Numerical study of mass addition influence on heat transfer of two models of descent space vehicle at hypersonic flow regimes is carried out. Numerical simulation is fulfilled using Navier-Stokes equations in axisymmetric statement. The first model geometry and flow conditions are correspond to those in experimental work [1], and the second model corresponds to descent space vehicle of ExoMars project. Various mass flow rates are considered in order to investigate effect of gas injection on values of heat flux. Calculations are carried out using in-house software package HSFlow. Comparison of the results with experimental results [1] and numerical results of other authors is made.
