Originální abstrakt

This paper presents a study of the flutter characteristics of the benchmark supercritical wing. The wing is rigid, and the aeroelastic behavior is modeled by a mounting called the pitch and plunge apparatus. It allows the wing to move in a vertical direction and rotate around a pivot point. The simulations are performed using a high-fidelity computational fluid dynamics code coupled to a linear structural solver. The three major objectives of the presented work are the evaluation of the effect of a gas composition, a Reynolds number, and an angle of attack on a flutter boundary at subsonic and transonic Mach numbers. The gas composition effect is evaluated using R-12 coolant gas and air. The angle of attack is varied between 0 and 5 deg, thus covering both attached and separated flows.
