Laser-Raman Measurements in the Muzzle Blast Region of a 20-mm Cannon

Abstract

Laser-Raman diagnostics have been used to determine the temporal variation of N2 and CO number densities in the muzzle blast region of a 20-mm Vulcan cannon. The measurements were made within 3.18 to 13.0 mm of the muzzle exit plane on the cannon axial centerline. Propellant WC-870 was used, and the rounds were downloaded to give a muzzle exit velocity of approximately 470 m/ sec. A standard 98-gram projectile was launched.
