JFLUTTER REAL TIME FLUTTER ANALYSIS IN FLIGHT TEST

Abstract

During the development of an aircraft it is mandatory to demonstrate that the aircraft is free from flutter within its operational flight envelope. This piece showcases JFlutter, a flutter analysis tool developed within Airbus Defence & Space Flight Test Analysis Tools. JFlutter allows the analysis of this phenomenon in real time monitoring and post flight mode. Using the FxS dataserver as data provider, a reliable data gathering mechanism has been used for this critical tool. As flutter means aero elastic instability, potentially dangerous, flight safety becomes a main requirement. For safety reasons and in order to reduce overall test program duration it is necessary to check predicted frequencies and damping in real time / monitoring.
