Honlinger and published by . This book was released on 1982 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extensive research programs have been conducted at MBB and at AFWAL to investigate the application of active controls for the suppression of wing/store flutter. A flutter suppression system was developed and flight tested on an F-4F aircraft. The control law was designed by MBB using optimal control theory to minimize the control surface motion and to provide the required stability margins. During the test it was found that the dynamic behavior of the wing-pylon-store changed considerably with excitation amplitude due to free play and preload. The active flutter suppression system worked well and provided an increase in flutter speed. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of an analytical study directed toward the preliminary design of an adaptive flutter control system for fighter type aircraft carrying external wing mounted stores. The report develops and supports the following conclusions: (1) Active flutter control with acceptable stability margins is predicted for flight throughout the entire velocity- altitude envelope for store loadings both without symmetry. (2) An adaptive flutter control system, based on a digital evaluation of interrogated aircraft response data, appears to be feasible for use in gusty environments with small input test signal levels and after smoothing of the measured response data. (3) Hardware requirements and aircraft modifications are practical for fighter aircraft wing/store flutter control for frequencies up to approximately 20Hz. (4) The weight attributable to an operational flutter control system is estimated to be 131 lbs. In addition, plans are presented for semispan and full-span low speed and semispan transonic wind tunnel tests, 'Iron Bird' simulation tests, ground vibration and installed system tests, and flight test demonstrations with three store configurations having widely differing dynamic characteristics.

Download or read book Considerations on Wing Stores Flutter Asymmetry, Flutter Suppression written by ADVISORY GROUP FOR AEROSPACE RESEARCH AND DEVELOPMENT NEUILLY-SUR-SEINE (France) and published by . This book was released on 1978 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Air Forces in many countries have to face problems of aeroelasticity and flutter with aircraft carrying more and more stores. The two papers of this Report presented to the Sub-Committee on Aeroelasticity of the Structures and Materials Panel during the 46th Meeting of the Panel deal with two different aspects of the problem. The paper of A. Lotze is concerned with the many configurations, symmetric or asymmetric, that may occur and with their consequences on the natural modes of the structure. It clarifies the difficulties one has to face to clear the flight domain for all flight configurations and proposes useful approaches. The paper of C. Hwang, B.A. Winther, T.E. Noll and M.G. Farmer deals with the difficult problem of flutter suppression; it exposes the approach, the design, and the wind tunnel tests of the model of a fighter, carrying stores and equipped with a flutter suppression device. The two papers are of great interest to aeroelasticians and may give useful help to the designer. (Author).
