Opis

This volume contains a thorough description of the EU-supported project EUROSHOCK II concerned with the investigation of active shock and boundary layer control to improve aircraft performance. Discussed are basic experiments, supplemented by Navier-Stokes computations, to improve and validate physical models relevant to control and the extension, validation and application of various computational methods to airfoil and wing flows with control. Furthermore described are experiments on airfoils and wings carried out to assess the aerodynamic benefits of control and to provide data for validation purposes. Finally, control applications to real aircraft and the corresponding installation penalties and mission benefits are addressed. This volume is a sequel to Vol. 56 on passive shock control.
