Development of uncertainty-based multidisciplinary design optimization tool for aircraft

飞机设计是一个极其复杂的过程，需要来自多个学科的专家设计师的共同努力，以达到满足所有要求的设计。正因为如此，飞机的初始设计是一个昂贵和耗时的过程。飞机设计师通常采用设计和优化方法，考虑从设计、制造、操作到寿命结束时的最终处置的飞行器生命周期的所有相关方面。在飞机设计分析、未来需求和技术以及环境和使用条件的各个学科中存在着大量的不确定性。因此，从飞机设计之初就考虑不确定性是很重要的。本研究建议的主要目标是评估和改进与飞机设计问题相关的各种不确定性的管理方法，并将其应用于多学科设计优化。该研究将为开发出更好的集成系统提供实践基础，以减少从设计到市场的开发成本和时间。这将提高新飞机设计的成功率，并允许更多的设计。

Aircraft design is an exceedingly complex process requiring the combined efforts of expert designers from multiple disciplines to arrive at a design that satisfies all imposed requirements. Because of this, aircraft initial design is a costly and time-consuming process. Aircraft designers generally take design and optimization methods with consideration of all relevant aspects of the vehicle lifecycle from design, manufacture, operation, to final disposal at the end of life. There exists a vast quantity of uncertainties arising from the various disciplines in aircraft design analysis, future requirements and technologies as well as the environmental and operational conditions. Therefore it is important to take uncertainties into account from the beginning of aircraft design. The main objective of this research proposal is to evaluate and improve methods for management of various uncertainties associated with the aircraft design problem with applications to multidisciplinary design optimization. This research will lead to provide a practical basis for well-developed integrated system that can reduce design-to-market development cost and time. This will increase the success rate of new aircraft design and will allow more designs to be pursued.
