This paper presents a detailed study of a flapped outflow valve. Well-known as part of the pressurization system of aircraft, this type of valve is also designed for thrust recovery even if the efficiency of the system has never been demonstrated. Aground experimental test rig is first designed to provide global and local measurements to be used as validation data for numerical simulations. Once the validation of the numerical approach is achieved on a ground configuration, additional three-dimensional computations are then conducted for cruise conditions. They lead to a reliable estimation of thrust recovery as well as interesting insight in the aerodynamic behavior of the flow across the valve and its associated three-dimensional effects
