Propeller-wing interaction has been a topic of investigation since the dawn of aviation. Surprisingly, however, there are few published studies showing how changing a tractor propeller’s vertical offset affects a trailing wing’s lift and drag distributions. In this work, we investigate this for a rectangular wing with an inboard propeller using steady Reynolds-averaged Navier–Stokes computational fluid dynamics and an actuator-disk approach. We present results for two angles of attack and a range of propeller-wing vertical offsets for both inboard-up and outboard-up propeller rotation. We include plots for spanwise sectional lift and drag coefficient distributions, integrated lift and drag coefficients, lift-to-drag ratios, and chordwise sectional pressure-coefficient distributions. The results show that changing the propeller-wing vertical offset can significantly change a trailing wing’s lift and drag distributions, which strongly depend on the direction of the vertical offset.
