Séminaire Café (Interne)
Il s’agit d’un exposé assez court (20 min) et assez informel.
Prière aux conférencier·ère·s de ne jamais dépasser 30 min et de vérifier la compatibilité avec le projecteur avant le séminaire.
Les séminaires ont lieu les jeudis après la réunion du laboratoire qui débute à 13h30 dans la bibliothèque du labo sur le campus Jussieu, Barre Cassan, Bât A, 1er étage.

| 12 octobre | Esteban Valdecasa - LadHyX Physics of paragliding Paragliding is a relatively young adventure sport, popularized in the early 1980s, that involves flying lightweight, free-flying, foot-launched glider aircraft without a rigid primary structure. This design inherently leads to instability, particularly during unsteady phases of flight such as the spiral descent. A spiral descent is characterized by the helical trajectory of both the pilot and the wing around a shared axis. The maneuver poses unique dangers ; even without brake input, the pilot can remain trapped in a continuous spiral, descending at approximately 20 m/s. Measuring the position and orientation of a paraglider during such flight phases raises significant challenges regarding GPS precision and robustness against centrifugal acceleration. This study details how centimeter-level precision GPS and inertial measurement units (IMUs), combined with video recordings and sensor fusion techniques, enable the accurate reconstruction of the paraglider’s trajectory and attitude during a spiral descent. The methodology we present will be broadly applicable to large scale in-vivo measurements of complex unsteady dynamics. |
