Feather-inspired flow control: The flow physics of spatially distributed covert flaps
Girguis Sedky, Ahmed Othman, Aimy Wissa
This study presents a novel spatially disrupted flow control system inspired by the covert feathers on bird wings. The system is a passive flow control system consisting of multipl…

A cyclic perspective on transient gust encounters through the lens of persistent homology
Luke Smith, Kai Fukami, Girguis Sedky +2
Large amplitude gust encounters exhibit a range of separated flow phenomena, making them difficult to characterize using the traditional tools of aerodynamics. In this work, we pro…

Experimental mitigation of large-amplitude transverse gusts via closed-loop pitch control
Girguis Sedky, Antonios Gementzopoulos, Francis D. Lagor +1
Air vehicles of all scales are susceptible to large-amplitude gusts that may lead to vehicle damage and instability. Therefore, effective physics-based control strategies and an un…
