Abstract:Formation flight typically observed in migratory birds allows the trailing aircraft to benefit from surfing the updraft of the wingtip vortices generated by a leading aircraft. This results in higher lift and reduced fuel consumption for the trailing aircraft. However, the formation spacing in longitudinal, lateral, and vertical direction directly impacts the aerodynamics performance of the trailing aircraft. This paper aims to utilize computational fluid dynamics (CFD) tool -OpenFOAM, to capture the wake vort… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
