Evidence of comprehensive hazard identification is a crucial component of any aerospace certification argument. Historically, in the early stages of the aerospace safety assessment process, hazard identification has been performed through use of hazard checklists – derived from lists of previously identified or experienced hazards. The arguments used in support of this approach are predominantl...

In this study, an electroactive polymer (EAP), poly(2,5-bis(N-methyl-N-hexylamino)phenylene vinylene) (BAM-PPV) was investigated as a potential alternative surface pretreatment for hexavalent chromium (Cr(VI))-based aerospace coatings. BAM-PPV was tested as a pretreatment coating on an aerospace aluminum alloy (AA2024-T3) substrate in combination with a non-Cr(VI) epoxy primer and a polyurethan...

Modern aerospace systems are marvels of engineering. Their amazing achievements are due in large part to software, yet relatively few project personnel, especially project management staff, understand or appreciate the significance of it. The lack of understanding and attention to software often dooms large aerospace projects to significant delay if not outright failure. As a motivation, severa...

Today’s aerospace assembly is a huge manual task according to strictly controlled instructions, where different operators are responsible for different areas. This harmonizes with the overall lean approach, but the assembly is very time-consuming and some tasks are not ergonomically friendly, such as assembly tasks inside a wing box. Here, it could be possible to increase automation with the ai...
