RELATIONSHIP BETWEEN FLUTTER PARAMETERS AND GENERALIZED AERODYNAMIC FORCES FOR WINGS OF LOW ASPECT RATIO

Abstract

A set of closed-form approximations is derived which relates the flutter conditions of a wing to its generalized aerodynamic forces. A simplified two-mode analysis is used to obtain a firstorder approximation. More general analyses are performed by treating additional effects as perturbations. The derivations are applicable to a wide class of low-aspect-ratio wings and apply to subsonic, transonic, supersonic, and hypersonic flow. (Author)
