AEDC’s Range-G in operation for 50 years

AEROBALLISTIC LAUNCH PREPARATION-Final step is the insertion of powder charge into breech launcher. In sequence, powder compresses hydrogen, hydrogen drives piston, piston compresses hydrogen in pump tube which accelerates model to desired velocity. The free-flight models will be fired through the 1,000-foot range at velocities up to and exceeding Mach 20. The test unit, 1,000-ft Hypervelocity Range-G, is part of the von Karman Gas Dynamics Facility at AEDC. (1963 AEDC Photo)

High velocity load

David Brown and Troy Perry, ATA outside machinists, install a slug projectile with a pitch motor installed into the 8-inch bore diameter barrel of AEDC’s Hypervelocity Range G’s launcher. This projectile will be launched out of the G Range two-stage light gas gun at a velocity of 8,200 feet per second. This is the first test of a new rocket motor that will be used to pitch the Terminal High Altitude Area Defense (THAAD) projectile up to a predetermined angle prior to impacting simulated threat targets. The primary objective of this shot is to verify pitch motor ignition and performance. (Photo by David Housch)
