A Robust Concept Exploration Method for Configuring Engines

小行星9612365 该奖项为研究和实施一种方法提供资金，该方法用于确定飞机、船舶和飞机发动机等按订单设计和按订单制造的系统的初始顶级规格。 该方法将侧重于划定满足设计目标但保留设计自由度的设计配置区域，直到获得足够的信息以选择单个配置进行进一步的设计定义。 研究方法将把现有的分析工具和稳健的设计原则，通常只在后期设计阶段实施，并将它们纳入产品实现时间线的早期阶段。有效应用 这些工具中的一部分将通过实验和统计技术（实验设计、方差分析和响应面方法）以及稳健设计技术的整合和实施来实现。 如果成功的话，这项研究的结果将使设计人员能够探索和确定许多替代的设计配置，并随后集中在一个单一的配置，以进一步分析和描绘。 由此产生的方法应有助于与（1）综合设计相关的成本效益研究（从多学科、系统的角度进行设计），（2）稳健设计（对沿着产品实现时间线的变化相对不敏感的设计），（3）灵活的设计（允许相对较小的变化被廉价地检查），（4）可修改的设计（允许设计以成本有效地适应总体要求的大变化）。 在产品实现时间线的早期阶段进行此类研究的能力对美国工业的商业和国防部门都有价值。

9612365 Mistree This award provides funding for the research on and implementation of a method for determining initial, top-level specifications of designed-to-order and made-to-order systems such as aircraft, ships, and aircraft engines. The approach will focus on the delineation of regions of design configurations that satisfy design goals but that retain freedom in the design until sufficient information is obtained to pick a single configuration for further design definition. The research approach will bring together existing analysis tools and robust design principles, generally implemented only in later design stages, and incorporate them in the early stages of a product realization time line. Effective application of these tools will be achieved through the integration and implementation of experimental and statistical techniques (design of experiments, analysis of variance, and response surface methodology) and robust design techniques. If successful, the results of this research will enable designers to explore and identify many alternative design configurations and subsequently focus on a single configuration for further analysis and delineation. The resulting method should facilitate cost-effective studies associated with (1) comprehensive design (design from a multidisciplinary, systems perspective), (2) robust design (designs that are relatively insensitive to changes along a product realization time line), (3) flexible design (allow relatively small changes to be examined inexpensively), (4) modifiable design (allow designs to be adapted to large changes in overall requirements cost-effectively). The capability to perform such studies in the early stages of a product realization time line should be of value to both the commercial and defense sectors of US industry.
