In this method, a comprehensive integral rotor code, CAMRAD 2 (Comprehensive Analytical Model of Rotorcraft Aerodynamics and Dynamics), and an unsteady Euler code are used as the aerodynamic and the CFD code respectively. This method is applied to the calculation of rotor aerodynamics in a high-speed forward flight condition and a descending flight condition. The calculated pressure distributions on the blade surface are in good agreement with experimental data in the high-speed forward flight case. In this case, analyses are conducted not only for a rectangular tip shape but also for simply modified tip shapes. It is indicated that the coupling method is required for the calculation of modified tip shapes. In the descending flight case, it is also shown that the present method is required. In addition, the acoustic pressure of Blade-Vortex Interaction (BVI) noise is calculated. It is indicated that the coupling method is not always required for the prediction of BVI noise in this case.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
