ABSTRACT	A personal computer based,on-line time series analysis system is described which estimates the flutter boundary and vibration-mode parameter of a flutter model.The system software is written is BASIC and uses an autoregressive process.Ground vibration and wind tunnel flutter tests were conducted on supersonic delta wing models to enable system evaluation.Stationary random response of the wings was subsequently applied into the system and its practical use was confirmed using the estimated results.
