has the problems such as the powder gases amount is big, the effect of bleeding is undesirable that consume.
Three summary of the invention
The object of the present invention is to provide a kind of gun powder gas type inverse recoil and air suction composite apparatus, this device is compound by function, promptly expands the function of air extractor, make it have the inverse recoil function, just can utilize same working medium, same device, the function of the realization inverse recoil and two aspects of bleeding.
The technical solution that realizes the object of the invention is: a kind of gun powder gas type inverse recoil and air suction composite apparatus, with the powder gases is working medium, the function of inverse recoil with two aspects of bleeding can be compound in one, promptly surround an air chamber by piston, gun barrel and cylindrical shell, form the air-cylinder type dynamic structure, in order to realize the inverse recoil function, this air chamber is a caisson simultaneously, this air chamber and with gun barrel in bore between be communicated with by first pore, the oblique gun muzzle direction of this first pore is in order to realize bleeding function.
Gun powder gas type inverse recoil of the present invention and air suction composite apparatus, when being used for multiple advance and bleed two kinds of function compound tenses, piston is fixedlyed connected with gun barrel, and cylindrical shell is fixedlyed connected with reel cage, thus indirect connection the between formation gun barrel and the reel cage; After ending in the gun barrel recoil, advance again under the effect of gun barrel powder pressure in air chamber; The recoil initial stage is inflated to air chamber by bore, advance again latter stage by air chamber to bore jet and with bore in remaining powder gases extract out from gun muzzle.
Gun powder gas type inverse recoil of the present invention and air suction composite apparatus move back when being used for staying, to advance and bleed three kinds of function compound tenses again, and piston is fixedlyed connected with reel cage, and cylindrical shell is fixedlyed connected with gun barrel, thus indirect connection the between formation gun barrel and the reel cage; The bore of air chamber and gun barrel also is communicated with by second pore, in this second pore the time-delay check valve is set, and overflow valve is set on cylindrical shell; In the process of recoil, when powder pressure was greater than limit value in the air chamber, powder gases flowed out by overflow valve, and is static following under the effect of gun barrel powder pressure in air chamber; After ending in the gun barrel recoil, advance again under the effect of gun barrel powder pressure in air chamber; The recoil initial stage, inflated to air chamber via first pore by bore, behind time-delay check valve delayed start-up, powder gases is inflated to air chamber by bore by second pore, recoil latter stage, by air chamber via first pore to bore jet and with bore in remaining powder gases extract out from gun muzzle.
The present invention compared with prior art, its remarkable advantage is: this device has not only been realized the application of gun powder gas type inverse recoil device on middle large caliber gun, simplified the artillery system structure, improved equipment operational support performance, also can reduce the powder gases amount of bleeding and being consumed, alleviate influence, improve the effect of bleeding internal ballistics attributes, improve and advance speed again, improve the recoil resistance curve.Be in particular in: (1) is used for this device fixed armament such as tank gun and realizes advancing and when bleeding function again: a, replaced existing vapour-pressure type recuperator means, thereby but overcome the shortcoming of vapour-pressure type recuperator means protection difference; B, recoil initial stage, pore finishes the back by cylindrical shell or piston closes in the aperture of air chamber end in inflation, until advancing latter stage again, when pore enters air chamber in the aperture of air chamber end, powder gases begin by air chamber via pore to bore jet and with bore in remaining powder gases extract out from gun muzzle, thereby played the effect that time-delay is bled, improved pumping efficiency greatly; C, simultaneously, powder gases answer energy into than big many of vapour-pressure type recuperator means energy, only need a small amount of powder gases to satisfy and advance functional requirement again, therefore, can reduce the powder gases consumption, effect and improve and advance speed again obtains better to bleed.(2) this device being used for the bigger cannon of recoil stroke such as seismic bombing realizes staying and moves back, advances and when bleeding function again: a, replaced existing fluid pressure type recoil brak and vapour-pressure type recuperator means, simplify system architecture greatly, but overcome the shortcoming of fluid pressure type recoil brak and vapour-pressure type recuperator means protection difference; B, since the device the effect of bleeding, can avoid the generation of flareback and alleviate the breech flue dust.In addition, also can improve and advance speed again.In a word, the gun powder gas type inverse recoil device utilizes same working medium, same device, has realized the function of the inverse recoil and two aspects of bleeding.
