挑战
美国海军陆战队计划在本世纪末推出新型远征战车（EFV）。这种混合坦克/船设计可在陆地和海上运载 20 名人员，速度高达每小时 30 英里。然而，EFV 包含的环境控制系统 (ECS) 不符合标准。 ECS 本质上是一种高性能空调，即使在室外温度高达 125 华氏度的情况下，也能将机舱空气保持在舒适的温度，同时运行时足够安静，不会对机组人员的听力造成风险。最初的原型未能满足这些标准，导致重新招标。 Fairchild Controls Corporation 赢得了重新投标，并负责改善 ECS 装置的气流并最大限度地降低运行噪音，所有这些都在严格的预算和 14 个月的紧迫期限内完成。
关于客户
此次的客户是美国海军陆战队，它是美国武装部队的一个分支，负责提供力量投射，利用美国海军的机动能力快速运送联合兵种特遣部队。海军陆战队以承担军队最困难和最大胆的任务而闻名，并且严重依赖先进技术在残酷的环境中保护其部队。他们正在推出一款新型远征战车 (EFV)，这是一种混合型坦克/船，旨在以高速在陆地和海上运载 20 名人员。EFV 的装备和装甲更精良，但速度更快，机动性更强，将成为海军陆战队的主要作战车辆。
解决方案
Fairchild Controls 决定用具有旋转元件和固定元件的较慢的混流风扇取代原始型号的快速但噪音较大的叶片轴流风扇。为了设计风扇，该公司使用了 ANSYS, Inc. 的 CFX 软件，这是一款强大的流体动力学建模解决方案。该软件允许工程师创建和分析候选风扇设计的 3D 模型，比较叶片形状、数量和高度的各种组合，并选择满足所有性能目标的设计。该软件还允许团队在各种模拟操作条件下模拟性能并探索假设场景。在接下来的三个月里，Fairchild Controls 构建了一个工作原型，将所选设计的几何形状导入其 CAD 系统，直接从实体对其计算机自动化加工工具进行编码，并组装了工作原型。
