With use of the method of linear stimulate the purpose integration of system differential equations moving of centre inertia of ballistic body is proposed. Force of head-resistance of air, being of which in equalizations of motion, changes them on substantially nonlinear, it is presented as quadratic trinomial in relation to a dimensionless parameter are numbers of Stroke, with unknown coefficients. In the linear approaching expressions are got component of vector of rate of movement for a trajectory in atmospheric terms (real trajectory), and also the method of calculation of variations of distance and complete block hours is indicated. The method of finding of aerodynamic coefficients is developed by information, kinematics descriptions of free flight got by measuring.
