A unique unsteady cascade experiment directed at providing fundamental aerodynamic data needed to verify or direct refinements to the basic model on unstalled supersonic torsional flutter in turbomachines is presented. In particular, the steady, quasi-static, and unsteady aerodynamics were determined for a multiple circular arc (MCA) airfoil cascade which modeled the tip section of an advanced design fan blade. The MCA cascade was harmonically oscillated in the torsional mode at a reduced frequency value of 0.14. The fundamental unsteady aerodynamic data was obtained at a Mach number equal to 1.55 over a range of interblade phase angles for two values of the cascade static pressure ratio. These unsteady results were then correlated with the predictions from state-of-the-art unsteady flat plate cascade analyses.

Download Research on Aeroelastic Phenomena in Airfoil Cascades; An Experimental Investigation of the Unsteady Aerodynamics of a Classical Airfoil Cascade in Translation Book in PDF, ePub and Kindle
The advent of high tip-speed, high work, blading in the fan stages of advanced gas turbine engines has led to the recognition of a new type of blading instability - unstalled supersonic flutter. As a result, a concerted effort to develop an appropriate predictive mathematical model has taken place. To determine the range of validity and to direct refinements to the basic flow model, fundamental supersonic oscillating cascade data are required. The experiment described herein is directed at significantly extending the range of existing supersonic cascade data to include translation mode oscillations. In particular, the fundamental time-variant translation mode aerodynamics are determined for the first time for a classical airfoil cascade in supersonic inlet flow field over a range of interblade phase angles at a realistic reduced frequency value. These unique experimental data are then correlated with predictions obtained from an appropriate state-of-the-art harmonically oscillating flat plate cascade aerodynamic analysis. (Author).

The advent of high tip, high work, blading in the fan stages of advanced gas turbine engines has led to the recognition of a new type of blading instability - unstalled supersonic flutter. As a result, a concerted effort to develop an appropriate predictive mathematical model has taken place. To determine the range of validity and to direct refinements to the basic flow model, fundamental supersonic oscillating cascade data are required. This is the report for an experimental research program directed at obtaining these unique time-variant aerodynamic data. The approach involved harmonically oscillating dynamically instrumented 2-D rectilinear cascades of airfoils in a supersonic inlet flow field, with the unsteady operation of the cascade computer controlled. Data were obtained in both torsion and translation over a range of steady and time-variant aerodynamic conditions. All of these data were then correlated with predictions obtained from a current state-of-the-art model.
