Model aerodynamiczny i opis matematyczny ruchu wydłużonego pocisku ciężkiego

A physical model and mathematical description of whirling elongated flying object with a high relative elongation and a high cross-section load, moving with supersonic velocity has been formulated. A mathematical model of the spatial motion in athmosphere of this, in many respects specific, object – (elongated sabot armour-pierced shell), has been derived. As a result of suitable choice of the reference system we were able to reduce the degree of non-linearity. The applications of the mathematical model of the motion enable us to obtain the direct information on the main features of the trajectory and its characteristics.
