A simultaneous calculation was made of the processes in the nozzle array and in the resonator cavity of a supersonic cw chemical HF laser. A numerical investigation and of the characteristics of a laser with a three-jet nozzle array and the nozzle-nozzle-nozzle configuration was carried out within the framework of the full system of the Navier-Stokes equations. This investigation yielded dependences of the specific output energy and of the lasing zone length on the coefficient of secondary dilution of the active medium with helium for different coefficients representing the excess of the secondary fuel.
