Abstract : This memo documents the linear aerodynamic and thrust perturbation model of the X-29 simulation model resident in the Control Integration and Assessment Branch of Wright Laboratory (WL/FIGD) at Wright-Patterson Air Force Base, Ohio. This model was used to perform flying qualities evaluations of the X-29 aircraft at Wright Laboratory during the airplane's development in the early to mid-1980s. This work was conducted in order to document the X-29 longitudinal and lateral- directional linear aero model at numerous trim flight conditions for use in future research work in flying qualities. The X-29 is representative of typical fighter aircraft, even with its forward-swept wing, although the airframe is very unstable longitudinally. This memo is divided into four sections: Introduction, Definition of Terms, Explanation of Computer Printouts, and Computer Printouts sections. Definitions of all terms associated with the linear model are given in the Definition of Terms section. Explanation of all of the data in the computer printouts is given in the Explanation of Computer Printouts section. The Computer Printouts section contains the actual computer printouts for each trim flight condition.
