Abstract:

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
