 note = {Helicopters are used in various fields such as EMS (Emergency Medical Service), fire fighting, disaster relief, news report, and so on because of the capabilities of hovering and VTOL. However, noise, cost, and VFR (Vision Flight Rules) problems prevent helicopters from being widely used as a means of inter-city transportation in densely populated area. Prediction of the flow field of helicopter rotors in forward night is regarded as one of the most challenging problems in current computational fluid dynamics. Addition of the fuselage underneath the rotor further amplifies the complexity, requiring the solution of unsteady three-dimensional flows involving multiple bodies in relative motion. The periodic airloads, which is principally due to the rotating main rotor blades, impact the undesirable noise and vibration on the fuselage in the way of a mutual aerodynamic interference. Therefore, elaborate aerodynamic analyses of the rotor-fuselage interaction are needed to understand the physics and as an aid to the designers. In the preset study, three dimensional parallel Euler flow solvers have been developed for the simulation of unsteady rotor-fuselage interaction aerodynamics on both structured and unstructured grids using the ROBIN (ROtor Body INteraction) configuration. Validations with experimental data are conducted by simulating the flows around the ROBIN fuselage. The merit/demerit of each grid system is discussed., 資料番号: AA0049212004, レポート番号: JAXA-SP-05-017},
