This paper describes a series of ongoing experiments to capture the details of perpendicular vortex-airfoil interaction. Three test cases explored are: 1) a 21% thick symmetric airfoil at 1.1° angle ...

A team of evolutionary biologists and engineers have demonstrated a new structure inspired by shark skin that could improve the aerodynamic performance of planes, wind turbines, drones, and cars. The ...

Harvard scientists took inspiration from the shortfin mako, the fastest shark in the world, 3D printing its denticles to work as airfoils – aerodynamic-friendly structures. Harvard scientists have ...

Although many fixed-wing aircraft can withstand similar rapid pitch-up maneuvers, a vehicle subject to this dynamic stall process is not reliably controllable. Motivated by the lack of detailed ...

A shark’s natural ability to speed seamlessly through water could help us design next-generation aircraft and drones. Nature has always inspired engineers to overcome the hurdles of the human body, ...

Illustration of the airflow along an airfoil that exhibits leading-edge stall behavior. Notice the formation of a “short bubble” at a critical point along the leading edge. When the AOA is increased ...

To build more aerodynamic machines, researchers are drawing inspiration from an unlikely source: the ocean. A team of evolutionary biologists and engineers at Harvard University, in collaboration with ...
