The wind tunnel is still an important pillar for the aerodynamic investigations of engine installation effects, such as the strong aerodynamic interferences between an underwing mounted engine and the wing itself. To consider real engine effects on t

In a joint effort ONERA and DLR have assessed the interference effects of a generic twin-engine transport aircraft configuration equipped with throughflow nacelles. Both experimental and theoretical investigations were performed. The results showed t

The drag determination of powered configurations equipped with Turbine-PoweredSimulators (TPS) at transonic speeds in the wind tunnel is basically the problem of correct net thrust determination, since neither drag nor thrust can be measured directly
