Abstract
Thrust recovery outflow valves for aircraft are disclosed. An example thrust recovery outflow valve includes a flow control member having a first aerodynamic surface and a second aerodynamic surface to define at least a portion of a fluid flow passageway between an inlet and an outlet of the thrust recovery outflow valve. A first portion of the first aerodynamic surface and a first portion of the second aerodynamic surface provides a converging profile between the inlet and a throat of the fluid flow passageway. A second portion of the first aerodynamic surface and a second portion of the second aerodynamic surface provides a diverging profile between the throat and the outlet of the fluid flow passageway. The fluid flow passageway is positioned at a small angle relative to an outer surface of an aircraft to enable fluid exiting the fluid flow passageway to provide a thrust recovery vector oriented substantially parallel to the outer surface of the aircraft and opposite a direction of drag.
