Multiple-Surrogate Approach to Helicopter Rotor Blade Vibration Reduction

摘要

The advantages of using multiple surrogates for approximation and reduction of helicopter vibration are studied. Multiple approximation methods, including a weighted-average approach, are considered so that pitfalls associated with only using a single best surrogate for the rotor blade vibration-reduction problem are avoided. A vibration objective function corresponding to a flight condition in which blade-vortex interaction causes high levels of vibration is considered.
