"Fluid dynamical interactions in organized bird flock flight" G. Vitucci, 01/03/19 (MEED seminar)

Collective flight of birds has kept humans puzzled for millennia. Nevertheless the first attempts at studying it in a rigorous framework have been carried out only during recent decades. Among the most asked scientific questions is the aerodynamic advantage of certain observed flock topologies and dynamics for long distance journeys. In order to quantify the inter-individual mechanical interaction we develop a novel computational approach which is inspired to the well established lifting line method used in fixed-wing aircraft studies.

"A (multiple-)shooting approach aimed to study nonlinear dynamics of bird flight", G. Ducci, 15/03/19 (MEED seminar)

Gianmarco gave an overview about the mathematical tool he has been developing, aimed to study trimmed configuration of bird flight. 

Within the seminar, he presented the validation of the Multiple-shoting code, and its application in order to study flight dynamics equations of motion.

"Flapping for migrating: energy expenditure quantification" by G. Vitucci, 27/08/19 (ASAB 2019)

Gennaro presented his joint work with Philippe Chatelain and Renaud Ronsse during this years' exciting conference organized by the Association for the Study of Animal Behaviour.

Modern high-resolution technology allows tracking migrating birds over long distances. Depending on species, duration of displacement, environmental conditions, social organization, etc., different flock topology and flight dynamics arise.

The current work focuses on flapping flight. In particular, it intends to unveil observed flock spatio-temporal synchronization through the quantification of the mechanical power required for flying in group - and related disparity in energy consumption between leader and follower.

 

The RevealFlight Project

The RevealFlight project aims at shedding light on the efficiency optimization mechanisms deployed by biological flyers. We will focus on birds, and in particular on migratory birds, which are known to exhibit such efficiency-seeking mechanisms at several levels, while maintaining relatively stable flight conditions, leading to impressive results.
