FLIGHT FLUTTER ANALYSIS USING FREQUENCY-DOMAIN SYSTEM IDENTIFICATION TECHNIQUES

摘要

In this paper frequency-domain estimators will be presented for application in the field of flight flutter analysis. Flight flutter tests are expensive and not without risks even when approached with caution. The complete session of flight tests must be as fast as possible but this often results in low quality data. Dedicated frequency-domain estimators will be presented to estimate and track the modal parameters as a function of the flight conditions.
