Flapping Wings Amplify Pitch Stability: Insights from a Robotic Bird
Rónán Gissler, Kenneth S. Breuer
Using a flapping robot in a wind tunnel, we show that flapping faster amplifies existing longitudinal static stability (focusing on the pitch stiffness) and can even make an unstab…

Hydrodynamic loads and vortex evolution from a bio-inspired pectoral fin near a solid body
Xiaowei He, Kenneth Breuer
A fin-body configuration is tested in a water tunnel to study the hydrodynamic loads and vortex evolution under dynamic fin-flapping motions, which is an idealized approximation of…

Maneuvering of an underwater vehicle using bio-inspired pectoral fins
Pedro C. Ormonde, Xiaowei He, Kenneth Breuer
A Cyber-physical underwater vehicle is equipped with bio-inspired flapping fins positioned on the sides of the vehicle's main body. The proposed control surfaces are inspired by fi…
