Abstract
A hypersonic wedge nozzle for chemical lasers that has a radially diverging low primary nozzle with a multiplicity of hypersonic wedge type secondary injection wedges at the exit end of the primary nozzle to allow gas flow to become supersonic in the primary nozzle before entering the regions between the secondary injection wedges or the surfaces thereof. Utilization of the large diverging primary nozzle in producing supersonic flow minimizes viscous effects in producing the supersonic flow in a chemical HF or DF laser.
