An aircraft includes a body 10, at least one nozzle 16 mounted for movement between an aft-directed position and a downwardly directed position, the arrangement being such that when the or each nozzle 16 is directed downwardly, the thrust generated thereby is directed along a line which lies substantially on the same lateral plane as an allowable first extremity of the center of gravity of the aircraft (e.g. aftmost). A trim jet 22 is positioned to exhaust beyond a second extremity of the center of gravity (e.g. foremost) and arranged to generate a trim thrust component to compensate for movement of the center of gravity of the aircraft between the first and second allowable extremities. Two nozzles 16 may be provided one to each side of the body 10 thus allowing a yaw component to be generated by differential movement of the nozzles. |
