On the Dynamics of Variable Mass Systems

Abstract: This report presents the results of an investigation of the effects of mass loss on the attitude behavior of spinning bodies in flight. The principal goal is to determine whether there arc circumstances under which the motion of variable mass systems can become unstable in the sense that their transverse angular velocities become unbounded.Obviously, results from a study if this kind would find immediate application in the aerospace field. "The first part of this study feann_s a complete and mathematically rig… Show more

“…Z kolei w systemach, w których zachodzi znaczna wymiana masy, zwłaszcza w krótkim czasie, należy uwzględnić ten proces w badaniu dynamiki -w przeciwnym razie wszelkie przewidywane odpowiedzi układu będą dalekie od jego rzeczywistego zachowania [3].…”

“…While rocket dynamics comprises a vast, long-studied area of research (Meirovitch 1970;Brusch 1977;Ge & Cheng 1982;Calise et al 1998;Banerjee 2000;Eke & Mao 2000;Dukeman 2002), prior to the recent work of Srivastava et al (2010) and Keanini et al (2011), the significant question concerning rocket response to random, in-nozzle side loads remained open.…”

“…Based on Kane's formalism and volume integrals, 6 under the assumption of axi-symmetric and/or negligible displacements of matter inside the rocket, the dynamics of a variable mass rigid body is given by the following equations, where V is the speed relative to an inertial frame of a fixed point of the rocket and CG is the vector distance of this point with respect to the center of gravity…”
