Wpływ spadochronu na ruch zasobnika osiowo symetrycznego zrzucanego z samolotu

The paper presents an analysis of dynamic properties of a freely moving object equipped with a braking parachute and an accelerating rocket engine. The object is treated as a rigid body with five degrees of freedom. The movement of the object is described by a system of second-order non-linear differential equations. The equations were integrated numerically for the assumed initial conditions. Flight paths, variations of angles of elevation asimuth attack and sideslip, variations of velocity of the centre of mass and its components were calculated for different airdrop parameters. Aerodynamic characteristics were obtained empirically from model testing in a wind tunnel.
