METHOD AND DEVICE FOR TESTS OF MINE LAUNCHER SHOT Russian patent published in 2004 - IPC

FIELD: military equipment, in particular, methods for tests of mine launcher shots and their assemblies and components. SUBSTANCE: the method consists in fastening of the mine launcher barrel on a support, loading of the barrel with a shot with a propellant charge, firing and check-up of the parameters of functioning of the shot and the propellant charge, in addition, the law of pressure variation in the chamber of the mine launcher barrel and the functioning of the shot assemblies and components at the initial trajectory leg are checked, on completion of the check operations, catching of the shot and its components is accomplished, the barrel of an artillery or tank gun is used as a support for attachment of the mine launcher barrel, and firing is conducted at elevation angles of the mine launcher barrel close to zero. The method of tests is realized with the aid of a device for tests of the mine launcher shot including the mine launcher barrel, fitting for attachment of the barrel on a support, firing mechanism with a safety catch and a check-out system, in which the support is made in the form of a barrel of an artillery or tank gun set at an elevation angle close to zero, the fitting for attachment of the mine launcher barrel on a support is made in the form of a threaded adapter combining the barrels of the mine launcher and the gun in alignment with each other, the firing mechanism is made in the form of a piston-striker positioned in a cavity made in the threaded adapter and whose space behind the piston is gas-dynamically coupled to an explosive charge, the safety catch is made in the form of a spring engageable with the piston-striker and a detachable pin entering the groove of the piston-striker and fixing it in the longitudinal direction, and the check-out system has a pressure transducer installed on the threaded adapter, gas-dynamically coupled to the chamber of the mine launcher barrel and electrically via a matching-amplifying device- to a recorder, as well as means for recording the shot parameters installed along and in the trajectory of the initial leg of shot motion, a catcher of the shot and its components is installed in the trajectory past them in the direction of shot motion. EFFECT: provided natural firing in the conditions of a confined space of firing paths of test stations, and enhanced quality and efficiency of follow-up of the mine launcher shot and its assemblies and components in the initial trajectory leg. 2 cl, 3 dwg
