An aim of research – to establish laws of operation of an active-passive means of de-orbit the space objects (SO) and the extralight launch vehicle (LV) for its ascent which does not litter environment. The basic methods of research are an analytically-calculation and experimental. The basic laws of combined systems operation of de-orbit the bulky SO on the basis of the propulsion system, the aerodynamic sailing device and an autophage LV for their ascent are determined. For the first time it is shown that definition of time of the beginning of de-orbit depending from a solar activity phase leads to economies of mass of propellant components at fixed time of de-orbit and allows to realize the guaranteed de-orbit from low earth orbits (LEO) in dense layers of the Earth atmosphere with the minimum energy expenses. For the first time laws of gasification and body burning of the autophage LV as a propellant component that indicates on capability of working out the solid-propellant engine with a controllable thrust are experimentally established. The received results can be used at planning and implementation of researches concerning a problem of clearing of LEO. An application domain is a space-rocket technique.
