30 MM, XM552, Spin Rate Measurement Utilizing Spinsonde.

Abstract

Spin rate is a critical parameter in designing shape charges and self destruct fuzes. An accurate determination of spin rate history over the entire free flight trajectory of the projectile is, therefore, important. Harry Diamond Laboratory developed an instrument, called Spinsonde, for the determination of spin rate of automatic cannon caliber projectiles. The 30-mm XM552 cartridge, with the 30 mm XM553 high explosive dual purpose (HEDP) projectile, was the test vehicle for this investigation. The Spinsonde system consists of an oscillator and a power supply which is installed in the nose of the projectile. The telemetry package transmits a signal in free flight which is received on a station downrange. This report describes the method used to measure the spin rate and presents a comparison between the theoretical and experimental results.
