Daniele is an Aerospace Engineer, specialised in Aerodynamics. He attained his Master’s degree in Aerospace Engineering from Universita' di Pisa in 2017. He developed his final year project during a six-month internship in Dr Viola’s lab, under the supervision of Dr Viola, Dr Cummins and Prof Camarri. He investigated both experimentally (terminal velocity measurements with motion tracking) and numerically (direct numerical simulations) the aerodynamics of the dandelion fruit. This study received the Pegasus Award for a Special Achievement through Working Abroad for Academic Research.
In September 2017, he started his PhD at the University of Edinburgh under the supervision of Dr Viola, Dr Nakayama, Dr Mastropaolo, Dr Cummins and Dr Francesco Giorgio-Serchi. It studies the incredible flight capacity of Alsomitra macrocarpa which inspired Igo Etrich to build the first military plane mass-produced in Europe. Unlike many gliding seeds which use auto-rotation, it shows a stable gliding flight with a rate of descent slower than rotating seeds and a distance covered of hundreds of meters. The characterization of the phugoid mode and a stable flight in turbulent air are key research questions, that will be answered using computational fluid mechanics, flow visualization and particle image velocimetry (PIV) of real seeds and artificial replicas. This PhD aims to give insights into the design of MAVs, used for instance in weather forecasting, agriculture and space exploration.
