The research explored engineering methods for specific heat flow calculation in laminar

boundary layer on non-permeable “wall” of hemisphere surface in a supersonic gas

flow. In this paper we present the results of examining these methods and estimating their

accuracy. The study delves into the ways of solving the problem, proposed by I.N. Murzi-

nov and offers a similar engineering technique of high accuracy in accordance with

modern scientific and technological achievements. Consequently, we to large extent ex-

panded the variation range of such determining factors as Mach number in the incoming

air stream, the brake pressure of this flow, enthalpy.

Keywords

: specific heat flow, supersonic gas flow, laminar boundary layer, engineering

methods.
