VorBlade Trailer Wing™ System is EPA SmartWay Certified and CARB Compliant aerodynamic device meeting the CARB minimum requirement to improve fuel efficiency by over 5% for dry vans and reefers with swing doors or rollup door.
VorBladeTM systems have been thoroughly tested in a wind tunnel and analyzed theoretically and using computational fluid dynamics (CFD). The systems have also undergone real-life road tests on a freeway and independently performed fully controlled track tests.
Wind tunnel tests have shown that lifespan of VorBlade-generated vortices exceeds 10 ft and reduce air drag of bluff bodies by up to 65% at air speed 67 mph. CFD simulations at air speed 67 mph have shown that VorBlade vortex generators on the tractor and trailer ends reduce air drag by 23% at no crosswind and by 31% at 18 mph crosswind. The road tests have been executed in Colorado on interstate I-70 over a circular route of about 114 miles at a speed of about 60 mph and have shown about 3.7% fuel saving by the VorBladeTM Tractor System and about 8.8% by VorBladeTM Tractor & Trailer System.
Controlled tests of the VorBlade Trailer WingTM System with Crosswind MitigatorTM Subsystem were performed by the independent authority, the EPA-authorized Texas A&M Transportation Institute, in accordance with the SAE J1321 testing procedures and the 2011 EPA SmartWay modifications outlined in the EPA-420-F-09-046 document. The testing was conducted at the Pecos Research and Testing Center in Texas on a 9-mile circular track at a speed 64 mph. The tests have shown fuel saving of about 9.5% with the accuracy within ±1%.
