Abstract
A study was performed of methods for
controlling thermal regimes in a spatial
supersonic flow around a blunt body with
the simultaneous use of gas injection
from the surface of the porous bluntness
and heat flow in the shell material. The
effect of the nonisothermicity of the
shell wall on the heat-and mass-transfer
characteristics in the boundary layer
was taken into account by solution of
the problem in a conjugate formulation.
It is shown that heat conducting
materials can be used to advantage to
reduce the maximum temperatures in the
screen zone. P. 114-119
