COMPUTING EXPERIMENT BY DEFINITION OF AERODYNAMIC CHARACTERISTICS OF A CYLINDRICAL BEAM WITH A STRAKE

Abstract

On the basis of methods of computing aerodynamics (CFD) research by definition of aerodynamic effects from the strake on a tail boom of cylindrical section is conducted and the estimation of the constants and variable forces operational depending on the strake angular rule.
