Air Breathing Vehicles Integrated Design and Synthesis Environment

"An integrated design and synthesis environment based on an object-oriented, web-enabled, multidisciplinary framework supporting the engineering of Hypersonic Air-breathing Vehicles (HAV) is proposed. It facilitates vehicle development by integrating afeature-based modeling environment with low and high fidelity analyses and simulations for design and synthesis of HAVs covering the full flight regime from Mach 0 to 17. It integrates solid/surface-modeling, meshing, aerodynamics, propulsion, trajectory,weights, and vehicle closure analysis. Full 3D aerodynamic analysis over the entire vehicle will be supported. It enables the concurrent web-based engineering of HAVs by linking multiple users at distributed locations collaborating in real-time in thevehicle design and synthesis process. It implements a Common Computational Model, providing various levels of modeling and analysis fidelity while capturing the conceptual, preliminary, and detailed engineering methods. It automates and manages datatransfer and interaction among users, designs, analyses, and tools. The proposed development builds upon and leverages major successful programs already deployed and in use. A prototype environment will be developed and exercised in the collaborativedesign and analysis of an HAV facilitating thorough investigations of alternative vehicle configurations. It significantly enhances the overall engineering process for evaluating potential veh
