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)
