Rockets 4a, 4b are then free to move about their pivotal axes and steer the structure. The opposed rockets 4a are pivoted on brackets 14 to swing about axes arranged transversely to the longitudinal axis 20 of the structure, when fluid pressure motors are actuated. The motors, which are pivoted on a column 24, comprise cylinders 22 in which slide piston rods 26 pivoted on the rockets 4a. The second pair of rockets 4b, are mounted for universal adjustment in gimbals 16, the gimbal rings 30 being adjustable by fluid pressure mechanism 34, 36 also pivoted on the column 24 and the rockets 4b are adjusted within the rings 30 by fluid pressure devices 38. |
