2022年5月23日 · The MDO capability (still evolving) helped make the right kinds of trade-offs, i.e. "optimum compromises", in the design of the 787 and 777X. The improved CFD for air-loads prediction were coupled with FEA strength and stiffness optimization and these were used to guide direct optimization of aerodynamic shapes.

多学科设计优化（Multidisciplinary Design Optimization，MDO）是一种通过充分探索并利用工程系统中各学科间相互作用的协调机制来设计复杂系统和子系统的一种仿真方法，它在考虑各学科耦合和协同作用的基础上，通过采取有效的策略来寻求最优解，从而提高产品质量，缩短研制周期，特别适合处理类似航空发动机这样的复杂系统设计问题。 1974年，美国国家航空航天局（NASA）高级研究员索比斯基（Sobieski）提出MDO思想后，其广阔的工程应用前景吸引了 …

The Boeing 787 Dreamliner is an American wide-body airliner developed and manufactured by Boeing Commercial Airplanes. After dropping its unconventional Sonic Cruiser project, Boeing announced the conventional 7E7 on January 29, 2003, which focused largely on efficiency.

Boeing’s introduction of the 787 Dreamliner in 2004 signaled a significant departure from traditional commercial airplane manufacturing. With an airframe comprised of 50% carbon fiber reinforced plastic and other composites, the 787 entered history as the Boeing commercial airplane with the most extensive use of composite materials.

The 787 Dreamliner is designed and built with a sustainable product lifecycle in mind. Assembled in South Carolina at a net-zero emissions manufacturing facility, the primarily composite structure, advanced aerodynamics, and efficient engines deliver up to 25% lower fuel use and emissions compared to airplanes it will replace.

The design of complex aerospace systems is a multidisciplinary design optimization (MDO) problem involving the interaction of multiple disciplines.

2020年6月8日 · An efficient application of Bayesian optimization to an industrial MDO framework for aircraft design. The multi-level, multi-disciplinary and multi-fidelity optimization framework developed at Bombardier Aviation has shown great results to explore efficient and competitive aircraft configurations.

As shown in Fig. 4 (a) and Fig. 5 (a), we define their planforms based on Boeing 737-700 and 787-800 jets, respectively. We use the RAE2822 airfoil as the initial section shape in both cases, and...

2020年7月1日 · In Boeing’s 787 development model, the integration of sub-assemblies and final assembly was critical for the hardware and software from different suppliers to fit together and operate properly. This required a balance of providing autonomy to the suppliers to meet the design requirements and keeping a close oversight on the supplier processes.

2021年5月10日 · GitHub - Heavy-Division/B78XH: B78XH is an open source and free modification of default Boeing 787-10 in Microsoft Flight Simulator. I just realized that the 787 is only available in the Premium Edition MSFS2020, which I don’t have. Is that plane available for purchase separately? No, unfortunately. All we need now is a sound mod.
