CALCULATING THE AERODYNAMIC CHARACTERISTICS OF THE MAIN ROTOR IN CONSIDERATION OF THE INFLUENCE OF THE HELICOPTER FUSELAGE BY CFD METHOD
This paper presents an approach using the CFD method to build a calculated model for studying aerodynamic interaction between the main rotor and helicopter fuselage. The calculated model consists of two components which are the main rotor and helicopter fuselage, that is capable of determining the aerodynamic characteristics of the main rotor in consideration of the influence of the helicopter fuselage. The presented numerical method is very useful to simulate the velocity field and the airflow around the full helicopter, calculate the lift coefficient of the main rotor in the presence and absence of the induced influence from helicopter fuselage. The results of this study show a good agreement with data from other published work.
