Title: Innovations by Inventor Sung K Chung

Introduction

Sung K Chung is a notable inventor based in Dover, PA (US), recognized for his contributions to the field of small caliber munitions. With a total of 4 patents to his name, Chung has made significant advancements in projectile technology, particularly for military applications.

Latest Patents

Chung's latest patents include the "Dynamic instability reduced range round," which describes a multi-piece projectile designed for small arm training ammunition. This innovative round maintains stable flight until it reaches transonic speeds. During transonic and subsonic flight, aerodynamic features on the projectile create a pressure differential that enhances limit cycle motion. These features are strategically placed to avoid interaction with the rifling elements of the gun barrel, potentially including protrusions or extrusions from the projectile.

Another significant patent is the "Long rod penetrator concept for small caliber munitions." This invention presents a kinetic energy penetrator that can utilize composite material small sabots. The design incorporates a large shear area in the sabot with a limited number of decreasingly sized buttress grooves, which effectively mates with the penetrator shaft. By lightening the penetrator through the use of composite material sabots, Chung's design achieves greater velocity and higher kinetic energy upon impact, while the fewer grooves reduce aerodynamic drag.

Career Highlights
