FLUTTER OF LOW-ASPECT-RATIO WINGS PART II - AEROELASTIC MODEL DESIGN AND TESTING

摘要

Structural simulation in the design of aeroelastic models can be based on wing data in terms of influence coefficients or the distribution of stiffness parameters. The design of a doubly-flexible model of a low-aspect-ratio wing has previously been shown to be very difficult and cumbersome when based on influence coefficients. It is demonstrated in this report that the design of such a model when based directly on stiffness distributions and the analogy to an aeolotropic plate is both straightforward and successful. An improved technique of designing beam-like models from influence coefficient data is also presented.
