SYSTEM FOR MEASURING THE YAW, SPIN AND MUZZLE VELOCITY OF AN AMMUNITION PROJECTILE

摘要

An ammunition projectile has a plurality of distinctive marks arranged in at least one circular row around the projectile body, with the row of marks extending perpendicular to its longitudinal axis. The marks are illuminated by a strobe flash and successive images are captured by an electronic imager as the projectile exits the barrel of a weapon. A computer, coupled to the imager, processes the electron is signals to determine projectile yaw, spin and muzzle velocity.

1. A projectile configured to be fired from a gun barrel of a weapon, said projectile having a cylindrical body defining a central longitudinal axis, the improvement comprising a plurality of marks on said projectile arranged in at least one circular row around said body, with said row extending perpendicular to said longitudinal axis, said marks being of such character as to be seen by an optical detector while exiting from the barrel.
