Abstract : Some features of optimal programming of the thrust magnitude and thrust direction structure during the motion of the variable mass point in a central gravitational field are studied. The presented results contain development and generalization of the authors' investigations, reported at the XIVth (1963) and XVth (1964) International Astronautical Congress of IAF. The paper consists of three parts. In the first part the results of the analysis of an optimal disturbed Keplerian two-dimensional motion in the vicinity of the cicular orbit are given on a basis of the p-trajectories theory. The influence of upper atmosphere aerodynamic forces on an optimal correcting program is considered in the second part of this report. In the third part a three-dimensional problem of a satellite elliptic orbit plane turn by a specified angle with a minimal reference velocity is considered. An optimal structure of the modulus and sign control of the jet-force, normal to the orbit plane, is investigated. (Author)
