摘要： PROBLEM TO BE SOLVED: To generate a high-pressure gas pulse appropriate for propelling a projectile in a gun barrel by evaporating a solid fuel and an oxidizer, and elevating the same to a high temperature by plasma to produce an exothermic chemical reaction. SOLUTION: Plasma flows in a direction perpendicular to electric discharges generated behind a projectile 30 in the axial direction 42 thereof, so that theprojectile 30 travels in a gun barrel 16. A propellant mass positioned to react with the plasma flow generated by the discharges reacts with the plasma generated by the discharges incident thereto to be converted into a high pressure gas for accelerating the projectile 30 in the gun barrel 16. The propellant mass includes a solid fuel and an oxidizer that do not react at ambient conditions, and a part of the fuel abuts an electric discharge structure 32. The fuel and oxidizer are vaporized and elevated to a sufficiently high temperature by the plasma to produce an exothermic chemical reaction. In this way, it is possible to produce a high-pressure gas pulse appropriate for propelling the projectile 30 in the gun barrel.

摘要： PURPOSE: To obtain a high additive efficiency of acceleration by breaking sealings of a metallic sealing structure and a water sealing structure, when a flight body is propelled in a cylinder, to cause alkali metal or alkaline earth metal to mix with water in the cylinder. CONSTITUTION: When a gas producing agent is initiated to produce a gas G1 such as hydrogen gas of high temperature and high pressure, a cap member 32 is pushed to accelerate a flight body 3 in a cylinder 1, so that when the flight body passes through a hollow portion of a metallic sealing structure 4, sealing of the structure is broken by shock and heat to lay open sodium 5. When the flight body 3 further advances to rush in a water sealing structure 6, sealing of the structure is broken to cause jetting of water 7 whereby the sodium 5 and water 7 are brought into contact with each other to produce chemical reaction, so that hydrogen gas G2 of high temperature and high pressure is produced rearwardly of the flight body 3. Pressure of the hydrogen gas G2 blows off the cap member 32 rearward and pushes the flight body 3 to provide further acceleration.

摘要： PURPOSE: To obtain a liquid bursting charge gun device having a differential piston coaxially provided with the discharging cavity of the gun in a chamber in the discharging direction, by providing an annular control valve and an annular differential piston which is inserted in such a way that the piston can move in a telescopic relation with the chamber of the discharging cavity. CONSTITUTION: A liquid bursting charge is moved to the front side of an annular section 40 and made to flow in a cavity 56 through an annular passage 44, to a cavity 116 through a passage 77, and to an internal cavity 74 by moving a valve backward by means of a spring 82 which pushes a rod 78 to one side by moving a cam 176 and retreating the surface 48 blocking a propellant supplying bore 156. When the cam 176 moves, a piston is separated from the valve and moved forward by the pressure of the bursting charge and the bursting charge flows in a pump cavity from the internal cavity 74. Then a bullet 26 is inserted into and locked in a bullet chamber 22 by means of a bolt 32, and the firing pin 32a of the bolt 32 gives a blow to the primer pouch 30a of the bullet 26. Consequently, the primer pouch 30a is ignited and ignites a booster 30b.

摘要： PURPOSE: To obtain a liquid bursting charge gun having a differential piston coaxially provided with the gun bore in the chamber there of, by providing an annular control valve and a differential piston journaled in such a way that the piston can move in a telescopic relation with the chamber of the discharging cavity. CONSTITUTION: A liquid bursting charge gun is constituted in such a way that the gun tube 10 of the gun is placed in the first cavity of a housing 14 and the closed second cavity 34 of the housing 14 which is coaxially provided with the longitudinal axis of the gun tube 10 is controlled by means of the housing 14. Then a piston sleeve 38 and a valve sleeve 36 are born so that the sleeves 38 and 36 may move relatively to each other and the valve sleeve 36 and gun tube 10 mutually control a liquid bursting charge supplying chamber 116 having a variable volume. In addition, the piston sleeve 38 and valve sleeve 36 mutually control a liquid bursting charge pumping chamber 118 having a variable volume. After the pumping chamber 118 is expanded to the maximum volume by a taken-in liquid bursting charge, the volume of the chamber 118 is reduced and third conduit means 62 and 142 are coupled with the chamber 118. Then the liquid bursting charge is injected into a bullet receiving chamber 22.

摘要： PURPOSE:To provide an impulsively supplying device for high pressure gas of which handling is facilitated and of which safety is high by a method wherein a rupture plate is explosively opened with a combustion gas pressure generated by an explosive combustion of combustion mixture gas and the combustion gas pressure is applied to a pressure receiving part of a device connected to the opening. CONSTITUTION:In a life saving rope injecting device, combustible mixture gas is filled in a pressure-proof container 1. While a burret 34 is filled in an injection cylinder 31, the combustible mixture gas is ignited by an igniter 6. With this ignition, the combustible mixture gas filled in the pressure-proof container 1 is explosively burst to break a breaking plate 2. With this breaking, the high pressure combustion gas within the pressure-proof container 1 is injected from the opening into the injection cylinder 31. The gas may act against the injection cylinder 31 to project the burret 34. The life saving rope 35 resiliently connected through an injection of the burret 34 can be expanded. Accordingly, it is possible to use it in place of the conventional type of energy source of powder and hydraulic oil and the like and the device can easily be handled.
