The Influence of Composite Induced Couplings on Tiltrotor Whirl Flutter Stability

摘要

The paper presents a study of the influence of composite induced elastic couplings in the stability characteristics of a wing/rotor system. In particular, the study is focused on the effectiveness of the composite couplings that are introduced to the wing and the blade structures in modifying tiltrotor whirl flutter stability in forward fight(airplane ode). For that purpose, the study was first concentrated on the modeling and tailoring of the composite wing and blade structures.
