Česká společnost pro mechaniku a Ústav termomechaniky AV ČR, v. v. i. vás srdečně zvou na přednášku prof. Ari Glezera z Woodruff School of Mechanical Engineering, Georgia Institute of Technology, USA.

Anotace: A novel, scalable approach to flight control by distributed fluidic modification of the apparent aerodynamic shape of the lifting surfaces, or virtual aerosurface shaping will be discussed. Robust control of attached and separated flows is engendered by leveraging the generation, accumulation, and advection of vorticity concentrations near the surface to alter its aerodynamic shape and thereby the aerodynamic forces and moments without mechanical control surfaces. Actuation is effected by the interactions of arrays of surface-integrated jets with the local cross flow such that the actuation time scale is typically considerably lower than the relevant characteristic time scale of the flow. The presentation will also describe applications of virtual aerosurface shaping to manoeuvring, drag reduction, and structural stabilization.
