获得恰到好处的扭矩可以为航空航天公司节省数百万美元

GE Aviation 每年因发动机组装和大修过程中关键点的错误而损失数百万美元。成本体现在生产力损失、测试延迟、客户交付延迟以及排除故障和纠正故障所需的工时。如果直到将发动机发送给客户后才检测到错误，维修成本将成倍增加。

B 型螺母就是这样的关键制造点之一。它们在飞机发动机流体管路和软管中发挥着关键作用，提供坚固、可靠的密封——但前提是正确拧紧和拧紧。如果没有正确拧紧，则需要重新进行维护、取消飞行，甚至在飞行中停机。

GE Aviation 启动了一项结合了三种技术的 AR 部署：Upskill 的 Skylight、Glass Enterprise Edition 智能眼镜和支持 Wi-Fi 的 Atlas-Copco Saltus MWR-85TA 扭矩扳手。

使用 Skylight on Glass，机械师在执行不同的维护任务时直接在他们的视线内接收分步指导说明和图像。当机械师通过标准程序并到达需要应用扭矩扳手的步骤时，Skylight 通过智能眼镜提醒他们，然后在机械师继续之前实时验证正确的值。

• [Efficiency Improvement - Productivity]
  With Skylight, instructions are now provided via the smart glasses. So are guided videos, animations, and images―all configured and accessible at any time for the worker. No stopping, no walking up and down ladders, less risk of injury. Workers can even turn on their camera and call engineers or other support team members for "see what I see" assistance with difficult steps.
• [Efficiency Improvement - Quality Assurance]
  As each nut is finished, Skylight automatically records the final correct torque value. For further documentation, Skylight prompts the mechanic to take a photo of each installed B-nut for historical quality purposes before proceeding to the next step in the procedure.

• On average, across all mechanics studied, the efficiency improvements were between 8 - 11%.

   

• 60% of the participants indicated that they preferred using the wearable technology to the traditional methods.

• 85% of the mechanics agreed to the statements, “I believe that using this system will reduce manufacturing errors,” and, “I thought the system was easy to use.”
