 note = {Unsteady aerodynamics of two dimensional wing of NLR-7301 which has flap was numerically investigated with Navier-Stokes code in transonic region. Shock wave motion, unsteady lift and moment coefficients are analyzed for pitch and flap motion. It is observed that the nonlinearity of unsteady aerodynamic coefficients exists in very small amplitude range for pitch and flap forced motion. Those coefficients with small amplitude show stronger nonlinearity than those with larger amplitude. There is a reattachment of boundary layer, which is generated and vanished during the forced motion at a certain condition, down stream of the shock. This enlarges the nonlinearity in smaller amplitude motion. Deviation of the first order coefficients of the unsteady aerodynamics in small amplitude range shows it effects on the flutter boundary up to 10 percent in flutter index., 資料番号: AA0048469016, レポート番号: JAXA-SP-04-012},
