I have a quick question regarding graduate school. One of my dream's has always been to design aircraft - hence, I would like to focus my career on engineering design. The problem is that I have no idea what type of background a student would need to enter into this type of field. Currently I am going to graduate school for CFD; I understand that some professors research design methodologies, but this seems like a "wishy-washy" subject for a PhD/Masters dissertation. I feel like design is something that you must have a natural ability and can be improved through practice - much like art or music. My question, in short, is what type of background to design engineers typically have before they go into industry? Thanks.
