That’s all it took to inspire Flavio Noca, who at the time was a graduate student in Caltech’s Aeronautics Department, and now teaches aerodynamics at the University of Applied Sciences Western Switzerland (hepia) and the Swiss Federal Institute of Technology (EPFL), to explore leveraging penguins’ “rocket” properties to create new propulsion technologies with high maneuverability and improved hydrodynamic efficiency.
At the American Physical Society’s (APS) Division of Fluid Dynamics meeting, Nov. 24 – 26, in Pittsburgh, Pa, Noca will present a penguin-inspired propulsion system that uses a novel spherical joint mechanism developed and manufactured by Bassem Sudki, a research assistant within Noca’s aerodynamics group, under the supervision of Professor Michel Lauria who leads hepia’s Robotics Laboratory.
Based on a penguin’s shoulder-and-wing system, the mechanism features a spherical joint that enables three degrees of freedom and a fixed center of rotation. “Unlike an animal shoulder joint, however, this spherical joint enables unlimited rotational range about the main shaft axis like a propeller,” Noca said.
