Аннотация:The aim of this work is the development of computational tools based on the solution of the system of Navier–Stokes equations for numerical study of viscous gas flows in the nozzles of liquid propellant rocket engines with a thrust optimized contour of the supersonic part with separation of the laminar boundary layer from the wall. The energy and thrust characteristics of these engines are determined for the flow with separation in the nozzle for a wide range of nozzle pressure ratio. https://doi.org/10.3103/S1068799822040213
