Abstract:

Rotors and their associated dynamic components operate in high-cycle and environmentally harsh conditions. Accurate rotor load predictions are crucial part of rotor analysis and design. Lag damping poses a challenge for rotor load analysis due to the difficulty of incorporating lag damper effects into comprehensive rotor analysis. The key challenge in effectively predicting the lead-lag motions and resulting rotor loads is the lack of a high fidelity lag damper model. A high fidelity lag damper model that can predict damping forces over the operational range of a helicopter will benefit future rotor designs.
