Possible methods are considered and a computational experiment technique for calculating the aerodynamic characteristics of feathered aerodynamic objects is proposed. Its verification was carried out on an object of simple shape (cone + cylinder) with subsequent matching of the obtained values for the object under study with the available experimental data. The shape coefficients and drag coefficients are calculated depending on the Mach number for an aerodynamic object with two forms of the head by the method of a computational experiment. Ballistic coefficients are obtained according to the laws of 1943 and 1958, as well as according to the Siacci law as functions of the Mach number. The obtained drag coefficients will be used for calculation of the initial data for launching the aerodynamic object.
Keywords: aerodynamic object, body flow simulation
