PROJECTILE FUSE WITH OPTICAL TARGET SENSOR Russian patent published in 2024 - IPC F42C13/02 

FIELD: weapons.

SUBSTANCE: invention relates to weapons, namely to projectile fuse with optical target sensor. Projectile fuse with an optical target sensor, in the housing of which there is a safety-cocking mechanism, a power supply, a detonator, an optical target sensor with receiving-emitting channels. Each channel contains an electronic unit and a pulsed laser diode and a photodiode connected to it. Radiation axis of the pulsed laser diode and the optical axis of the photodiode are directed at different angles to the longitudinal axis of the projectile fuse. Plane perpendicular to the plane of the p-n-junction of the pulsed laser diode is parallel to the longitudinal axis of the projectile fuse. Electronic units of receiving-emitting channels are made in the form of a single electronic unit connected to a safety-cocking mechanism. Angle between the axis of radiation of the pulsed laser diode and the longitudinal axis of the projectile fuse in the direction of movement is in range of 60° up to 80°. Photodiode is displaced from the pulsed laser diode in the plane passing through the axis of the optical unit and the axis of radiation of the pulsed laser diode, into the wide part of the fuse housing and is recessed from its side surface to limit background illumination angles. Housing of the optical target sensor has a cylindrical shape. In the housing of the optical target sensor there is a printed-circuit board of the electronic unit with photodiodes and a printed-circuit board of the electronic unit with pulsed laser diodes. Photodiodes are installed in slots on the end face of the printed circuit board so that the angle between the optical axis of the photodiode and the longitudinal axis of the fuse of projectile is 90°. Power supply is installed in fuse housing nose under conical fairing.

EFFECT: providing target detection at high values of projectile miss on the target.
