VCT’s patented Finlets significantly reduce aerodynamic drag resulting in reduced aircraft fuel consumption and increased range and endurance. VC Finlets are specially shaped devices that are attached to the aft portion of the aircraft fuselage and reshape the airflow to improve the pressure distribution and reduce flow separation and thereby reduce profile drag. Using the Company’s proprietary software in conjunction with Computational Fluid Dynamics (CFD) , VCT is able to analyze any aircraft type and individually adapt the VC Finlet configuration for maximum performance.
All aircraft produce vortices in flight, particularly at the wing tips, wing to fuselage interface, and aft fuselage
Vortex flow is a significant source of aircraft drag, particularly on aircraft with upswept after bodies such as the C-130, C-17 and B-747
VCT has unique and protected state-of-the-art aerodynamic technology as well as copyright protected software that enables engineers to model, predict, redirect and control aircraft vortex flow
A vortex (plural: vortices) is a spinning, often turbulent, flow of fluid. Any spiral motion with closed streamlines is vortex flow
Additional Benefits of Finlets
• In many cases, increased payload
• Increased time on station (important for military aircraft)
• Reduced Carbon Emissions – Example: 9M lbs. per year for a single Boeing 747 aircraft
• The drag reduction is in addition to other devices, such as winglets, if they are also installed on the aircraft.
• The modification is light weight and has minimum impact to aircraft structure unlike winglets and can be accomplished in day by line maintenance
• The VC Finlets are a totally passive system with no impact to aircraft systems or maintenance costs other than routine corrosion inspection/repair.
