Hey guys, I've been having one of my characteristic mental meanders into aircraft design, brought about by an article on the subject.

One thing that it alluded to was fuselage shapes to get better knife edge performance. THere was a comment about having slab sided fuselages work better than rounded ones for a more efficient lfting body, this stands to reason at least in my mind as there would be less spillage of air around the fuselage.

Now this got me thinking about a change to the centre of pressure of the fuselage. I admire Nat Penton's way of getting the CP forward by using more wings to create lift closer to the CG. Now by my way of thinking, would be a reasonable assumption that fuselage depth has grown to the size it has because the fuselage is not efficient in producing lift unless it's of a very large size. Now, if we were to change the shapes of the noses of our aircraft to be more efficient lifters, this would negate the need for a deeper fuselage, which would in turn reduce the shift aft of the CP due to a deep turtledeck?

I guess what I'm saying is, would a more efficient fuselage negate the need for a deep one?
