Abstract
In Part I of this work, a theoretical simulation study of rotor blade response to turbulence in forward night is presented. For verification of this theoretical computational method, a new experimental method b ased on a special gust field generated by a rotating slotted cylinder with an airfoil (RSC/airfoil) in a wind tunnel is developed to simulat e the aerodynamic environment of a rotating rotor blade in forward fli ght. This gust generator can produce a single harmonic gust wave and a lso turbulence with uniform power spectral density over a certain freq uency band in the lateral and longitudinal directions. In this article , quantitative comparisons are also made with theoretical results for both random and nonrandom parametric excitation. The quantitative agre ement between theory and experiment indicates that this experimental m ethod is useful.
