In this laboratory, coupled analysis between structural and fluid dynamics is mainly conducted to analyze the aeroelastic characteristics of various vehicles, including turbomachinery. Regarding rotorcraft, CSD/CFD coupled analysis and multidisciplinary design optimization of the active rotor blade such as active trailing edge flaps are being studied. Regarding the fixed-wing aircraft, aeroelastic analysis for the mid/high-altitude unmanned vehicles is being studied. Recently, analysis and experiment for high speed vehicle and its launcher, space launch vehicle, insect-inspired flapping wing micro air vehicle are being conducted. Also, CFD/CSD coupled analysis for turbine blade, EDucation-research Integration through Simulation On the Net(EDISON), rotor blade design and analysis for a delivery drone are being conducted.
