摘要： PROBLEM TO BE SOLVED: To obtain a firing system which can carry out firing with increased hitting probability by detecting an impact location of an artillery shell in the entire range in the vicinity of a target without having a blind, and highly accurately setting a correction amount of impact in the next firing. SOLUTION: A signal processor 14 is comprised of a video mapping processing circuit 25 and an impact location detecting circuit 26. The video mapping processing circuit 25 records the shape of a video signal from a receiver 13, divides the video signal into n-row ×m-colum cells, determines validity/ invalidity, based on a video area of each cell, and generates a video encoding signal obtained by synthesizing all the cells. The impact location detecting circuit 26 calculates a shift amount of the impact location, based on the video encoding signal from the video mapping processing circuit 25.

摘要： PROBLEM TO BE SOLVED: To achieve a greater depth in penetration by a method wherein a bullet core part provided in a bullet moves forward therein after the firing of the bullet so that the overall length of the bullet is larger than that of the bullet before the firing thereof to minimize the stress from an internal wall of a barrel as caused by balloting within the barrel. SOLUTION: A bullet core 1 is provided with a bullet core part 1a movable in a cylindrical outer cylinder 6 and a stopper 7 is formed on an internal wall at the tip of the outer cylinder 6. When a bullet equipped with the bullet core 1 is loaded into a barrel to be fired, a bullet core part 1a alone in the outer cylinder 6 of the bullet core 1 moves forward and the bullet core part 1a moved forward is stopped by the stopper 7 of the outer cylinder 6 so that the overall length L1 of the bullet core 1 in a state where a bullet is positioned in a barrel reaches L2 after firing doubling in its length. This can minimize the stress from an internal wall by ballotting within the barrel causing the bullet to elongate despite a short-sized type during the penetration thereof thereby achieving a greater depth in the penetration.

摘要： PURPOSE:To improve a launcher to be used when influence of a body is examined as a bird, for example, collides with or sucked to a windshield, a suction port of an aircraft. CONSTITUTION:A launcher has a pressure switching unit 1, a charger 2, a stopper 5 and a vessel for containing an object to be launched, and launches only the object to be launched and contained in the vessel. The vessel is formed of a light-weight buffer material. Covers as door type switching units are provided at the charger 2 and the stopper 5. A butterfly valve is provided in the unit 1. The weight of the vessel is reduced to improve speed performance. A vessel charging time is shortened by providing the covets, and its structure is simplified to reduce its manufacturing cost.

摘要： PURPOSE: To isolate a device charged with a liquid bursting charge from impact pressure waves generated in a combustion chamber, by making the liquid bursting charge to be made to flow in the combustion chamber from a supply chamber under a relatively low pressure, and providing a check valve which prevents the impact pressure waves from being fed back to a supplier at the time of firing. CONSTITUTION: Prior to firing, a differential valve 36 is maintained at an upper- half position by means of an external compression spring 210 connected to a rod 78 and the surface 66 of the head 62 of the valve 36 closes a radial internal cavity 126 so as to prevent a liquid bursting charge from flowing to the cavity 126 from a pump cavity 118. In the initial stage of firing, the liquid pressure in the pump cavity 118 rises and is communicated with a valve cavity 72. When the pressure applied to the rear surface of a washer 206 increases beyond the pressure applied to the front surface of the washer 206, the washer 206 is flattened and closes a passage 77 against the peculiar spring force of the washer 206 and intercepts a charging cavity 56 and a device in front of the cavity 56 from a ballistic fluid pressure which is generated at firing time.

摘要： PURPOSE: To quickly supply a cannonball by supporting a cannonball supply manipulator in a cardan ring rotatable on an outer periphery of a rocking frame of a gun barrel, and holding a positioner so as to slide and turn in a bearing assembly mounted on a vehicle. CONSTITUTION: A bullet supply manipulator 10 includes a bullet supply rockable arm 20 supported in a cardan ring 34 rotatable on an outer periphery of a rockable frame 30 in front of a trunnion shaft 14. For turning the bullet supply manipulator 10 there is disposed a joint 19 aligned on a coaxis 18 and facing each other putting the cardan ring therebetween. The joint 19 simultaneously supports a positioner 38 for determining a position relation between the bullet supply manipulator 10 and a bullet supply hatch 62 provided on a roof 42 of a vehicle. The positioner 38 includes a final end shaft 48 for axial movement and turning motion, and the final end shaft 48 is held in a bearing 44 at the end located far away from the cardan ring 34.

摘要： PURPOSE:To obtain a stable repulsion force and its offset force by providing a friction adjusting device which adjusts the friction forces between an outer launcher tube and a front inner-launcher tube of an inner launcher tube, and between the outer launcher tube and a rear inner launcher tube, and top and bottom covers which are respectively attached on the top and bottom of the outer launcher tube. CONSTITUTION:When a launching instruction is given to a flying object 25, and a rocket motor is ignited, a bottom cover 27 is blown off by a blast discharged from the rocket motor. Simultaneously, a rear inner-launcher tube 212 is pushed forward by the blast force, and breaks a top cover 26. When the flying object 25 gets out of an outer launcher tube 22, a front inner-launcher tube 211 is split into pieces and dispersed away from the flying object as it receives a circumferential direction wind pressure of the flying object 25. At this time, the change in the repulsion force exerted on a shooter is a plus direction repulsion force as shown on Fig. a, for example, during a period from t1 at which the blast of the rocket motor is started till t2 at which the top cover 26 is broken, and at the same time, a minus direction repulsion force is generated as shown on Fig. b during a period from t1 at which the blast is started till t2 at which the bottom cover 27 is broken, cancelling said plus direction reaction force.
