Velocity Distribution, near exhaust at Mach 1
The vehicle must have a smooth transition,
specially near the exhaust and over the wheels.
The fringe lines, radiating from the surface
shows velocity (therefore local pressure)
variation which must be minimized to lower drag
lift.

Pressure Distribution at the tip at Mach 1
The goal is to reduce pressure variation over the
entire length of the body during the run.
Pressure at the tip (above) varies from 11-22 Psi
