Abstract

The experimental technique of large amplitude dynamic setups is given. These setups are using to investigate unsteady aerodynamic characteristics at high angles of attack at low subsonic wind tunnel. The data processing technique and some experimental results are presented. The dynamic properties of separation flow development are investigated on the example of aerodynamic model with high aspect ratio wing large amplitude pitch oscillations. The investigation of regular and chaotic wing rock motion of slender delta wing is also presented
