In this work, it is investigated if the development version of the RSI package can be used for the identification of parametric models for the Puma SA-330 based on short 3211 fight test data records. The RSI package was applied to the real flight test data resulting from the Puma flight test maneuvers. Although the quality of the data base is poor, 8 transfer functions and two SIMO models describing the lateral decoupled dynamics of the helicopter could be identified. The dynamics compared favorably with those found by the WG18 members. Also 4 transfer functions and a MIMO model describing the short period helicopter dynamics were identified. Also, these dynamics compared well with the WG18 results. The models identified with the current version of RSI should be viewed as a black box containing the helicopter dynamics. They can be used to predict helicopter responses.
