How to Swoop and Grasp Like a Bird With a Passive Claw for a High-Speed Grasping

Dario Floreano, William John Stewart, Enrico Ajanic, Matthias Müller

There is a growing interest in unmanned aerial vehicles (UAVs) grasping, perching, and interacting with their surroundings by means of claws, arms, hooks, and other appendages. While multirotor vehicles can slowly lower onto a target object and grasp it, w ...

Prediction and Comparison of low-Reynolds Airfoil Performance

Vincent François-Charles Rolin, Eric Sauvageat

This semester project is aiming to compare different airfoils in order to select the most promising one as blade shape for scaled the straight-bladed giromills used in wind tunnel experiments. For this matter, a large amount of steady-state CFD-simulations ...

Aperiodicity in the near field of full-scale rotor blade tip vortices

Karen Ann J Mulleners, Kolja Kindler

Blade tip vortices are the dominant vortical structures of the helicopter flow field. The inherent complexity of the vortex dynamics has led to an increasing interest in full-scale in situ experiments, where the near field, closely behind the blade, is of ...
