Investigation of the Performance of Interstage Ducts for Gas Dynamic Lasers.
Abstract
A study was made of the density and velocity distributions in different configurations of a cold flow model of the Airborne Laser Laboratory Interstage Duct. This report includes the results of testing eight different configurations, built on two basic designs. One design had a continuous vortex flow while the other had counter opposing vortex flows being generated at the central cross-section. The parameters in the investigation were the location and size of the purging nozzles, the velocity, and the purge flow rate. The purge flow was air being introduced through nozzles in the perimeter of the interstage duct. The rate at which the radial density gradient increased with increasing flow was almost linear for the continued vortex ducts and asymptotic for the reversed vortex ducts.
