Heat transfer in the region of the leading edge of a hypersonic 
flying vehicle has been calculated by finite-difference integration 
of the Reynolds equations closed by the low-Reynolds version of the 
k- model of turbulence. Integration has 
been performed using the explicit-implicit McCormack scheme. It 
is shown that blowing of a cooling agent through a porous insert can 
lead to a substantial decrease of heat flux. The Darcy equation was 
used in solution of the conjugate problem.
