Abstract
A device for controlling discharge of ammunition units from the barrel of a gun in sequence with muzzle velocities within a large velocity range, enables simultaneous activation of the ammunition units on a target area. The device comprises a plurality of part charges having different predetermined compositions including sizes, types, powder varieties, powder dimensions, and being combinable into plurality of selected combinations defining total charges. A controlling device is provided for receiving information regarding the firing parameters and parameters influencing muzzle velocity including powder temperature of the part charges and pressure in the gun barrel and for calculating relevant velocities from the large range of velocities which allow for plurality of sequentially fired ammunition units to simultaneously arrive at the target area. Also selector devices are provided, responsive to the controlling device for selecting from the plurality of part charges, based on the calculated velocities, corresponding combinations of part charges to define the total charges for respective ammunition units which allow to achieve the calculated velocities with high accuracy.
