Title: W Brian Stewart: Innovator in Kinetic Energy Projectiles
Introduction
W Brian Stewart is a notable inventor based in Lancaster, PA, who has made significant contributions to the field of kinetic energy projectiles. With a total of two patents to his name, Stewart's work focuses on enhancing the performance and reliability of military projectiles.
Latest Patents
Stewart's latest patents include the "Pre-molded aft seal for discarding sabot projectiles" and the "Slitted hybrid composite design for gun launch applications." The first patent introduces an armor-piercing fin-stabilized discarding sabot kinetic energy projectile that features a pre-molded plastic aft seal sleeve. This innovative design protects the sabot from damage caused by the propellant and replaces both the RTV and the protective sheath found in conventional designs. The seal is manufactured from thermoplastic polyurethane or thermoplastic polyester elastomer. The second patent describes a rocket motor casing made of helically wound and cured graphite/epoxy resin. This casing includes circumferentially spaced axially extending slits, which are covered by an aramid fiber/rubberized resin system. This design allows the motor casing to withstand inwardly directed circumferential forces during gun launching and outwardly directed forces when the rocket motor is fired.
