FIELD: laser engineering; experimental debugging of pressure recovery systems. SUBSTANCE: gas-dynamic simulator of supersonic HF (DF) chemical laser has gas generator with injector head, fire-bottom head, fuel and oxidizing agent supply pipe, combustion chamber, and supersonic nozzle. Gas-dynamic simulator is provided with dynamic mixer of oxidizing media. Combustion chamber has external hollow annular manifold for feeding diluting gas with spray injectors uniformly arranged over ring. Provision is made for feeding diluting gas to combustion chamber in opposite direction to flow. EFFECT: enhanced effectiveness of chemical laser simulator. 5 dwg
