DEVICE FOR DETERMINATION OF EXTERIOR BALLISTIC PARAMETERS OF PROJECTILE COMPONENT WITH THE AID OF LIGHT SCREENS Russian patent published in 2006 - IPC F42B35/00 G01P3/68 

FIELD: determination of exterior ballistic parameters (co-ordinates, speed and attitude of projectile components - bullets and projectiles) at a direct laying fire at vertical obstacles (targets).

SUBSTANCE: the device has a light target for determining the speed and co-ordinates of projectile components. Provision is made for measurement of time moments of projectile component entry in the light screens and exit from them, computation of the time moments of intersection of the light screens by the center of the projectile component, the use of these data prevents any error in determination of the speed and co-ordinates due to nutation and precession. The angles of nutation and precession are determined according to the differences of time moments corresponding to the durations of intersection of the light screens with the aid of shadow characteristics predetermined by computation or experimentally.

EFFECT: enhanced precision of determination of the speed, co-ordinates and angles of nutation and precession of the projectile component.
