A Realization Method of Caseless Automatic Weapon Using Liquid Propellant

Abstract

The invention discloses an achieving method of a cartridge-case-free automatic weapon adopting a liquid gun propellant. The weapon is driven by a stepping motor to achieve bullet filling and combustion chamber locking, and combustion chamber airtightness is achieved through a bullet and a fixed type plunger. Separated binary liquid gunpowder (oxidizing agent and combustion agent) is adopted as thegun propellant, a constant pressure adjuster is used for maintaining constant gun propellant ejection pressure, an electronic fire control unit (EFCU) is used for controlling the opening time of an electromagnetic valve so as to accurately control the ejection amount of mixed gun propellant, gunpowder ejection is completed through spraying holes in the plunger, and an electronic igniter is used for igniting the gun propellant to complete bullet launching. The weapon can easily achieve the functions of single launching, multiple launching, continuous launching and blank ammunition and rifle grenade launching; the launching power can be adjusted to achieve the optimal killing and wounding effect; an inner bullet channel can be actively corrected to ensure stability of an outer bullet channel; the shooting precision which is higher compared with bolt weapons can be achieved in the single launching mode, and continuous launching can be achieved for implementing fire control.

Description

technical field [0001] The present invention relates to technologies related to the development of software and hardware of weapons, gunpowder, electromechanical and embedded equipment, and in particular to technologies related to the automatic control of weapons, the use of liquid gunpowder and the realization of weapons without shells. Background technique [0002] The bullets used in today's firearms and small-caliber artillery are all packaged in the form of a bullet and a shell case, and the role of the shell case is indispensable. The shell plays the role of encapsulating the propellant powder, wrapping the warhead, fixing the primer, airtight the chamber, and taking away part of the heat to cool down. However, the bullet casings also bring great troubles, such as: copper bullet casings cause a great waste of resources; the weight of bullet casings accounts for more than half of the bullets, which limits the number of ammunition carried by soldiers; the need to eject c...

Problems solved by technology

In order to meet the needs of semi-automatic or fully automatic shooting, most modern firearms use the energy of gunpowder gas to realize shell ejection and loading. It is difficult to accurately use the energy of gunpowder gas to complete the next cycle in the design. In order to meet the requirements of reliability, It can only complete the shell ejection and re-entry loading action in a very violent way by excessive use of gas energy

This not only reduces the utilization efficiency of gunpowder, but also affects the accuracy of shooting.

Due to the limitations of the mechanical structure, it is difficult to meet the needs of fully automatic shooting and high-precision sniping on one gun. As a result, the current sniper rifles have to adopt a bolt-action structure or barely adopt a semi-automatic structure in order to meet the accuracy requirements.
