History

Twenty years ago our Chief Scientist, Charles Dixon, embraced the challenge of realizing the powerful potential inherent in the aerodynamics of vortex flow. All aircraft produce vortices in flight: at the wing tips, the aft fuselage and at the wing to fuselage interface. If these vortices can be controlled and manipulated then aircraft performance can be improved. Most engineers have stayed away from this phenomenon because the physics are not well understood, and the mathematics involve formulas and algorithms that either have no solution or require far too much computer computational capacity to arrive at an answer in a reasonable amount of time. The physics of vortex flow are governed by the Navier-Stokes equations of turbulent flow — and to illustrate how difficult this problem is, the Clay Mathematics Institute in Cambridge, Massachusetts (CMI) has established a million dollar prize to anyone who can solve these equations for turbulent vortex flow.

Although there is no known mathematical solution that can be quickly and easily applied, VCT has approached the problem through a combination of analytical and empirical methods involving wind tunnel and flight test data. This approach has produced unique, proprietary, proven technologies that have resulted in software copyrights and patents for concepts that have been flight test proven on multiple aircraft types. Also, these concepts have been successfully demonstrated using computational fluid dynamics.
