Abstract
Disclosed is a gas jet device within at least one movable nozzle in rotation, enabling the creation of one or more thrust forces providing for the guidance-control of a carrier. The guidance-control device has a nozzle unit to which a nozzle is fixed. The nozzle, through the movable nozzle unit, is put into rotation by a rotation-driving device which may be, for example, a rotation-driving device. This pneumatic control device has a control piston provided with a rack device and cylindrical chambers. Through a gas distribution system, these cylindrical chambers undergo pressure variations which give the piston a translational motion. This piston transmits a rotational motion, through a toothed wheel, to the nozzle unit and, hence, to the nozzle. With a gas generator feeding the nozzle or nozzles, and with the guidance-control mode being chosen, all that remains is to position the nozzle or nozzles according to the desired aperture angle to obtain the desired direction.
