Abstract

Hydroelastic instabilities, such as static divergence and flutter, are major concerns for the safe operation of next-generation self-twisting composite marine rotors. In this paper, an efficient theoretical model was developed to obtain a first-order estimation of the static divergence speed of such rotors. The model was inspired by classical aeroelasticity theory and furnished with advanced numerical modeling. Its application to the marine environment was illustrated via a self-twisting composite propeller. The methodology is equally applicable to other structures, such as tidal and wind turbines.
