A next step in aviation will include a step in power train hybridization to target a reduction in emissions and to limit the environmental impact of air travel. One of the concepts with potential of increasing aero-propulsive efficiency is the distributed Over-The-Wing (OTW) propulsive concept. To obtain a further understanding of the performance of this concept, a numerical aero-propulsive performance investigation into the wing shape and propeller position of an over-the-wing distributed-propulsion configuration is made. Results show the ability to increase the propulsive efficiency of the system by altering the inflow angle and axial flow velocity to the propeller. Altering the wing geometry below the propeller showed potential in augmenting the beneficial propeller-wing interaction. The research shows that there is a strong sensitivity in changing the propeller axial position, propeller incidence, shroud incidence and wing shape in an OTW configuration.
