Radio Frequency Oscillator Technique for Monitoring Velocity and Structural Integrity of Projectiles during Their Exit from the Muzzle
Abstract
Accurate knowledge of projectile velocity and integrity at muzzle exit is requisite to many aspects of research, development, product assurance, quality control, and field employment of projectile-gun systems. Standard methods for obtaining such information have severe limitations of applicability. As a result of a recent thrust program in the technology area of projectile-gun dynamics, a radio frequency oscillator technique has been developed and successfully tested for the 105mm M68 tank gun system. It provides real time measurement of projectile exit from the muzzle and, hence, projectile muzzle velocity. The electronic pulse associated with the measurement can also be used to trigger auxiliary instrumentation such as x-ray pulses and photographic cameras and to automatically adjust the corresponding delay times to the correct projectile muzzle velocity.
