Abstract

A high-lift configuration of the civil aircraft including body, wing in high-lift configuration, nacelle and pylon is considered in the present work. Numerical simulations of the flow have been carried out in the framework of Reynolds averaged Navier-Stokes (RANS) equations for Mach number of 0.2. The passive and active flow control methods, which are capable to improve maximal lift of the aircraft, have been considered. The influence of strakes installed on the nacelle and on the body as well as jet blowing on aerodynamic characteristics has been investigated.
