Are they designing the 787 to flap it's wings so that it doesn't need engines ?

k me, can you imagine the bang if one/both of them let go?

Look at the wing break test video.
Not only does the wing have to attain or exceed the test load, it has to fail within a narrow band of the *predicted* failure load figure. For example, if it broke at double the predicted load, it would still considered to be a design failure until the discrepancy was identified.

I am genuinelty interested in the problems that Boeing have had on this project.
Do you think that they have paid the price for being too adventurous with the use of composites?
I know nothing about this project, what are they trying to achieve with it? are they trying to create a more fuel efficient lighter aircraft by using lightweight composites?I am genuinelty interested in the problems that Boeing have had on this project.

Also interested to hear any problems.

If you asked a senior Boeing project manager your questions, you'd get either a shrug of the shoulders and/or a personal opinion. Whether Boeing have paid the price will not be known for several years or even decades, and even then you'd need to ask an accountant, not an engineer.I am genuinelty interested in the problems that Boeing have had on this project.

Many of the major problems will never be revealed, or even mentioned outside specific design groups within Boeing. Much like many of the problems with the V-22 will never be publically aired. Even a very simple change in one area can have catastrophic and unforseen effects in a completely different system of the aircraft. Changing almost the entire structural material of an aircraft has effects that even the most stringent FMEA process will totally miss. Conversely, some issues are so simple to fix that you'd wonder why they weren't spotted previously.
