The objective of the present study is to enhance the hovering efficiency of a UAV helicopter with a spherical fuselage under the effects of the fuselage size (Rf/R) and the distance between the fuselage and rotor (Hm/R), where R is the rotor radius. The RANS method combined with the k-ε turbulent model is used to model the airflow through the helicopter. The numerical model mentioned was well validated by comparing it with the results obtained in the literature.
