    Abstract: A gas turbine engine recuperator including exhaust passages providing fluid flow communication between an exhaust inlet and an exhaust outlet, the exhaust inlet being oriented to receive exhaust flow from a turbine of the engine and the exhaust outlet being oriented to deliver the exhaust flow to atmosphere, the exhaust inlet having a smaller cross-sectional area than that of the exhaust outlet, and a cross sectional area of each exhaust passage progressively increasing from the exhaust inlet to the exhaust outlet such as to diffuse the exhaust flow. Air passages are in heat exchange relationship with the exhaust passages and provide fluid flow communication between an air inlet and an air outlet designed to sealingly engage respective plenums of the gas turbine engine.

    Abstract translation: 一种燃气涡轮发动机换热器，包括排气通道，其提供排气入口和排气出口之间的流体流动连通，所述排气入口被定向为接收来自所述发动机的涡轮机的排气流，所述排气出口被定向成将排气流输送到大气， 排气入口具有比排气出口小的横截面面积，并且每个排气通道的横截面面积从排气入口逐渐增加到排气出口，从而扩散排气流。 空气通道与排气通道处于热交换关系，并且在空气入口和设计成密封地接合燃气涡轮发动机的各个通风室的空气出口之间提供流体流动连通。

    Abstract: A vane assembly of a gas turbine engine includes a plurality of circumferentially spaced vanes extending radially between an outer case and an inner case. A spring-tensioned stator restraining strap is provided around the outer case and surrounding outer ends of the respective vanes. The outer ends of the vanes are received in corresponding openings defined in the outer case and project radially outwardly from the outer case. The spring-tensioned strap compresses the respective vanes radially and inwardly in position.
