Abstract
The emergence of missiles flying in the hypersonic regime brings a new series of technical challenges such as, strong system integration of aerodynamics, propulsion and structures, and problems with thermal management. To address these challenges, a multidisciplinary integrated analysis tool which permits to perform a complete engagement simulation using a six-degree-offreedom flight mechanics models was developed. The tool is used to perform parametric study for missile sizing, performance trade-off and optimization. Additionally, it assesses the effect of vehicle design variables on the flight time, the trajectory and the velocity profile. A baseline missile reference was established as a starting point on which the impact of various design variables is assessed. The various sensitivity and trade-off analyses performed on key missile design variables allowed observing several interesting interactions and learning key lessons to apply to the design and analysis of hypersonic missiles. To demonstrate the application of optimization techniques to the design of hypersonic missiles, a simple time of flight optimization problem is presented. The multidisciplinary integrated analysis tool presents basic analysis capabilities for all subsystems critical to the study of hypersonic weapon systems. However, most subsystem models are limited in fidelity and details and would benefit from improvements. The most significant deficiencies are the lack of an airbreathing propulsion model an
