M4 Engineering proposes to implement physics-based, multidisciplinary analysis and optimization objects that will be integrated into a Python, open-source framework and used in a wide variety of simulations. The integrated objects will perform discipline-specific analysis across multiple flight regimes at varying levels of fidelity. The process will also deliver system-level, multi-objective optimization. Addressing physics-based, system-level objectives that span more than one discipline will have profound effects on improving decision-making abilities during the conceptual design phase when evaluating advanced technological concepts. In the proposed effort, existing capabilities will be leveraged to create a high fidelity, physics based, multidisciplinary analysis and optimization (MDAO) system. This proposed work will compliment M4 Engineering's expertise in developing modeling and simulation toolsets that solve relevant subsonic, supersonic, and hypersonic demonstration applications.
