Objectives• Understand the nonlinear dynamics, stability, and control of various biomimetic flapping wing designs featuring
• Analysis of wing flexibility
• Consideration of wing mass
• Non-naïve averaging methods
• Primary focus area: determine the influence of wing flexibility on
the stability of flapping wing designs and optimal stiffness, mass, and wing loading for aerodynamic performance and stability
• Develop robust nonlinear control strategies for this nonlinear, time periodic system across the entire
flight envelope
Approach - Multi-fidelity Analysis | Motivation - BumblebeesAchievements•Developed
full multi-body mathematical model for multiple winged insects/vehicles from
first principles and verified the result against other models in the literature
•Developed
aerodynamic pitching moment predictions based on both unsteady aerodynamic
theory and full direct numerical simulation of the incompressible Navier Stokes
equations
•Implemented
