Vogel, R J; Wahl, R L

A gas dynamic laser device is formed having an elongated linear combustor having a trapezoidal cross-section. The combustion chamber is formed having a short front plate with two side plates extending rearwardly at an angle to an open end. A short flange extends outwardly from the free end of each side plate and an elongated plate extends forwardly from each short flange to a point located in front of each short plate. A plurality of ribs are placed along the length of said elongated linear combustor normal to the side plates. A primary injection device is placed in said short front plate between each adjacent pair of ribs and a secondary injection device is placed between each adjacent pair of ribs, alternating between side plates extending for the length of said combustor. The oxidizer is passed through the nozzle plates of the nozzle assembly for cooling it and passed through passages in the side plates of the combustion chamber for cooling them. The oxidizer is then passed to the primary injection device for mixing with fuel to be injected therein with a portion of the oxidizer being passed on to a secondary injection device for injection upstream toward said primary injection device.
