Determination of Necessary Commands for the Motion of a Rocket on a Given Linear Trajectory in the Atmosphere,

Abstract

The variation in time of the attack angle of the control surfaces of a rocket so that it is moving on a given linear trajectory in the atmosphere is determined in this paper. Variation of aerodynamic coefficients with the Mach number is considered as well as the variation in time (in the fuel combustion stage) of the moments of inertia and the position of the center of mass of the rocket. Air density and sound velocity are assumed variable with the altitude. A numerical calculation example solved with the algorithm presented in this paper is shown in the end. (Author)
