Development of Advanced Techniques for the Identification of V/STOL aircraft Stability and Control Parameters

Abstract

Contemporary analyses of transition flight of V/STOL aircraft are based on aerodynamic data measured in a wind tunnel or on analytical prediction using methods developed for conventional aircraft. The validity and accuracy of these techniques for V/STOL aircraft has not yet been established, and it is essential that they be correlated with flight test data through parameter identification. In spite of the complicated nature of V/STOL dynamics in transition, some method of identifying these characteristics is required. This report documents the development of identification techniques to meet this requirement. The report first presents the selection of a mathematical model to represent a V/STOL aircraft (the X-22A). This is followed by a discussion of available identification techniques. Based upon a thorough knowledge of the requirements of this program and the limitations of the available techniques, advanced techniques suitable for identification of V/STOL aircraft stability and control parameters are developed.
