The present invention relates to the technical field of reducing recoil, and in particular to a dual-chamber device for controlling the area of a fire transmission channel and a gas guide. The device comprises a barrel, a movable dual-chamber, and a rear spray module. The present invention controls the unlocking of the movable block in the channel between the dual-chamber by introducing gunpowder gas from the front of the barrel, thereby increasing the area of the fire transmission channel at the appropriate time, producing a "small at first and small later" effect, so that a small amount of gunpowder gas flows from the rear chamber into the rear chamber in the early stage, while a large amount of gunpowder gas flows from the front chamber into the rear chamber in the later stage, thereby increasing the total mass of gunpowder gas sprayed from the side rear spray channel; at the same time, a section of a smaller cross-sectional area channel is provided in the rear spray pipe, thereby controlling the flow rate of the rear spray gas and extending the total rear spray time, ultimately achieving the purpose of increasing the total impulse of the gas rear spray and significantly reducing the recoil. The present invention can solve the problem that the area of the fire transmission channel in the current dual-chamber low-recoil firing method is immutable and the energy of the gunpowder gas in the front chamber cannot be fully utilized to reduce the recoil.
Description
Technical Field
The invention relates to the technical field of solid gunpowder emission and back-sitting reduction, in particular to an area air-guide control double-chamber device of a fire transmission channel.
Background
In the conventional barrel weapon firing process, the explosive gas will produce a significant recoil impulse and recoil while pushing the projectile into motion. The excessive recoil can lead to the failure of the shoulder-mounted firing of the high-power infantry carrying weapon, and also can lead to the severe jump or vibration of the vehicle and the helicopter carrying the small-caliber cannon, which can seriously restrict the loading of the high-power conventional weapon on advanced vehicles such as airplanes, ships, light wheeled vehicles and the like while influencing the firing precision. Thus, the problem of reduced recoil in barrel weapons directly affects the performance of conventional weapons, and is a key bottleneck technique for coordinating the contradiction between firearm power and maneuverability.
The dual-chamber emission structure is a newer squatting structure, and directly utilizes the gunpowder and gas energy in the rear chamber to carry out the post-spraying, thereby achieving the purpose of greatly reducing the squatting force. However, in the existing dual-chamber launching method, in order to prevent excessive powder gas in the rear chamber from flowing into the front chamber in the early stage of launching, the area of a fire transmission channel is generally small and unchangeable, so that the powder gas in the front chamber cannot flow into the rear chamber in time due to the small area of the fire transmission channel in the late stage of launching, a large amount of powder gas in the front chamber is wasted due to the fact that the powder gas follows a projectile to flow out of a chamber opening, the recoil impulse cannot be reduced by fully utilizing the powder gas energy in the rear chamber, and the energy utilization efficiency of the powder gas is low. Meanwhile, in order to inhibit the maximum pressure in the rear cavity, the sectional area of the rear spraying channel is generally larger and unchanged, so that the gunpowder gas in the rear cavity can be led in time to stabilize the maximum pressure peak value of the gunpowder gas, but the high-pressure gas is also led to have shorter rear spraying duration, and the total impulse of the rear spraying gas is not improved.
Disclosure of Invention
The invention aims to provide a low squatting launching technology with a controllable fire transfer channel and a small channel area, so as to realize a gas transfer channel area gas-guiding control double-chamber device with high gunpowder gas energy utilization rate, large total impulse of a post-jet body and continuous shooting.
The technical solution for realizing the purpose of the invention is as follows:
the dual-chamber device comprises a barrel, a movable dual-chamber and a back spraying module, wherein the movable dual-chamber is arranged in the barrel,
The movable double-chamber comprises a front chamber and a rear chamber, and the rear chamber is sleeved and fixed at the rear part of the front chamber;
The rear chamber is internally provided with a baffle plate for blocking an initial fire transmission hole of the movable block and an air guide channel of the rear spraying module;
when the pressure of the gas in the front cavity is increased to a certain value, the movable block is separated from the front cavity so as to enlarge the area of the fire transmission channel;
The movable double-chamber also comprises a pellet, the pellet is arranged in the front chamber, and both the front chamber and the rear chamber are filled with solid gunpowder;
The rear spraying module is arranged on the barrel and comprises a connecting block, a piston, a reset spring and a rear spraying pipe; the connecting block is internally provided with an air guide channel which is communicated with the inside of the rear cavity, the rear spray pipe is inserted into the connecting block and used for guiding out high-pressure gas in the rear cavity and spraying the high-pressure gas backwards from the side of the barrel, and the piston is arranged between the air guide channel and the rear spray pipe and can slide along the air guide channel and is used for controlling the opening and closing of the rear spray pipe;
The reset spring is arranged between the piston and the connecting block, when the pressure of the air guide channel is increased to a certain value, the piston slides, so that the rear spray pipe is communicated with the air guide channel, and gunpowder gas is sprayed out backwards.
Compared with the prior art, the invention has the remarkable advantages that:
(1) The invention can realize the accurate control of the area of the fire transmission channel, adopts the unlocking mode of leading high-pressure gas into the front part of the barrel to push the clamping shaft to move as the movable block, thereby realizing the effect of changing the fire transmission channel at proper time and generating 'small before big' of the channel area, leading a small amount of gunpowder gas in the early stage to flow into the back chamber from the back chamber, leading a large amount of gunpowder gas in the later stage to flow into the back chamber from the front chamber, improving the total quality of the gunpowder gas sprayed after the channel is sprayed from the side to the back, and improving the energy utilization rate of the gunpowder gas.
(2) According to the invention, the areas of two sides of the conical movable block are different, and when a certain pressure difference is generated between the front cavity and the rear cavity, the conical movable block is pushed into the rear cavity to increase the area of the fire transfer hole channel. The design realizes a simple and convenient structure of 'small before big' of the area of the fire transmission channel, and has the defect of difficult accurate control.
(3) The three-section design is carried out on the rear spray pipe channel, when gas flows into the second channel, the cross section area of the pipeline is reduced to prolong the rear spray time, and finally the spray is further accelerated through the expansion nozzle, so that the total impulse when gunpowder gas is sprayed backward is greatly improved, and the aim of greatly reducing the recoil and realizing micro-recoil emission is achieved.
