What is it about?
Effects of layout of multiple propellers on aerodynamic characteristics of a fixed-wing are numerically investigated to obtain design guidelines for electric-propeller airplane that typically use multiple propellers. The results show that the wing with one propeller mounted at the wingtip has the highest lift-to-drag ratio at the cruise condition and the lift-to-drag ratio decreases as the number of propellers increased. On the other hand, the results also show the wing with multiple propellers has higher lift coefficient at the take-off/landing condition. We also discuss the physical reasoning by looking at the flow field in detail.

Why is it important?
In electric-propeller airplane design, we have a high degree of freedom in selecting the number of propellers and their layout. This paper clarifies for the first time the effect of multiple propellers on the aerodynamic characteristics of a wing under cruising and take-off/landing conditions and its physical background.
Perspectives
We clarified the effect of multiple propellers on the aerodynamic characteristics of a wing. We expected the knowledge obtained here will contribute to the aerodynamic design of future electric-propeller airplanes.
