FACILITY FOR LANDING SPACECRAFT Russian patent published in 2006 - IPC B64G1/62 B64D17/34 

FIELD: space engineering; precision and soft landing of artificial satellites in off-standard situations.

SUBSTANCE: proposed landing facility includes parachute system connected with spacecraft by means of lines through control and release unit. Release unit makes it possible to change length of parachute canopy lines and jettison parachute system. Parachute system has four shroud lines connected with spacecraft through line length control unit in points of suspension symmetrical relative to center of mass of spacecraft. Lines are connected with shroud lines by means of four independent connectors with locks opened by command of control and release unit. Line length control unit has four identical channels each including drum, reduction gear and retainer. Retainers are connected with control and release unit by means of said four lines. Length of these lines is changed by signals from control unit in accordance with algorithm ensuring landing of spacecraft at preset point.

EFFECT: extended field of initial conditions of spacecraft descent, especially in off-standard conditions.
