This report results from a contract tasking School of Engineering University of Manchester as follows The contractor will investigate improvements in excitations signals used in aircraft flutter flight test data collection. It describes the work done during the period 1 April - 30 September 1998 for the EOARD contract F61775-98-WEO12 on Improved Flight Flutter Testing Excitation Techniques. Strategies. A number of improved swept sine Chirp and random excitation signals are developed and demonstrated to be superior to conventional linear sweeps and minimum crest factor random signals.
