One-Way Assembly Sensor-based digital verification -Technology accelerator – Phase 1 (OWAST)

传统的机身装配方法手工强度大、效率低。部件组装在一起并钻孔后，在重新组装并用紧固件连接之前，要进行拆卸、检查和返工。这是由于装配装配、材料和动态，以及质量和速度要求，使孔的生成具有挑战性。该项目将开发一种按比例缩小的试验台，它可以模拟生产装配的动态，以及从过程中的数据推断孔质量的技术。输出将有助于使用过程中数据进行孔洞生成测试和孔洞验证。这将使采用组装工艺而无需中间拆卸，极大地提高飞机组装效率。

Traditional methods of airframe assembly are manually-intensive and inefficient. After components are placed together and drilled, they are disassembled, inspected and reworked before being reassembled and joined with fasteners. This is due to assembly fit-up, materials and dynamics, along with quality and rate requirements, making hole generation challenging. This project will develop a scaled-down test-rig, which can mimic dynamics of production assemblies, and techniques for inferring hole quality from in-process data. Outputs will facilitate hole generation testing and hole verification using in-process data. This will enable adoption of assembly processes without intermediate disassembly, drastically improving aircraft assembly efficiency.
