Energy Optimization of High-Thickness High-Lift Wing for a Blended Wing Drone With Ducted Fan Propulsion and Boundary Layer Ingestion 2018-01-1961
This paper aims to optimize an effective design of a blended wing drone with ducted fan propulsion and boundary layer ingestion. The wing profile has been optimized starting from a well known unified wing profile with high lift and high thickness. Three different wing profiles has been preliminarily evaluated: the classical Glenn Martin 2 and 3, and the Eppler 432. Different comparisons has been performed.
The wing has been accurately adapted to ensure flight conditions between 0 and 5°. Optimal positioning of the EDF (Electric Ducted Fan) propellers has been evaluated for boundary layer ingestion according to first and second law of aerodynamics. Panel method and direct 3d simulations has been produced.
The result has been the design of a UAS that can flight at airspeeds lower than 15 m/s. The design of he drone has been evaluated including additional Coanda surfaces that ensure VTOL operations. An effective blended wing drone design is produced.
