COMPARATIVE ESTIMATION OF EFFICIENCY TWO MANEUVERS CLEARING OF EARTH SPACE BY THE SPACE TRAWLER AT DIFFERENT WAYS OF ITS INJECTION ON DEMANDED ORBIT

N.M. Dron, P.G. Horolsky, L.G. Dubovik

The way of clearing earth space from space debris by a space trawler (SТ), carrying out one of two maneuvers is considered: disposable transition from a high orbit on low or cyclic movement between high and low orbits. Depending on type of applied propulsion systems for injection and descent of КТ the comparative estimation of efficiency of these maneuvers is given at use for injection of trawlers into demanded orbits of launch vehicles of various load-carrying capacity. As criterion of estimation the area of a collecting surface of a passive catching element and total operating time SТ at a stage of clearing are considered.

Key words: earth space, space debris, a space trawler, maneuver, a passive catching element, a launch vehicle, propulsion system.
