This paper presents static and dynamic wind-tunnel tests conducted on a 1/14-scale model of a transport aircraft to support flight-dynamic modelling in-stall and post-stall regimes. Experiments were performed at Cranfield University and ONERA using complementary test techniques. Results highlight hysteresis effects in static stall characteristics and demonstrate the dominant influence of rotation rate about the velocity axis on stall departure tendencies.
