传统飞机使用襟翼和方向舵来控制气流，从而控制飞机本身。Aurora 的 X-65 原型机是 DARPA 的“使用新型效应器控制革命性飞机”（CRANE）计划的一部分，它采用主动流控制技术。在原型机上，14 个效应器（飞行表面上的孔）使用加压空气来控制俯仰、滚转和偏航，从而提高性能并降低复杂性。模块化设计允许更换外翼和效应器，使工程师能够测试多种配置而无需建造多架飞机。原型机目前正在建造中，预计 2025 年夏季将首次对全尺寸、7000 磅的飞机进行无人驾驶试飞，速度高达 0.7 马赫。

All the data is then transmitted via Bluetooth to a smartphone app — meaning all you have to supply is some sweat and an epic workout soundtrack.

Keep your look light and crisp with these Laight Jeans from Mott & Bow. And they don't just look good, but they're built for comfort as well, made using high quality 16% stretch denim. And Mott & Bow have a great try-on program which sends you two pairs of jeans with a preprinted prepaid return label to send back the size that does not fit. Available in 32", 34", and now 30" length, they're hand-sanded, stone-washed, and treated for a just-right fade that pairs perfectly with bright spring and summer tops and requires no break-in.
Presented by Mott & Bow.
