Abstract
The present invention discloses a device for varying the fluid passage area between adjacent turbine stator vanes. Upstream and downstream baffles are pivotally attached to the turbine casing, such that their distal ends may be extended into and retracted from the fluid passage area, so as to vary the cross section of the throat between adjacent vanes. A control system interconnects all of the baffles so as to synchronize and positively control their movements. The invention finds particular use in an aircraft turbojet engine.
