Propulsion and launching analysis of variable-mass rockets by analytical methods
Propulsion and Power Research, 2013 In this study, applications of some analytical methods on nonlinear equation of the launching of a rocket with variable mass are investigated. Differential transformation method (DTM), homotopy perturbation method (HPM) and least square method (LSM) were

Attitude stability and altitude control of a variable-geometry Earth-orbiting solar sail [PDF]
, 2016 A variable-geometry solar sail for on-orbit altitude control is investigated. It is shown that, by adjusting the effective area of the sail at favorable times, it is possible to influence the length of the semi-major axis over an extended period of time.

Equations of motion for the variable mass flow-variable exhaust velocity rocket [PDF]
Astrodynamics Conference, 1972 An equation of motion for a one dimensional rocket is derived as a function of the mass flow rate into the acceleration chamber and the velocity distribution along the chamber, thereby including the transient flow changes in the chamber. The derivation of the mass density requires the introduction of the special time coordinate.

General motion of a variable-mass flexible rocket with internal flow [PDF]
Journal of Spacecraft and Rockets, 1970 This paper consists of two parts. In the first part a new and general formulation of the dynamical problems associated with the powered flight of variable-mass , flexible rockets with internal gas flow is presented. The formulation comprises six ordinary differential equations for the rigid-body motion and three partial differential equations for the ...

Robust multi-fidelity design of a micro re-entry unmanned space vehicle [PDF]
, 2011 This article addresses the preliminary robust design of a small-scale re-entry unmanned space vehicle by means of a hybrid optimization technique. The approach, developed in this article, closely couples an evolutionary multi-objective algorithm with a ...
