The system consists of a Navier-Stokes solver for near rotor flowfield computation and an acoustic wave equation solver for computing sound pressure propagation. The Navier-Stokes solver is applied on a system of overset grids in order to allow realistic motion of the rotor blades. The acoustic equation used is the linear Ffowcs Williams and Hawkings equation in Farassat's 1A integral formulation. For aerodynamic validation, results obtained from Caradonna's test rotor in hover and AH-1G OLS rotor in forward flight are presented. For aeroacoustic validation, sound pressure history obtained from 1/4 scale UH-1 rotor in hover is presented.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
