A MODEL TEST METHODOLOGY FOR THE INVESTIGATION OF AN ELASTICALLY SCALED MAIN ROTOR
要約
A methodology is presented for conducting a model wind tunnel test aimed at investigating a helicopter main rotor equipped with elastically scaled blades of a given full-scale prototype. Various model test conditions are considered, including aerodynamic and aeroacoustic studies. Key principles of developing the methodology are described based on analysis of the aerodynamic, strength, and frequency characteristics of a full-scale main rotor.
