dc.description.abstract |
Flutter clearance is usually regarded as a two step process: flutter analysis (including ground vibration testing, aerodynamic analysis and equation of motion solution), and flutter flight testing. The problem with this approach is that there are often significant discrepancies between the predicted damping and frequency trends and the trends measured during flutter flight testing. The discrepancies, when they become apparent during flight testing, cast doubt on the accuracy and validity of the analysis and hamper processing of the flight test data. By employing relatively simple techniques in combination, the analyst can be much better prepared for the flutter flight tests, enabling him to process the data efficiently despite the usual discrepancies and to better judge whether the discrepancies indicate serious deficiencies in the flutter analysis. |
