Abstract

Aviation is responsible for a large part of the emissions due to transportation, which is why, in recent years, a trend towards implementing sustainability in aviation has emerged. In small aircraft, the concept of Leading-Edge Distributed Propulsion (LEDP) can provide aerodynamic advantages to reduce fuel consumption thanks to the ability to increase lift due to the interaction between the slipstream of the propellers and the wing.

Therefore, a wind tunnel experiment is performed to study the aerodynamic interaction in propeller-wing-flap systems when Leading-Edge Distributed Propulsion is used. The objective of this research is to gain insight into the difference in wing loading distribution between the distributed-propeller and single-propeller configurations in the flap retracted case, about the effect of flap position on the lift enhancement in LEDP and about the effect of flap deflection on the wake downstream of the system...
