- This article, published in the top-ranked nonlinear sciences journal, presents the first non-numerical technique to evaluate the pointing stability of rocket motors. This is achieved using the only known analytical solution to nutation angles for mass-varying systems, separately derived by this UoA’s author. The main contributions here are: a mathematically rigorous analysis of solid rocket motors’ flight dynamics under a spectrum of mass variation assumptions; and corrections to previous findings on unstable flight dynamics of oblate upper stage rockets. The paper was central to collaborations with NASA-JPL (Saptarshi.Bandyopadhyay@jpl.nasa.gov) and securing a permanent contract at QMUL.
