Going way way way out on a limb here, but do the crucible fuselage of profile planes benefit from a "chines" like effect?
From wiki:
Chine is also an aerodynamic term referring to the intersection of the upper and lower fuselage surfaces of the Lockheed SR-71 Blackbird which form a 'lip' around the forward fuselage of the aircraft.
The aerodynamicists discovered that the chines generated powerful vortices around themselves, generating much additional lift near the front of the aircraft, leading to surprising improvements in aerodynamic performance.[22] The angle of incidence of the delta wings could then be reduced... Landing speeds were also reduced, since the chines' vortices created turbulent flow over the wings at high angles of attack, making it harder for the wings to stall.
