A MULTI-SENSOR PARAMETRIC IDENTIFICATION PROCEDURE IN THE FREQUENCY DOMAIN FOR THE REAL-TIME SURVEILLANCE OF FLUTTER

Flutter flight tests is a crucial and feared phase of the flight test program of a new aircraft. The specific operational context of flutter surveillance implies the development of automatic and reliable tools operating in real-time. At ONERA, we recently developed a toolbox dedicated to data processing for flutter tests. It was used for the latest Airbus aircraft from the A340-600 up to the A380.In this article, we present the main procedure of the toolbox : the identification routine together with the graphical interfaces that were designed to help the operator to get a rapid knowledge of the identification results.
