Aug 17,  · Books. AIAA Education Series; Library of Flight; Flight Test Conference Home; No Access. Frequency-domain identification of XV tilt-rotor aircraft dynamics. Identification and verification of frequency-domain models for XVtilt-rotor aircraft dynamics in cruising flight. A nonparametric frequency-response approach is used which does not depend on assumed model order or structure. Transfer-function representations are subsequently derived which fit the frequency responses in the bandwidth of greatest concern for piloted Author: Mark B. Tischler. Models of the open-loop hover dynamics of the XV Tilt-Rotor Aircraft are extracted from flight data using two approaches: and the identification results are presented and compared in detail. ably, with the differences associated mostly with the inherent weighting of each technique.
