Interactive Flutter Solver at ARL.

Abstract

An interactive direct flutter solving routine has been installed on ARL's ELXSI computer. Interactive graphics routines, using DI-3000 graphics, software, have been incorporated to give the user a progressive picture of the solution. Estimates of subcritical response data may also be determined using this method. A description of the method and the associated software is presented here. Also included is a two-dimensional flutter problem, using quasi-steady aerodynamics, which is solved by this direct flutter solver. Keywords: Aeroelasticity; Flutter; Differential equations; Computer programs; and Australia.
