I am currently working on my PhD in CFD. I need to choose a topic for my thesis. My research area is wing design. I would like to know what possible thesis topics there are related to wing design?

Someone has suggested me to come up with wing design that can handle > 1.3 mach. This design may not be within reach for a few decades, or until quantum computers have become the norm.

Any suggestions would be appreciated.

Thanks

How about wings for micro air vehicles?
