Afanasyev V.A., Mayshev A.E., Anisimov K.Yu. Elaboration of mathematical model of flight trajectory of material point in atmosphere

Research Article. — Vibroengineering Procedia. — September 2018, Volume 19. — P. 246-252.In the article, the flight trajectory of a material point in the atmosphere is considered. For its calculation the Runge-Kutta method and the system of the equations of external ballistics are used. Moreover, the approximation of the resistance function according to the 1943-year law for subsonic and supersonic speeds is made. The expansion of dependences of the excess above the line of aiming and flight time from the distance in Taylor’s series is implemented. The results of researches are used in solving the direct problem of external ballistics for the definition of trajectory parameters with an increased accuracy.System model.
