The drogue 11 comprises a canopy 50 supported by a plurality of adjustable ribs 42 and further ribs 43. A control unit 36 is provided for moving the adjustable ribs 42 into a first position P1, in which an air stream can inflate the canopy 50 whereby drag on the canopy causes the drogue 11 to draw a fuel hose 74 from a tanker aircraft 63 into an extended position, and into a second position P2 in which the canopy 50 takes on a cylindrical form and drag thereon in the extended position will be reduced. Selected adjustable supports are movable relative to the others by a control mechanism 41 to adjust a selected portion of the canopy 50 whereby the drag on that portion will be increased and the drogue 11 will move to a new position. |
