Analysis of Pitot tube Airflow Velocity Sensor Behavior in Blockage Situations

Several airplanes crashes throughout the past decades are linked to the failure of the airplane flow velocity sensor known as pitot device or pitot tube. The study of its behavior in blockage, either due to human errors or due to environmental factors, cou ...

Time-Continuous Phosphorus Flows in the Indian Agri-Food Sector: Long-Term Drivers and Management Options

Claudia Rebeca Binder Signer

Phosphorus (P) is a major agricultural nutrient and, in its mineable form, a potentially scarce resource. Countries with limited physical access to P should hence develop an effective national P governance. This requires analyses of trends and variations i ...

Advanced Instrumentation for Measuring Fluid-Structure Coupling Phenomena in the Guide Vanes Cascade of a Pump-Turbine Scale Model

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

In the present study, the fluid-structure coupling is investigated in the guide vanes of a pump-turbine scale model placed in one of the test rigs of the Laboratory for Hydraulic Machines (EPFL) in Lausanne. The paper focuses on the advanced instrumentatio ...

A 10-gram Vision-based Flying Robot

Dario Floreano, Jean-Christophe Zufferey, Jean-Daniel Nicoud, 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 ...

Hydrodynamics of the free surface flow in Pelton turbine buckets

Alexandre Perrig

The design of Pelton turbines has always been more difficult than that of reaction turbines, and their performances lower. Indeed, the Pelton turbines combine 4 types of flows: (i) confined, steady-state flow in the piping systems and injector, (ii) free w ...

A 10-gram Microflyer for Vision-based Indoor Navigation

Dario Floreano, Jean-Christophe Zufferey, Jean-Daniel Nicoud, Antoine Beyeler, Adam Klaptocz

We aim at developing ultralight autonomous microflyers capable of navigating within houses or small built environments. Our latest prototype is a fixed-wing aircraft weighing a mere 10 g, flying around 1.5 m/s and carrying the necessary electronics for air ...
