Features

Floating wind turbine and next-generation aircraft have high-aspect-ratio blade and wing that undergo nonlinear aeroelastic deformation. We have developed a nonlinear aeroelastic analysis framework with absolute nodal coordinate formulation (ANCF). This nonlinear aeroelastic deformation is coupled with multibody dynamics. We are also developing a novel analysis framework for this coupling dynamics.

Targeted Application(s)/Industry

Dynamic, aeroelastic, structural, vibration, aerodynamic analyses for Aeroelastic Multibody Systems:
1. Floating wind turbine
2. High altitude platform station (HAPS), high-aspect-ratio-wing commercial jet
3. Helicopter, drone
4. Robot, crane
