This work focuses on over-the-wing engine integration for Flying V Aircraft, an underexplored area with the potential to reduce fuel consumption by 20% through reduced cruise drag. This research experimentally investigates the aerodynamic impact of an over-the-wing engine installation using a 4.6% scaled down Flying V wind tunnel model tested in the Open Jet Facility at TU Delft. Aerodynamic forces and inlet performance are investigated for mass flow ratios of 0.3, 0.7, and 2.1, representing windmilling, cruise, and takeoff conditions for various angles of attack. The results provide insights into the aerodynamic behavior, and inlet efficiency, which is essential for achieving decreased fuel consumption. rnrnThis research is also relevant to other aerospace applications involving integrated propulsion systems, including blended-wing body (BWB) aircraft, UAVs, and future hybrid-electric aircraft concepts. By enabling more aerodynamically efficient aircraft designs, this work supports reductions in fuel burn, and emissions, contributing to sustainable aviation and broader societal climate goals.
