METHODS FOR DETERMINATION OF CLOSE GROUPING OF FIRE OF MULTIPLE LAUNCHER Russian patent published in 2000 - IPC

FIELD: weapon, applicable at tests of multiple launchers. SUBSTANCE: the method consists in the test of the launcher with measurement of the parameter determining the close grouping of fire and comparison of it with the standard value of the parameter. The launcher is tested on a test bench, a force is applied to the bank of the launcher guides corresponding to the nature of action to the force acting on the guide bank at a salvo; the frequency of natural oscillations of the bank of the launcher guides is measured as the parameter determining the close grouping of fire. The frequency corresponding to the frequency spectrum of natural oscillations of the bank of the launcher guides of the same standard size satisfying the preset close grouping of fire at a salvo is taken as the standard value of the parameter. EFFECT: reduced time and cost of determination of close grouping of fire. 3 cl, 1 ex
