内容記述 | Helicopter downwash interferes with the ground when a helicopter takes off or lands. By encountering this highly turbulent helicopter wake, two small fixed-wing aircraft were rolled over in the United Kingdom. Japan Aerospace Exploration Agency (JAXA) is investigating the helicopter wake structure in ground effect, especially in taxiing. This year JAXA is going to conduct a helicopter flight test to measure the downwash. Before the flight test, the helicopter downwash is analyzed by CFD in this study to decide the measurement conditions. Firstly, viscous effect on velocity profiles of the downwash is investigated in an isolated rotor analysis. As a result of the governing equations comparison, the flow field in Navier Stokes equations is more realistic than Euler equations. Secondarily, the downwash structures areinvestigated in a rotor-fuselage configuration by changing the taxiing speed. The differences between the downwash structures are clearly observed and the flow field leading to a brownout condition is simulated successfully. | |||||
