Modern aircraft system engineering strives to integrate subsystems into an efficient concept which responds to the needs of the vehicle's mission. As these designs become more tightly coupled, such that changes to a subsystem rapidly propagate through the vehicle, the design process must adapt to show the interactions between subsystems as early as possible in the design process, and to facilitate communication between traditionally separate engineering disciplines. The primary financial incentive for Aurora's development of this system is the increased productivity associated with use of the tool. Aurora completes on average 4 preliminary aircraft designs per year, each taking up to ½ a man-year. This tool is anticipated to speed preliminary analysis by as much as 50% as the system matures, with potential net benefit to Aurora of up to 50,000 per design. This tool is also expected to generate more business for Aurora by improving our turnaround for tightly coupled system engineering and increasing Aurora's ability to respond to needs in the military and civilian UAV markets.
The implementation of this architecture will speed turnaround time for NASA Dryden flight test safety simulation, and allow for rapid evaluation of design concepts and collaborative effort between disciplines and across geographical distances. The proposed framework will facilitate multi-disciplinary analysis by giving each discipline's preferred tool a common model source, and allow the results of one calculation to be rapidly integrated into another. The framework will allow systems engineers to ensure consistency between disciplinary analyses through the use of universal version control as applied to design changes. The framework will facilitate communication between geographically disparate users by allowing updated model data to be seamlessly pushed to various users, preventing outdated model data from being used for any new work. Additionally, the framework will give the engineer unprecedented access to complete system information during preliminary design, with a choice of display tools which is independent of the origin of the data.
