NONEQUILIBRIUM MOLECULAR RADIATION NEAR A SPACE VEHICLE AT THE MARTIAN ATMOSPHERE ENTRY

摘要

The results of developing a model of nonequilibrium radiation of molecular components CO, CN, C_2, NO in the shock layer during the flight in the Martian atmosphere are presented. To verify the model, some experimental investigations are carried out in the arc-driven shock tube. Relying on the developed kinetic and numerical model based on the 2-D full Navier-Stokes equations, the radiative heat fluxes are estimated at the stagnation point of the Mars Probe space vehicle and of the segmentally-conical space vehicle. The radiative heat fluxes in the base region of the segmentally-conical vehicle are also calculated for the trajectory point V=6 km/s, H=60 km.
