Abstract:

A method is presented for flight flutter testing employing a jet device to simulate the force effects of mass and to create thereby an apparent change in the mass distribution of an aerodynamic surface. This apparent mass change can be easily manipulated to make flutter come or go, and can therefore be used as a safe, fail safe, positive, flight flutter test device. A discussion of the basic principles of jet mass and its effect on flutter, and a description of the design details of two jet mass prototypes and a wind tunnel flutter model are presen ed. Author
