| Shrnutí: | Title screen The work proposes the method to design high-rate axisymmetric air intakes through the flow reverse in a respective isoentropic nozzle. Calculation of the flow configuration and parameters in the isoentropic nozzle with the straight characteristic and preset exit Mach number is carried out by the method of characteristics. Then it is suggested that as the flow direction is reversed in the built nozzle contour, flow parameters do not change, but a compression flow appears which corresponds to the flow in the air intake. For comparison, the numerical simulation of the flow in the reversed air intake was made for the enter Mach number M = 6 and in the similar air Busemann intake. The calculations of the non-viscous flow, the total pressure recovery factor in the reversed air intake is 0.996, whereas in the air Busemann intake it is 0.985. The calculations involving the viscosity show that the presence of the boundary layer causes higher losses and reduction of the recovery factor to 0.869 in the the reversed air intake and to 0.832 for the Busemann air intake.
