... the methodology, experimental setup, and measurement techniques. The paper presents experimentally determined influence coefficients, and discusses the findings with regard to the aeroelastic design parameter “plunge-to-twist incidence ratio” (PTIR), which combines reduced frequency and torsion axis setback...

...Xu Dong; Yanfeng Zhang; Xingen Lu The blade mode shape and acoustic properties are important factors that affect the aeroelasticity of fan blades. The goal of this paper is to investigate the stall flutter mechanism associated with the first mode and its components. The paper numerically studies...

... identified in other studies was also observed in this paper. A new flutter risk frequency in which the blade frequency was less than the upstream cut-on frequency was found. The results showed that the effects of flow features and acoustic propagation characteristics on aeroelasticity were independent...

..., aeroelasticity also plays a major role. This manuscript addresses the not often discussed aeroelastic aspects of a new discrete type of passive self-recirculating casing treatment (RCT) designed for a transonic axial compressor stage. Experiments are carefully designed for synchronized measurement...
