dc.description.abstract The aviation industry is rapidly changing, lead by a growing demand on more modern aircrafts who are able to address the future challenges in terms of fuel consumption, effciency and green emissions among other factors. In order to correctly address these challenges, new technologies and non-conventional designs are being investigated upon. One of the phenomena which could be taken advantage of is the Boundary Layer Ingestion (BLI). Such phenomena take place whenever the propulsive system ingests an air ow which has been modified from the freestream conditions, either containing boundary layer ow from near aircraft features, or the more developed wake of a body. The aim of this paper is to gain a deeper insight on the parameters governing such phenomena. For such purpose, an experimental parametric study of a propeller performance ingesting the wake of three spheres at three different distances between them will be carried out on a closed loop wind tunnel. Results show that the distance between the propulsive unit and the bodies does not produce performance differences on the advance ratios range considered. However, the sphere size does produce changes on the system performance, either by increasing the produced thrust, or by decreasing the consumed power. The performance improvement mechanism is observed to depend on the sphere non dimensionalised size with the propeller diameter. For smaller spheres, a power reduction is observed, while for bigger ones thrust enhancement is produced.
