TELEMETRIC PROJECTILE Russian patent published in 2020 - IPC F42B12/00 F42B15/01 

FIELD: weapons.

SUBSTANCE: invention relates to controlled projectiles with contactless operation at specified flight distance, set by external radiation source, which are used for research purposes during development of new types of ammunition and improvement of standard. Telemetric small-calibre artillery shell is equipped with a driving band and a nose fairing. It comprises receiving device of control signals through permeable bottom channel, printed-circuit board as a part of multichannel microcontroller, analogue-digital converter electrically connected with reserve power supply, measuring sensor, and investigated object built in standard chamber of housing. All units are filled with curing electrical compound. Power supply is arranged in head fairing which annular belt is based on thread in support to open end of housing. Power supply is connected to microcontroller via electric connector. It is rigidly connected to the investigated object in the form of a bottom fuse combined with an analogue-to-digital converter screwed together with the housing. At that, in diametrically located slots of the cover of the microcontroller are geometrically closed by congruent projections of end face of its shell of different profile. Microcontroller has electrical switching connector with stationary reading device. Telemetric unit sensor in the printed circuit board structure is a mechanical load meter. Bottom channel is optically transparent. Cover with microcontroller is rigidly connected by crank stopper.

EFFECT: technical result is higher reliability of device at all stages of its operation.
