ABSTRACT:
A variable camber vane comprises a plurality of articulated spanwise segments which can be operated by a mechanism of pivoted links at one end. A plurality of such vanes may be arranged in a supporting frame to act a variable thrust deflector for the exhaust of a lift engine. In a VTOL or STOVL aircraft installation the vane array is mounted on the underside of the aircraft below a downwardly exhausting lift fan and the range of movement of the variable vane array is used to vector lift thrust between a mainly downward direction and a direction having a substantially rearward component.
