Flutter analysis of structures is usually done in frequency domain. Alternately, time-domain methods have been suggested. For frequency-domain flutter analysis, flutter derivatives are used that can be identified from section model testing in th
The art of efficient extraction of these aeroelastic parameters requires an elastic suspension system to capture coupled displacement and aerodynamic force time histories from wind tunnel testing of section models. A novel three-degree-of-freedo
The extraction of flutter derivatives becomes more challenging when the number of DOF of section model increases from two to three. Since the work in the field of identifying all eighteen flutter derivatives has been limited, it has motivated th
For time-domain flutter analysis, Rational function approximation (RFA) approach involves approximation of the experimentally obtained flutter derivatives through 'multilevel linear and nonlinear optimization' procedure. This motivated the formu
