| PURPOSE: To enable repetition of an ignition process for a charge of propellant, by injecting a liquid propellant less by a fixed amount than the total capacity of a combustion chamber into the combustion chamber so as to keep a specified size of an ullage capacity for adjusting combustion in the combustion chamber and a tube. CONSTITUTION: Initially, when dynamic injection is selected, about 70% of a liquid propellant is introduced leaving about 30% of ullage into a combustion chamber 16 through a propellant inlet 24 from a propellant source 24A. At this point, a propellant injector applies a spiral flow pattern turning by a centrifugal force centered on the axis core of a gun to the injected liquid propellant and a retained gas left in the ullage is moved axially on the flow pattern. The portion from an ignition gas source 26A to an ignition gas inlet 26 is turned to the tangential direction of the combustion chamber 16, and an ignition gas is sent into the combustion chamber 16 near the breech and begins to circulate along the inner circumferential surface from an end part on the side of the breech. A mixing is accomplished between the ignition gas, a byproduct gas generated from the combustion of the liquid propellant and a byproduct gas from an ignitor. COPYRIGHT: (C)1991,JPO | ||||||

| PURPOSE: To stabilize combustion by simultaneously combusting liquid propellant and carrier in a state that the propellant is immersed with porous flammable carrier in a propellant chamber. CONSTITUTION: This is a method of simultaneously combusting liquid propellant and carrier in a state that the propellant is immersed with porous flammable carrier in a propellant chamber. The flammable carrier to be used includes, for example, spongy cellulose, spongy polyurethane, fibrous cellulose, etc. The powder to be used includes, for example, mixture aqueous solution of oxidizer and a plurality of burning components by using hydroxyammonium nitrate as an oxidizer, and triethanolammonium nitrate, trimethylammonium nitrate, etc., as combustion components. Thus, an optimum igniting area and the quantity of the powder can be determined from the initial of burning to obtain stable combustion of the powder. COPYRIGHT: (C)1991,JPO&Japio | ||||||

| PURPOSE: To avoid strong feedback by performing additionally accelerating a mass integrating a traveling charge and a projectile through combustion of charged propellant and moving the mass forward along the cavity of barrel thereby performing controlled ignition and combustion. CONSTITUTION: A regeneration piston 34 is pushed forward by combustion gas generated in the rear combustion chamber 56 at the head thereof to push an initial propellant interposed between both heads. Consequently, the piston head separates from the conical face of head at the idle bottom to make an annular gap 56A and a stationary propellant flows through an injection port 56A into the chamber 56 thus sustaining or increasing the combustion gas pressure. When the pressure being applied to a moving propellant exceeds a propulsion starting level, the propellant and a projectile bring to accelerate while passing through a fixed center inclining face under influence of first stage liquid pressure of regeneration system.

| A projectile firing weapon (10) for firing artillery rounds (30) from a barrel assembly (11) utilises rounds having a projectile (31) and an associated bore seal (32) which is radially expanded by relative axial displacement between the projectile and the bore seal. The barrel assembly (11) provides a barrel bore (13), a barrel chamber (14) for the round to be fired and an associated breech chamber (15) for the next round to be fired. A propellant chamber (17) is formed between the barrel chamber (14) and the breech chamber (15). The breeched round (30) provides the closure for the barrel chamber (14) and after firing is advanced into the barrel chamber (17) by the next round introduced to the breech chamber (15). Liquid propellant may be injected to the propellant chamber (17) to facilitate rapid firing. | ||||||
