Earwig-inspired foldable origami wing for micro air vehicle gliding

Foldable wings serve as an effective solution for reducing the size of micro air vehicles (MAVs) during non-flight phases, without compromising the gliding capacity provided by the wing area. Among insects, earwigs exhibit the highest folding ratio in thei ...

Bioinspired morphing wings for extended flight envelope and roll control of small drones

Dario Floreano, Stefano Mintchev, Flavio Noca, Grégoire Hilaire Marie Heitz, Matteo Di Luca

Small-winged drones can face highly varied aerodynamic requirements, such as high manoeuvrability for flight among obstacles and high wind resistance for constant ground speed against strong headwinds that cannot all be optimally addressed by a single aero ...

Large Eddy Simulation of the Rotating Stall in a Pump-Turbine Operated in Pumping Mode at a Part-Load Condition

François Avellan, Olivier Pacot, Chisachi Kato

The investigation of the rotating stall phenomenon appearing in the HYDRODYNA pump-turbine reduced scale model is carried out by performing a large-scale large eddy simulation (LES) computation using a mesh featuring approximately 85 x 10(6) elements. The ...

Performance analysis of jump-gliding locomotion for miniature robotics

Dario Floreano, Mirko Kovac, Jean-Christophe Zufferey

Recent work suggests that jumping locomotion in combination with a gliding phase can be used as an effective mobility principle in robotics. Compared to pure jumping without a gliding phase, the potential benefits of hybrid jump-gliding locomotion includes ...

Experimental Evidence of Rotating Stall in a Pump-Turbine at Off-Design Conditions in Generating Mode

François Avellan, Mohamed Farhat, Vlad Hasmatuchi, Steven Roth, Francisco Botero

An experimental investigation of the rotating stall in reduced scale model of a low specific speed radial pump-turbine at runaway and turbine brake conditions in generating mode is achieved. Measurements of wall pressure in the stator are performed along w ...

Towards the Self Deploying Microglider; Gliding Flight and Bioinspired Wing Folding Mechanism

Dario Floreano, Mirko Kovac, Jean-Christophe Zufferey, Grégory Savioz

The Self Deploying Microglider project aims at developing a novel palm sized robot that can climb up walls, deploy itself into the air, recover from every position in air and perform subsequent goal directed gliding and attachment to walls. So far, we deve ...

A 1.5g SMA-actuated Microglider looking for the Light

Dario Floreano, André Guignard, Mirko Kovac, Jean-Christophe Zufferey, Jean-Daniel Nicoud

Unpowered flight can be used in microrobotics to overcome ground obstacles and to increase the traveling distance per energy unit. In order to explore the potential of goal-directed gliding in the domain of miniature robotics, we developed a 22cm microglid ...
