A METHOD TO ACHIEVE THE CASELESS AMMUNITION FIRING WITH LIQUID PROPELLANT FOR AUTOMATIC WEAPONS

摘要

The present invention proposed a method to achieve the caseless ammunition firing with liquid propellant for automatic weapons. The weapons with this method were driven by a servo motor that led a slider for linear reciprocating motion, and then the slider drove the combustion chamber and rotary lock to complete the projectile loading and combustion chamber locking. The combustion chamber locking was done with the help of fixed plunger. A separated binary liquid gunpowder (oxidizer and fuel) was used as a propellant. The constant liquid propellant injection pressure was maintained by a constant pressure regulator; and electronic fire control unit (EFCU) precisely controlled the solenoid valve opening time in order to control the injection amount of the mixture. The gunpowder was injected through the nozzle on the fixed plunger, and was ignited by an electronic igniter to launch the projectile. The application of electronic fire control unit (EFCU) made the weapon can easily realize single fire, burst fire, fully automatic fire, as well as blank ammunition or grenades launching. It can adjust the injection quantity of propellant to achieve the optimal killing effect against the objectives in different distance with different protection level; in order to ensure the stability of the outer trajectory, temperature, humidity and pressure sensors can be installed to make internal ballistic correction; comparing with the bolt-action weapons, by using the firearms with such technology can achieve better shooting accuracy and continuous firepower suppression simultaneously.
