Consideration of Influence of Viscosity Effects on Flow and Aerodynamic Characteristics of Combined Rocket Fairings

At present in experimental aerodynamics the convergence of results of experimental determination of aerodynamic coefficients for models of rockets whose bodies are made in a form of a rotation body as various combinations of conic bodies (e. g. with a blunt conic nose part, central cylindrical or quasi conic section and conic tail stabilizer) is an urgent problem. The experiments were conducted in wind tunnels with various degree of the flow turbulence. This problem becomes especially important when experimental results obtained in wind tunnel are compared with those in a free flight because the turbulence degree in the atmosphere is substantially less than that of wind tunnel.
