ABSTRACT:
Gas turbine engines, usually of the kind which include ducted fans, have cowl structures which generate drag inter alia by virtue of their frontal area. Where the cowl is of very large diameter i.e. in the order of 3 to 4 meters, if known devices such as thrust reverser cascades are installed in them, the frontal area and weight of the structure would be unacceptable. The invention provides a cowl structure of the magnitude mentioned hereinbefore, in which an improved cascade is installed. The or each cascade comprises a pair of rectangular frames which are joined by vanes. The vanes are pivotably connected to the frames in the manner of parallel rules as used in navigation. When non operative, the frames are stowed in superimposed relationship and thus enable a thinner cowl to be utilized than is possible in known cascade storage arrangements.
