Thanks , a good point but am I safe to assume that that lift would be LESS than with a "teardrop" shape .... the one we all automatically think in terms of.
Here are few photos of a rough model I made today. The sides are flat and the maximum cross section is around mid way but there is no foil. The rear could be narrowed more or even tapered a little without generating lift.
It is quite similar to the Vetter fairing and would have the same frontal area . Could i have some comments on this idea ?
