Dreamliner Delamination: Aircraft Designers Turn to Simulation to Avert Issues

Friday, March 2, 2012

, Vice President of Aerospace & Composites at Altair

This post is taken from Simulate to Innovate

I recently provided insights on Boeing’s delamination issue to’s Military & Aerospace DesignLine, discussing the challenges experienced when moving to different manufacturing methods and new materials. Here’s a preview of my thoughts on the issue:


The recent delamination issue with the Boeing 787 reported in the news (787 Delamination) highlights the challenges in moving to different manufacturing methods with new materials. There are tremendous advantages to the use of composite materials but there is less experience manufacturing with these materials and these types of problems are bound to occur. As stated by Boeing, there is no safety issue here but it is slowing down the production line.

Check out the rest of my commentary here.

  1. The “ease” of the does seems like very good news but I think it also reflects the work that Boeing and supliper engineers did during the delay to mature the systems and work the bugs and kinks. I think this cannot be underestimated. Boeing had the systems in the systems integration lab testing and retesting them. I think that’s why gauntlet testing went well. Does that mean that the remaining gauntlets will go just as well. Perhaps but the key difference is now all the systems are on one platform with engines and without external power being supplied. When the engines are running and the APU is on do these systems work well together? That’s going to be answered in the upcoming tests.As far as the timing between the first taxi tests and first flight…I think that timing should be pretty quick, 5 days, I don’t know but perhaps a week. The 787 is a little bit more of an unknown quantity compared to the 777F.
