DEVICE FOR CONTACTLESS PROGRAMMING OF TIME FUZES OF SHELLS OF SALVO-FIRE JET-PROPELLED SYSTEMS Russian patent published in 2004 - IPC

FIELD: military equipment, in particular, devices for programming of time fuzes.

SUBSTANCE: the device has a control unit, signal monitoring unit and a programming signal conditioner, use is made of an information exchange unit by a series interface, whose input and output are connected to the launching equipment of the fighting vehicle, decoder, simulator of the device for transmission of information, and a switch gear. The control unit is realized on a programmable microprocessor with a built-in timer, permanent and on-line storages with a program at which the duration of the programming signals at the input of each device of information transmission is deriberately lower of the fixed rate of fire. The signal monitoring unit is realized on a comparator. A modulator is introduced in the programming signal conditioner, the oscillator, modulator, power amplifier and the comparator are series-connected. A decoder, multiplexer, switch gear cubicles of the guides and an additional cubicle are introduced in the switch gear. Each cubicle is realized on a series-connected transistor gate and a controllable switch, for example, on a high-power field-effect transistor, thyristor, electromagnetic relay with make contacts. The outputs of the switch gear cubicles of the guides are connected to the inputs of the devices for transmission of information installed on each guide of the fighting vehicle. The output of the additional cubicle is connected to the input of the simulator-an equivalent of the device for transmission of information. The generator of the programming signal conditioner is made with a frequency corresponding to the resonance frequency of the devices for transmission of information.

EFFECT: provided normalization of signals for contactless programming of fuzes in the automatic mode of fire at a fixed rate of fire from loaded fighting vehicles of salvo-fire jet-propelled systems.
