Abstract:

Based on specific operational constraints, a variety of nozzle design concepts for a deuterium fluoride chemical transfer laser were examined. A family of two-dimensional nozzles expanding in a plane perpendicular to the optical axis were identified to possess a variety of potential advantages particularly in reduction of shock interaction between nozzles and in alleviating fabrication problems. The liability associated with this reverse expansion concept is an inherent increase in nozzle length. Extensive analysis and nonreacting aerodynamic tests indicated that reverse expansion nozzles did maintain reasonable flow character despite the greater length. A complete nozzle array employing this concept has been fabricated for application to the Army DF-C02 transfer chemical laser to determine the optical power extraction behavior of the concept.
