FIELD: transport.
SUBSTANCE: invention relates to means of satellite aerodynamic braking used to deorbit satellites after expiration of their life. Aerodynamic surface 2, 3 of satellite 1 serves to increase satellite drag without special stabilisation in orbit. Proposed surface comprises one or several elements that, when unfolded, make 3D structure made up of at least two panels 2a, 2b, 3a, 3b that form a dihedron. Each pair of panels unfolds from one mast of unfolding arranged along edge 6, 7 of appropriate dihedron. Panels 2, 3 are made up of flat flexible membranes tightened on both sides of retaining elements perpendicular to said mast.
EFFECT: lower weight and power consumption, higher reliability.
