ADVANCED MIXING NOZZLE CONCEPTS FOR COIL

摘要

This paper investigates advanced mixing nozzle concepts for the chemical oxygen-iodine laser (COIL) that will significantly improve the chemical efficiency of such systems. It is believed that innovative nozzle design improvements should increase COIL chemical efficiencies. This technology will logically include injection of atomic rather than molecular iodine. The resulting family of advanced nozzles will have major implications for the military programs as well as evolving industrial COIL systems. Research into these concepts will improve chemical efficiencies, reduce gain generator subsystem cost and weight, reduce loading on optical components, and improve pressure recovery. Use of the well calibrated and economical VertiCOIL facility at UIUC will allow a number of advanced nozzle concepts to be implemented and examined in detail.
