INSTALLATION FOR CHECKING OPERABILITY OF ACTUATING ELEMENTS OF MULTIPLE AMMUNITION Russian patent published in 2025 - IPC F42B35/00 G01M7/08 G01N3/313 

FIELD: testing; ammunition.

SUBSTANCE: invention relates to an installation for checking operability of actuating elements of a multiple ammunition. Installation comprises a tray-type base on which a shell with gas-dynamic models of the front, combat and bottom ammunition compartments is rigidly fixed. Besides, it comprises powder charges with igniter simulator and actuators. Gas-dynamic models of compartments and shell are rigidly attached to each other by means of semi-rings and threaded connections with support ring. Front and bottom compartments are equipped with powder charges. Charge of the front compartment is equipped with replaceable volume compensators, and is gas-dynamically connected to each other by means of peripheral slot channels passing in the zone of connection of semi-rings and ignition channels in the piston of the bottom compartment. Combat compartment comprises a size-weight models of a combat element equipped with a simulator of a parachute system and an explosive device, having gas-dynamic heat-receiving elements as actuators, which are triggered at the required levels of power and heat loads. In the cover of the front compartment there is a simulator of the ignition device and supply channels are made in the form of threaded holes, which are overlapped with the required number of plugs. Bottom compartment has a forcing unit simulator made in the form of a cover with thinning, overlapping the discharge opening of the bottom and breaking down at the pressure value corresponding to the minimum or maximum force of forcing the investigated ammunition. Simultaneously, the working cavities of the installation are located in the front, side and bottom compartments of the ammunition and are equipped with high-frequency pressure sensors and low-inertia coupled thermocouples, which provide the required accuracy of determining parameters inside the ammunition compartments.

EFFECT: reliable actuation of ammunition actuators, arming of combat elements and faultless operation of the developed structure.
