In-Flight Projectile Imaging by Infrared Emission/Rotating Mirror Technique With Temperature Calibration.

Abstract

Many projectiles experience considerable heating which begins with the launch process in the gun and continues with aerodynamic heating throughout the flight. The high temperatures that result cause the surface to emit considerable infrared radiation. In this work, a rotating mirror system was applied to image projectiles by infrared emission. Factors that affect this system's image quality are identified and described. In addition to imaging, infrared emission may also be used to measure the surface temperatures of projectile components. A technique was developed to calibrate the system for measuring surface temperature. The surface temperature distribution on a tank fired 120-mm M-865 training projectile, with velocity of 1600 m/sec, was measured and is displayed in the report.
