Numerical and Experimental Analysis and Energy Model of a High Camber Wing 2018-01-1955

This paper presents a coupled numerical and experimental study of an unconventional wing profile such as cp-180-050-gn (Cambered plate C=18% T=5% R=0.78). This wing profile deals with low speeds and is not currently used on any aircraft model. Otherwise it presents interesting performances that can be exploited for design of low speed STOL or VTOL aircraft by mean of the very high lift that it can generate and it simplicity which can fit with VAWT, drones specifically designed for low speed operations and cyclorotors. After a preliminary CFD assessment of the wing a complete experimental characterization also at high angles of attack has been performed. The excellent agreement between CFD and experiments has allowed producing a complete analysis of the behavior of the wing profile both before and after stall conditions. This study has the key objective of analyzing the viability of such an unconventional wing in traditional or over-stalling conditions. A complete modeling of the specific wing is produced with the definition of its potential deployment into unconventional aircraft architectures and into both Darreius and Savonius wind turbines.
