Abstract:

This report results from a contract tasking University of Manchester as follows A generic all-movable vertical tail will be designed at the conceptual design level with conventional and with active flexible technologies. The weight, performance and observable benefits of such designs will then be determined relative to the conventional design. The work will examine a range of different parameters including Mach number both sub and supersonic speeds, attachment position, yaw stiffness. The optimization will be carried out using either the La Grange code, which is already available at the University of Manchester, or the ASTROS code. A Finite Element model for a generic fin is available which was used in the DASA La Grange optimization code. This model was modified previously for the USAF-ASTROS optimization code. Part of the outcome of this work will be defining the best approach to use such multidisciplinary design and optimization codes to achieve an optimal aeroelastic design.
