Two-Stage Light-Gas Gun Installation for Hypervelocity Impact Studies

Abstract

The report describes a constant base pressure two-stage light-gas gun system installed at North Carolina State University at Raleigh for studying hypervelocity impact phenomena. The gun uses helium gas as propellant and can produce velocities up to 20,000 feet per second. A description of the problems encountered in developing the experimental facility and solutions developed to meet these problems are presented. The components which were designed by the authors include target support, breech support, gas deflector, impact chamber extension, piston and projectile. These components are unique to this installation and have facilitated target alignment, optical measurements and firing the gun.
