Treatment is given of system response evaluation, especially in application to subcritical flight and wind tunnel flutter testing of aircraft. An evaluation is made of various existing techniques, in conjunction with a companion survey report. Theoretical and analog experiments are made to study the identification of system response characteristics. Various input excitations are considered. New techniques for analyzing response are explored, particularly in reference to the prevalent practical case where unwanted input noise is present, such as due to gusts or wind tunnel turbulence. Further developments are also made of system parameter identification techniques.
