Abstract

Results of studying the aerodynamic performance for a multipurpose medium lift helicopter model are presented. Both integrated and distributed aerodynamic performance of the model is presented along with flow distribution characteristics in the vicinity of the fuselage. The influence of two different rear fuselage geometries on the aerodynamic performance of the fuselage is discussed.
