Abstract: A cascade thrust reverser for a fan-jet engine comprising a two portion shroud surrounding the engine forming a duct therebetween for the rearward directional flow of bypass gases. The forward portion of the shroud is fixed in position. The rear portion of the cowl translatable from a forward reverser stowed position to a rear reverser deployed position. An opening is provided between the two cowl sections for bypass gases to exit the duct when the reverser is deployed. A plurality of pairs of cascade baskets are positioned around the circumference of the cowl intermediate the shroud walls; one of each pair is positioned over the other and nest in a cavity in the forward wall of the rear shroud portion when the reverser is stowed. The innermost cascade baskets pivot into the duct when the reverser is deployed, and direct the bypass gases through the outer cascade baskets for reversing the direction of the flow of bypass gases.
