W-WING is whirl flutter aeroelastic demonstrator representing a half-wing with the nacelle, engine, and propeller. Two experimental campaigns were accomplished in past. Currently, it is intended for further experiments. For this purpose, the modification and upgrades were proposed. The paper describes the activities including the design, instrumentation, and aerodynamic and structural analyses.
