This book was released on 1978 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flight data from a 60 deg. delta wing aircraft have been analysed using a modified Newton-Raphson parameter estimation procedure. The model equations used for the analysis were extended to account for incidence vane errors and non-linearities in the pitching moment curves. Longitudinal derivatives extracted from the data have been compared with wind tunnel measurements and some theoretical estimates and areas of agreement and disagreement identified. The results demonstrate the usefulness of the parameter identification method not only for the validation of aircraft mathematical models and for checking flight results against wind tunnel data but also for obtaining aerodynamic data not easily available through other means.

Book Synopsis Evaluation of High-angle-of-attack Handling Qualities for the X-31A Using Standard Evaluation Maneuvers by : P. C. Stoliker
Download or read book Evaluation of High-angle-of-attack Handling Qualities for the X-31A Using Standard Evaluation Maneuvers written by P. C. Stoliker and published by . This book was released on 1996 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The X-31A aircraft gross-acquisition and fine-tracking handling qualities have been evaluated using standard evaluation maneuvers developed by Wright Laboratory, Wright-Patterson Air Force Base. The emphasis of the testing is in the angle-of-attack range between 30° and 70°. Longitudinal gross-acquisition handling qualities results show borderline Level 1/Level 2 performance. Lateral gross-acquisition testing results in Level 1/Level 2 ratings below 45° angle of attack, degrading into Level 3 as angle of attack increases. The fine-tracking performance in both longitudinal and lateral axes also receives Level 1 ratings near 30° angle of attack, with the ratings tending towards Level 3 at angles of attack greater than 50°. These ratings do not match the expectations from the extensive close-in combat testing where the X-31A aircraft demonstrated fair to good handling qualities maneuvering for high angles of attack. This paper presents the results of the high-angle-of-attack handling qualities flight testing of the X-31A aircraft. Discussion of the preparation for the maneuvers, the pilot ratings, and selected pilot comments are included. Evaluation of the results is made in conjunction with existing Neal-Smith, bandwidth, Smith-Geddes, and military specifications.

Download or read book Linearized Poststall Aerodynamic and Control Law Models of the X-31a Aircraft and Comparison with Flight Data written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-07-08 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: The X-31A aircraft has a unique configuration that uses thrust-vector vanes and aerodynamic control effectors to provide an operating envelope to a maximum 70 deg angle of attack, an inherently nonlinear portion of the flight envelope. This report presents linearized versions of the X-31A longitudinal and lateral-directional control systems, with aerodynamic models sufficient to evaluate characteristics in the poststall envelope at 30 deg, 45 deg, and 60 deg angle of attack. The models are presented with detail sufficient to allow the reader to reproduce the linear results or perform independent control studies. Comparisons between the responses of the linear models and flight data are presented in the time and frequency domains to demonstrate the strengths and weaknesses of the ability to predict high-angle-of-attack flight dynamics using linear models. The X-31A six-degree-of-freedom simulation contains a program that calculates linear perturbation models throughout the X-31A flight envelope. The models include aerodynamics and flight control system dynamics that are used for stability, controllability, and handling qualities analysis. The models presented in this report demonstrate the ability to provide reasonable linear representations in the poststall flight regime.
