Abstract
A turbine exhaust system including a bypass fluid duct that includes: an outer exit shroud and an inner mold line (IML) forming a channel from an inlet to an outlet of the bypass fluid duct, a moveable diffuser configured to move between a forward and aft locations, and a door configured to pivot between minimum and maximum door angles, wherein the moveable diffuser and the door together form the outer exit shroud. The bypass fluid duct is configured to: receive an incoming fluid stream in a first direction through the inlet; bypass the incoming fluid stream around a turbine generator; and direct a flow path of the incoming fluid stream from the inlet through the outlet to join an ambient fluid flow. A movement of the door and the diffuser, from an unextended position to a fully or partially extended position varies a shape and volume of the channel.
