美银称纳指100涨势过度依赖少数AI巨头

2026年10月，NASA介绍在兰利研究中心开展的新型风洞测试，利用压力敏感涂层观察模型机翼周围的气流变化。涂层在特定紫外光照射下发光，亮度随表面压力改变，高速相机记录这些差异后，可生成用于分析和校准计算模型的数据。

试验对象是一种通用超临界机翼模型，作用是为不同研究提供比较基准，并不代表某一款具体飞机。此次测试把非定常压力测量方法用于低氧环境中的大型自由运动模型，扩展了相关技术的适用条件。相比只在少数位置安装传感器，表面发光信息能够帮助观察更连续的压力分布和快速变化。研究人员希望进一步将方法应用于会弯曲、会随气流调整形态的柔性机翼，为提高飞行效率提供实验依据。这里的彩色发光来自测量材料与照明系统，不是机翼本身产生了新的推进能力。测试成果主要改善空气动力学数据获取方式，为未来设计与仿真建立更可靠的对照。
