Keywords: high angle of attack, aerodynamics, modelling, time constant

Experimental and modelling results for nonlinear unsteady aerodynamics of 65, 70 degree delta wings and 80=60 degree double delta wing at high angles of attack are discussed, considering the characteristic time constants approach. The research is done in the framework of a joint collaborative programme between DERA Bedford, UK and TsAGI, Russia. In this paper the current state of the work is presented.
