High-Capacity Artillery Projectile (HICAP) Fin Characteristics

Abstract

One of the key technologies being developed for the High-Capacity Artillery Projectile (HICAP) is an out of bore deployable fin assembly. The fin assembly must stabilize the projectile and maintain the reduced spin level imparted by the slip obturator. The design described herein uses a rearward opening, foldout fin. This fin has acceptable aerodynamic characteristics and deploys utilizing the projectile spin imparted from the obturator. The fin blades are concealed during launch in a base module that is easily obturated. This report contains design factors, predicted aerodynantics, and results from the fin opening tests.
