Description
Technical Field
The invention belongs to the technical field of emission, and particularly relates to a liquid jet balancing device aiming at gas ejection recoil.
Background
The ejection launching object has huge recoil, for a vertical launching system, the recoil can be directly counteracted due to the ground support, but for inclined launching, if no recoil balance measures are taken, strong impact load is brought, and a recoil supporting system, such as a recoil device and a hoe aid of an artillery, is necessarily provided, and the mass of the device is far greater than that of an elastomer, so that the device occupies a large proportion of the weight of the whole artillery.
The rear-seat-free gun accelerates the rear jet gas through the tail jet pipe and is reversely and backwardly seated by the gas, so that the gun tail is required to be provided with a jet pipe with larger size, the gun tail cannot be applied to multi-pipe emission, and the rear jet gas causes a certain threat to a rear area.
The rocket fuel gas catapulting generally uses high-pressure and low-pressure catapulting, the charge of the rocket fuel gas catapulting burns in a high-pressure chamber, fuel gas enters a low-pressure chamber through a spray pipe, the projectile moves under the pushing of low pressure, no recoil high-pressure and low-pressure launching has two schemes of parallel connection type and serial connection type, the serial connection type means that the high-pressure chamber is behind, the low-pressure chamber is in front, the low-pressure chamber is used for pushing the projectile, the high-pressure chamber is used for reversing recoil, the stability of the projectile is poor, the parallel connection type means that the high-pressure chamber is inside, the low-pressure chamber is outside, the low-pressure chamber is used for pushing the projectile and reversing recoil at the same time, and the stability of the projectile is good.
The high-low pressure emission has the problems of large drug loading amount, non-ideal front impact recoil balance of the emission, large and heavy size of the director, complex loading of the projectile and the high-low pressure catapult and the like, and serious overall incompatibility problem occurs. The backdrop-free transmitting device also has a scheme of depending on a backdrop balance weight, the scheme is difficult to block and throw, the weight of the balance weight is overlarge, and the direction finder is overlong, so that the overall compatibility difficulty of the transmitting device is increased.
The liquid balance body is applied to the recoilless cannon, but is mainly used for reducing tail flame, and the M4 type 'Karl-Gusttaff' recoilless cannon cartridge of the Sweden Saybofuss power company is additionally provided with the liquid balance body, so that fuel gas and liquid are mixed in the transmitting process, and the capability of balancing the recoilless is mainly borne by the fuel gas. The literature 'no recoil gun inner trajectory research based on a liquid balance body' (Cao Yongjie) designs a charging structure containing the liquid balance body, wherein the design is used for integrally blocking and throwing liquid only after ignition for a period of time, and the liquid is still sprayed out by a tail nozzle to balance recoil force, so that the liquid is not accelerated to block and throw, and the utilization rate of the liquid balance recoil force is not high.
In view of this, there is a need for a barrier balance device that has low overall mass and good overall compatibility.
