挑战
与许多航空航天工程公司一样，TLG 采用领先的行业应用 STAR-CCM+ 来执行 CFD 仿真。 TLG 使用该应用程序对飞机进行空气动力学模拟，并预测机身周围的压力和温度。但是，该公司希望降低与运行模拟相关的成本。 TLG Aerospace 的工程经理 Andrew McComas 说：“我们使用云提供商来托管我们的模拟，但每次模拟的成本很高。” “运行一个典型的模拟每个案例要花费我们数百美元，每个项目可能有数百个案例。”
TLG 还希望能够扩展其高性能计算 (HPC) 应用程序以进行更大规模的模拟。 “我们行业的趋势是进行需要更多计算资源的更复杂的模拟，”McComas 说。 “但是对于我们使用的内部 HPC 集群，我们可以运行的最大大小问题是有限的。我们仅限于少数节点，无法分配足够的内存来运行大规模问题。”
因为想要降低成本并获得可扩展性，TLG 决定寻找新的云提供商。

解决方案
TLG 使用 Amazon Simple Storage Service (Amazon S3) 存储桶在云上存储数 TB 的模拟数据。该公司还利用了 Amazon Elastic Block Store (Amazon EBS)，它提供了可与 Amazon EC2 实例一起使用的持久块级存储卷。 TLG 将 Amazon EBS 卷用于 HPC 集群头节点。此外，TLG 使用 Amazon CloudWatch 监控服务在在线 AWS 控制台中跟踪 CFD 模拟的进度。 “我们创建了一个 CloudWatch 指标，使我们能够直接从 AWS 监控模拟状态，”McComas 说。 “因此，我们可以从任何计算机监控解决方案，而无需使用 CFD 代码的专有 GUI。”

Airbus Soars with Wearable Technology
Building an Airbus aircraft involves complex manufacturing processes consisting of thousands of moving parts. Speed and accuracy are critical to business and competitive advantage. Improvements in both would have high impact on Airbus’ bottom line. Airbus wanted to help operators reduce the complexity of assembling cabin seats and decrease the time required to complete this task.

Aerospace & Defense Case Study Airbus
For the development of its new wide-body aircraft, Airbus needed to ensure quality and consistency across all internal and external stakeholders. Airbus had many challenges including a very aggressive development schedule and the need to ramp up production quickly to satisfy their delivery commitments. The lack of communication extended design time and introduced errors that drove up costs.

Accelerate Production for Spirit AeroSystems
The manufacture and assembly of massive fuselage assemblies and other large structures generates a river of data. In fact, the bill of materials for a single fuselage alone can be millions of rows of data. In-house production processes and testing, as well as other manufacturers and customers created data flows that overwhelmed previous processes and information systems. Spirit’s customer base had grown substantially since their 2005 divestiture from Boeing, resulting in a $41 billion backlog of orders to fill. To address this backlog, meet increased customer demands and minimize additional capital investment, the company needed a way to improve throughput in the existing operational footprint. Spirit had a requirement from customers to increase fuselage production by 30%. To accomplish this goal, Spirit needed real-time information on its value chain and workflow. However, the two terabytes of data being pulled from their SAP ECC was unmanageable and overloaded their business warehouse. It had become time-consuming and difficult to pull aggregate data, disaggregate it for the needed information and then reassemble to create a report. During the 6-8 hours it took to build a report, another work shift (they run three per day) would have already taken place, thus the report content was out-of-date before it was ever delivered. As a result, supervisors often had to rely on manual efforts to provide charts, reports and analysis.
