High velocity load in AEDC facility Published Dec. 22, 2008 By 208149 Arnold Air Force Base, Tenn. -- David Brown and Troy Perry, Aerospace Testing Alliance outside machinists, install a slug projectile with a pitch motor installed into the 8-inch bore diameter barrel of Arnold Engineering Development Center'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 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) -AEDC-
