Abstract Ground effect on rotary aircraft has been studied for many decades. Although a large body of research results is now available for conventional helicopters, this topic is just beginning to receive attention in the unmanned aerial vehicles community, particularly for small size UAVs. The objective of this papers is to assess the applicability on small rotary wing UAV of a widely-used ground effect model, developed in the middle of the last century by Cheeseman and Bennett, for predicting the ground effect on helicopters. Furthermore, other aerodynamics effects associated with flying close to surfaces or obstacles. Test stand has been designed to experiment with different configuration as walls, ceiling or combinations of them have been studied. A test stand has been designed for testing the aerodynamic effects with different configurations, and experiments with ground, ceiling and wall surfaces have been done. Also, experiments to assess the combined effect of ground+wall and the ground effect for a tandem rotor have been carried out. The experimental procedures and the implications on the obtained results is also included in the paper.
