| 摘要 | 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 |
