Results of theoretical and experimental investigations are discussed for a broad class of three-dimensional separated flows around aircraft bodies and wings as well as around a whole vehicle configuration for transcritical and supercritical angle of attack areas. The experimental investigations are carried out in the MAI wind tunnels for Reynolds number values from the 0.26106-3.4106 м-1 region. Some general regularities are revealed for generation and transformation of separated flows and vortex systems. Relationships are found between a flow structure and shape of aircraft parts together with flow conditions for large angle of attack values. A possibility is discovered to use interaction of vortex structures in wing systems and vehicle configurations to enhance their lifting properties for large angle of attack values. It is demonstrated that a blowing of jets is an effective means to control a flow and aerodynamic characteristics of a vehicle for nonseparated or separated flows.
