Abstract
The paper presents analytical dependencies making it possible to determine the laminar relative heat flow supplied to the surface of a blunt rotation body flown around by the supersonic gas flow. Since solving the corresponding Navier --- Stokes or boundary layer equations requires serious time effort, obtaining such dependencies becomes an important tool in preliminary estimation of the heat flow significant parameters. The currently existing approximate formulas were obtained primarily for the spherical bluntness. In the case of studying the gas flow around ellipsoids, paraboloids and other convex surfaces, the local spheres rule is applied, when the heat flow on the body is accepted to be the same as on the sphere with the angles of the flow meeting the body surface and the sphere under consideration coincide. This approach often produces an error unacceptable in the engineering calculations. This is because formulas for the sphere were obtained based on a large number of simplifications. The obtained dependence is not limited to the spherical noses and was obtained for the case of a cold wall and large values of the Reynolds number. By comparing with the numerical solutions, the paper shows that the obtained dependence perfectly describes relative heat flow to the wall. The data obtained makes it possible to assess the heat flow values that are critical for a product at the early design stages
