Description

Technical Field

[0001] The invention belongs to the technical field of ammunition launching, relates to grenade launching, and in particular to a variable-range multi-barrel grenade launcher. Background Art

[0002] Currently, the launchers for micro-personnel grenades, smoke bombs, and soft-kill ammunition carried by mobile armed platforms like military robots, tanks, and armored personnel carriers mostly utilize fixed-angle launch tubes and fire cartridge-loaded ammunition. Before firing, ammunition is loaded from the front or rear of the launch tube. During firing, a firing pin strikes a primer or transmits an electromagnetic signal to activate the induction primer, igniting the propellant and launching the warhead. After firing, the ammunition is reloaded. Existing launchers fire ammunition specifically designed for the platform they are carrying. The sheer variety of ammunition types creates a massive workload for military developers and places pressure on logistics support personnel during wartime and training exercises.

[0003] Moreover, the existing launchers have a fixed range and firing angle, and individual ammunition cannot be used, so it is naturally impossible to replenish it from individual ammunition. It requires a lot of manpower and material resources to develop and distribute special grenades of various calibers suitable for various purposes of the launchers. Moreover, since the optimal range and firing angle of grenades for different purposes are different, the maximum effectiveness of some purpose ammunition cannot be brought into play on the same launcher. Summary of the Invention

[0004] The purpose of the present invention is to provide a variable-range multi-barrel grenade launcher that can use individual ammunition as the warhead of the launcher and adjust the launch range and firing angle according to the purpose of the individual ammunition, thereby breaking through the technical limitations of traditional launchers and realizing new tactical requirements.

[0025] Before use, the launcher of the present invention is fixedly connected to a mobile vehicle via the base plate 10. The mobile vehicle can be a military robot, a tank, an armored vehicle, etc. First, the launch baffle 31 is loaded from the front end of the barrel 30 to the bottom of the barrel 30. Then, according to the task requirements, the safety pin of the grenade for the corresponding purpose is removed and the grenade is loaded from the front end of the barrel 30. The loading is completed when the base of the grenade is completely in contact with the launch baffle 31. Grenades for different purposes can be loaded into multiple launch tubes 3 respectively. Before launching, the user observes the battlefield environment information through the observation and aiming device 19, adjusts the direction of the launcher barrel 30 by controlling the first drive motor 131, and adjusts the elevation height of the launcher barrel 30 by controlling the second drive motor 141; when launching is required, according to the mission requirements and the type of ammunition to be launched, the chamber pressure is adjusted by controlling the electric push rod 40 to adjust the number of openings of the pressure relief holes 350, so as to adjust the range in conjunction with the elevation height of the barrel 30. The correspondence between the number of openings of the pressure relief holes 350, the elevation angle of the barrel 30 and the range is calculated by the algorithm embedded in the industrial computer. The user can directly adjust the range through the industrial computer. After adjusting the range, the device of the present invention can be controlled to launch grenades for corresponding purposes. The single-tube launch can be triggered by controlling the electric ignition head of a specified single-tube, or multiple electric ignition heads can be controlled to trigger multiple-tube simultaneous launch. After firing, control the electric push rod 40 to extend its stroke to the maximum, then remove the charging tube end cap 34 and the pressure relief pipe 35 as a whole from the thread on the front of the charging tube end cap 34, then remove the fired charging tube 33 from the thread on the rear of the barrel end cap 32, replace it with a new charging tube 33 with a good propellant seal, then install the charging tube end cap 34 and the pressure relief pipe 35 as a whole, and repeat the previous process of loading the launching partition 31 and the grenade for the corresponding purpose. After loading, it can be used again.

[0026] The launcher of the present invention can use grenades for various purposes of individual soldiers as warheads, fill the charging tube 33 with propellant to form a powder bag-type ammunition, and use an electric ignition head to ignite the propellant in the charging tube 33 to trigger the grenade launch; since the charging tube 33 is a steel tube with connecting threads at both ends and an ignition hole in the middle, the steel tube can be used after encapsulating the propellant and the electric ignition head. The structure is simple and easy to process. The propellant therein is a consumable item, and the charging tube 33 can be recycled and reused after use. The recycled charging tube 33 can be reused after re-encapsulating the propellant and the electric ignition head.

[0027] The launcher of the present invention is applicable to a wide range of ammunition sources. During actual combat or training, both vehicle-mounted grenades and grenades carried by individual soldiers can complement each other, thereby enhancing tactical flexibility and reducing the pressure of logistical supply.

[0028] The launcher of the present invention uses a fixed dose of propellant, and controls the number of pressure relief holes 350 on the pressure relief pipe 35 to be opened through the pressure relief device 4, thereby controlling the launch chamber pressure, thereby controlling the range of the launcher to meet the tactical needs of offensive grenades, defensive grenades, smoke bombs or other soft-kill grenades with different ranges, thereby maximizing the tactical effects of ammunition for various purposes.

[0029] The launcher of the present invention can also, according to tactical needs, continuously launch multiple grenades of different purposes to different distances within a few seconds by adjusting the launch chamber pressure to form a slow-moving barrage. For example, super-stink bombs, smoke bombs, and detonation bombs are first loaded into different launch tubes respectively. When launching, the super-stink bomb in the first launch tube is first launched to a distance of 80 meters, and then the stroke is quickly adjusted by the motor of the electric push rod 40. Then, the smoke bomb in the second launch tube is launched to a distance of 100 meters. Then, the stroke is quickly adjusted again by the motor of the electric push rod 40, and then the detonation bomb in the third launch tube is launched to a distance of 120 meters. This breaks through the technical limitations of traditional launchers and implements new tactical design.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
