Abstract
A series of free-flight tests were conducted at an open range to study the flight characteristics and operation of several internal components of a generic reaction jet controlled projectile. This series of tests is the preliminary phase to the firing of the completely operational research projectile. A total of 7 cone-cylinder-flare projectiles, presenting different internal configurations, were fired during this experiment. The first three were fired without any of the internal components to specifically study the aerodynamic characteristics of the projectile, such as stability, spin rage and drag. The following two were fired with the electronic module and the squib installed in their respective internal cavity position, to analyze the operation of the ignition system. Finally, the last two were fired with the rocket motor, but without any connections to an ignition system, to study the effects of acceleration on the propellant. A newly designed sabot was used to fire the projectile at Mach 2.3 from a 110 mm smooth bore gun. The design, fabrication, and integration process of the four components (model, squib, motor, and electronic module) of this project are reviewed and discussed. The results acquired during the trials led to the determination of the aerodynamic properties of the projectile. TRUNCATED
