Abstract
A device for coupling a flexible envelope (1) to an external element including a ballonet (3) with two fasteners (4, 5) located in such a manner as to define the upper and lower poles of said ballonet, one of the fasteners (5) being linked by coupling members (2, 16) fitted to position the ballonet with respect to the envelope (1) in such a manner as to create a contact surface Z1 between said ballonet and the envelope (1), the second fastener (4) being linked to the external element by link means (8-15) including drive means to set the ballonet (3) in rotation; this device makes it possible to transmit large point forces or torques between an external element and an envelope, especially a space-balloon envelope.
