Paper Abstract

We investigated performance of a gasdynamic laser (GDL) with combustion gas of a double base propellant theoretically. Small signal gain coefficients in the supersonic flow of the combustion gas were calculated for different stagnation conditions characterized as the operation region of conventional GDLs. Preliminary experiments show that less solid particles exist in the combustion gas flow than we expected. It was revealed from theoretical and experimental results that a conventional GDL which uses the doubled base propellant as a gas generator could be realized.
