ABSTRACT: In this effort, Intelligent Automation Inc. (IAI) in collaboration with the Stanford University proposes to develop a novel tool for advanced propulsion system design, in particular the open rotor system. The novel design architecture is an enhancement of the Collaborative Optimization technique. It allows discrete design choices and leverages on Variable Complexity Optimization to perform high-fidelity designs at moderate costs. The study of advanced propulsion systems is multidisciplinary in nature due to the aerodynamics, structures, acoustics and propulsion system coupling together, and recently there has been an emphasis on multi-design-point optimization. These are readily handled by the architecture. Moreover, since it becomes important to study the propulsion system design in context of the airplane (with the airframe integration an important challenge), such a design/analysis technology will be particularly useful. The architecture is completely modular in nature leveraging on our expertise in modeling and simulation and agent based systems, and allows any analysis code to be used for the different disciplines. The result of this study will help us understand the benefits of using open rotor technology compared to state of the art engines, and whether change of aircraft design itself will be required to realize the potential of such concepts. BENEFIT: The result of this proposed program is a design tool for advanced propulsion system design for use in all types of aircraft, including compound aircraft and civilian platforms, leading to improved performance and efficient operation across the vehicle performance envelope. The trade study conducted in this effort will also enable to make informed decisions about the feasibility of advanced propeller and open rotor designs which will be particularly beneficial to the airline as well as engine industry.
