Abstract:

A prototype instrument to determine the orientation of a projectile in free flight i.e., roll, pitch and yaw angles was developed at Boeing and used to perform test at the U.S. Army Ballistic Research Laboratory BRL at Aberdeen Proving Ground MD. The instrument incorporated two visible gas lasers to provide a two color collimated illuminating beam and a pair of galavanometer beam deflectors from the detected light reflected of the output beam. All three angles can be determined from the detected light reflected by a retroreflectorhologram combination mounted on the projectile. The prototype instrument was designed to make three-axis angle measurements on in-flight or in-bore spinning or non-spinning projectiles, and to make two-axis angle measurements of gun tube motion. Tests were performed by both Boeing and BRL personnel at the Aerodynamics Range at BRL during a two-week period in August 1985. The test instrumentation was then left at BRL for additional testing by BRL personnel.
