ABSTRACT:
A variable area nozzle 20 comprising spaced fixed inner and outer walls (21,22 respectively) downstream of which is provided a pivotal visor 24, a translatable shroud 31 and an intermediate wall 27 which extends at least partly across the gap between the visor 24 and shroud 31. The leading edge of the wall 27 is constrained by trackways 28 move along a path adjacent the arc of movement of the visor and the wall 27 is constrained either by the pressure in the nozzle or by means on the shroud 31 to contact the shroud 31 at a downstream region of the wall 27. The visor 24 is rotated about its pivot to vary the cross-sectional area of the nozzle and the geometry of the nozzle is defined by the relative positions of the visor 24 and wall 27. The attitude of the wall 27 is varied by moving the shroud 31 and by moving the leading edge of the wall 27 along the trackways 28.
