Abstract
A vectorable nozzle for a vertical lift aircraft comprising an array of lift flow deflecting vanes mounted in a frame hinged to an undersurface of the aircraft. The nozzle is formed by a plurality of telescopic shroud members which together with the vane frame are mounted at their forwardmost ends. The disposition of the vanes is such that the lift flow is directed downwards when the nozzle is extended. When the nozzle is retracted the flow is vectored rearwards to provide forward thrust. In this position the nozzle generates minimum aerodynamic drag from forward movement of the aircraft. The nozzle preferably is fully stowed within the aircraft, and concealed by surface doors when not in use.
