Both the two and three dimensional experiments indicated an object's shape
greatly influences its aerodynamic properties. It was found that lengthening
an object while keeping the silhouette area and frontal shape constant makes
it possible to decrease turbulence. It was also concluded that structures with
round frontal shapes have better aerodynamic properties than pointed structures
which are, in turn, better than flat frontal surfaces. These points were
observed during experimentation in two dimensions and also in three dimensions
when using the hemispheres and cones only. The teardrop data was found to be
inconclusive in this area, perhaps because the margin of error when joining the
cones to the hemispheres was too large to achieve accurate results.
Some theoretical assumptions can be made about the qualitative comparisons
between shapes that could be considered in the construction of a locomotive
entity. A deeper understanding of the shapes of everyday locomotive structures
such as planes and automobiles was achieved. Modern day planes and automobiles
use rounded frontal surfaces for the reasons that were concluded from the two
and three dimensional experiments. Also by elongating the structure the drag
is further reduced as was observed. An example of a modern day automobile that
puts these observations effectively to work would be the Oldsmobile Aurora. A
modern day aircraft that makes use of these results is the USAF's C-130
Hercules.
