A Lightweight Device for Energy Harvesting from Power Lines with a Fixed-Wing UAV
Dario Floreano, William John Stewart
Modern UAVs (Unmanned Aerial Vehicles) suffer from restrictions in flight range and time due to battery capacity limitations. One way to overcome these limitations is to harvest energy from overhead power lines. A growing body of scientific literature has ...
IEEE2022Aerodynamic study of a Hyperloop pod equipped with compressor to overcome the Kantrowitz limit
This paper describes an investigation of the aerodynamic performance of a Hyperloop pod equipped with an axial compressor using CFD simulation. The compressor is expected to reduce the drag if the operational speed of the pod exceeds the Kantrowitz Limit ( ...
2021Nonlinear study on a rigid rotor supported by herringbone grooved gas bearings: Theory and validation
Jürg Alexander Schiffmann, Patrick Hubert Wagner, Philipp Kaspar Bättig, Wanhui Liu
The nonlinear behavior of a rigid rotor supported by herringbone grooved journal gas bearings (HGJBs) was investigated in this study. The two-dimensional narrow groove theory (2D-NGT) was adopted to model the HGJBs. A set of integrated rotor-bearing state ...
2021Bioinspired wing and tail morphing extends drone flight capabilities
Dario Floreano, Stefano Mintchev, Flavio Noca, Enrico Ajanic, Mir Alikhan Bin Mohammad Feroskhan
The aerodynamic designs of winged drones are optimized for specific flight regimes. Large lifting surfaces provide maneuverability and agility but result in larger power consumption, and thus lower range, when flying fast compared with small lifting surfac ...
2020Detecting Vortex Burst on a Rotating Low-Aspect Ratio Plate
This work experimentally examines the phenomenon of leading-edge vortex (LEV) burst in a low aspect ratio rotating plate. Through stereoscopic particle image velocimetry (SPIV) about chrodwise planes, the evolutionary track of the vortex is detailed from i ...
2015Vortical Flow Patterns for High Lift for High Speed Aircraft Concepts
Pénélope Leyland, Michele Gaffuri
Enhancing detached vortical flow over leading edges and flap surfaces allow high lift configurations in critical regimes of take-off and acceleration. In the context of the FP6 Environmentally Friendly High Speed Aircraft project HISAC, future high speed a ...
2013Hydrodynamics of a Pump-Turbine Operating at Off-Design Conditions in Generating Mode
Modern pump-turbines are subject to frequent switching between the pumping and generating modes with extended operation under off-design conditions. Depending on the specific speed of the pump-turbine, the discharge-speed as well as torque-speed generating ...
EPFL2012Modeling and Optimization of Terminal Airspace and Aircraft Arrival Subject To Weather Uncertainties
We develop an accurate model for the arrival traffic dynamics in terminal airspace that takes into account the weather forecast and runway configuration changes. The planning of runway configuration switching subject to weather constraints is formulated as ...
American Institute of Aeronautics and Astronautics2011Reynolds flocking in reality with fixed-wing robots: communication range vs. maximum turning rate
Dario Floreano, Jean-Christophe Zufferey, Sabine Hauert, Severin Leven, Maja Varga
The success of swarm behaviors often depends on the range at which robots can communicate and the speed at which they change their behavior. Challenges arise when the communication range is too small with respect to the dynamics of the robot, preventing in ...

Dario Floreano, Jean-Daniel Nicoud, Jean-Christophe Zufferey, Antoine Beyeler, Adam Klaptocz
We aim at developing ultralight autonomous microflyers capable of freely flying within houses or small built environments while avoiding collisions. Our latest prototype is a fixed-wing aircraft weighing a mere 10 g, flying around 1.5 m/s and carrying the ...
