摘要：A lightweight, easily manufactured and assembled thrust reversing cascade assembly for jet engines. The assembly includes a plurality of turning vanes positioned in spaced relation and locatable aft of a jet engine exhaust. Each turning vane is rigidly supported in fixed spacial relation to other such turning vanes by a support assembly which includes a plurality of planar spacer members. Each spacer member includes a tab portion which extends from the spacer body a distance sufficient to pass through a slot in a turning vane. Each spacer also includes a notch on the end opposite the tab to receive the tab projecting through a turning vane from another spacer member. A pair of straps are positioned on both sides of the planar spacer members and also extend through the slots in each turning vane. Tensioning means is provided at opposite ends of the straps to place the straps in tension while providing compression forces on the spacers and turning vanes to rigidly support the turning vanes in spaced relation.
