Abstract
This paper reports on recent Computational
Fluid Dynamics (CFD) work, revisiting the concept of the
tear drop shaped laminar flow hull and compares it with
practical drag data, both laminar body and torpedo
shape, that has been accumulated over the years. A short
vehicle of length /diameter ratio 3 to 4 can be a more
practical proposition with little if any increase in drag
coefficient (Cd. The laminar flow body, an idea largely
discarded in the 1990s due to practical build difficulties
and shortfall in expected performance, may still have a
lower Cd if care is taken with the placement of external
ancillaries.
