METHOD OF CONTROL OF MANNED SPACECRAFT UNMATED FROM NON-ORIENTED SPACE OBJECT FLYING IN NEAR- CIRCULAR ORBIT

摘要

FIELD: space engineering; emergency escape from space object. SUBSTANCE: method includes generation of withdrawal pulse after separation from space object, orientation of manned spacecraft for coincidence of its longitudinal axis with orbital velocity vector and furnishing correcting pulse. Space object is additionally detected through visual observation devices. Field of view of observation devices in plane passing through longitudinal axis of manned spacecraft is no less than 90 deg. and one of its boundaries coincides with its longitudinal axis; and no less than 5 deg. in perpendicular plane. In case space object is not observed, manned spacecraft is twisted around its longitudinal axis till space object has been observed; then, correcting signal is furnished to ensure safe autonomous flight of space object and manned spacecraft after unmating of manned spacecraft during several turns , as well as during furnishing deceleration pulse before landing on earth. Direction of furnishing correcting pulse is determined by magnitude of sighting angle on space object relative to direction of orbital velocity vector. If this angle is lesser than 90 deg. , correcting pulse is furnished opposite direction of orbital velocity vector and if this angle exceeds 90 deg. , correcting pulse is furnished in direction of orbital velocity vector. EFFECT: self-sufficiency and safe withdrawal of manned spacecraft from space object. 6 dwg
