pages 66 - 69, full text

W-WING is aeroelastic demonstrator representing a half-wing with the nacelle, engine, and propeller. It was adapted from the former aeroelastic model of a commuter aircraft. The demonstrator is used for the experimental research of whirl flutter aeroelastic phenomenon. Two experimental campaigns were accomplished in the frame of the previous project. Currently, the demonstrator is intended for further experiments in the frame of the OFELIA project. For this purpose, the modification of the demonstrator design and other upgrades were proposed. Submitted paper describes the preparatory activities including the demonstrator design, instrumentation, and aerodynamic and structural analyses. Gained experimental results will be subsequently utilized for verification of the analytical models and computational tools that will be used for development of the new power plant system, characterized as an open-fan concept, utilized for a new generation short-medium range turboprop aircraft.
