VorBlade systems were developed with the help of CFD computer simulations and extensive wind tunnel tests. On the post-development stage, we’ve preformed VorBlades on highway and open track tests. Tests were in accordance with the 1986 SAE J1321 and the 2011 EPA Modifications to SAE J1321. Road tests resulted in 8.76% average fuel saving (0.86 mpg improvement) by the VorBlade full system (vortex generators were installed on tractor and trailer, but no wing was used) and 3.76% for the Cab System only. The controlled environment track tests resulted in 9.46% fuel savings for the full Wing System.
Texas Transportation Institute performed independent tests. Accuracy of the results was verified by the EPA SmartWay engineering team. More technical information is presented at our “TECH INFO” page.
The VorBlade invisible fairings system shows substantially better performance than any conventional trailer fairings for the following reasons:
It works along the full length of a tractor and trailer
VorBlade creates long lasting smooth air flow behind a vehicle. Similar results could be hypothetically achieved by at least 10ft-long tail fairings, which do not exist
VorBlade system is light (6lbs – 50lbs depending on configuration), durable (made out of specifically adapted plastic alloy), and easy to install
The VorBlade™ system does not interfere with any vehicle operations, or require any maintenance
Due to scientifically designed intake, it fully performs while iced and even operates at 25-30% of its full capacity while plugged with snow or ice
VorBlade™ Systems are the ONLY drag-reducing aerodynamic devices on the market that effectively fight crosswinds VorBlade™ reduces negative cross wind impacts by 60%. One windy day can cost you more than VorBlade™ System. 10 windy days will definitely pay for it
VORBLADE™ OR SKIRTS
Already got skirts? VorBlade systems work in conjunction with skirts. Skirts address the undercarriage drag, which accounts for about 28% of the total aerodynamic drag. Whereas VorBlade™ system helps with 53% of the total air drag, in areas that are not covered by trailer skirts.
Do you really need trailer skirts to be C.A.R.B. compliant? Not necessarily – the skirts are just one of the options.
As stated by C.A.R.B.: “The Tractor Trailer GHG Regulation requires owners of affected 53-foot or longer box-type trailers to install a SmartWay verified aerodynamic technology that has been verified to either the 4% or 5% fuel savings level – 4% for refrigerated-van trailers and 5% for dry-van trailers.” Hence, you can go to the EPA SmartWay website and choose any product verified under “Advanced Trailer End Fairings” or “Advanced Trailer Skirts”. We also recommend to search what every product does and choose accordingly to your needs. For example VorBlade Systems work at lower speeds and provide more benefits than just the minimum required fuel saving of 5%.
VORBLADE™: CLEANER TRUCK, BETTER VISIBILITY AND EASIER ACCELERATION
VorBlade significantly improves visibility around other vehicles and keeps vehicles much cleaner due to 50% suppression of turbulence-related flying particles.
VorBlade helps to increase acceleration power by about 3-4% and to maintain speed, due to the preserved energy that is no longer consumed by air drag.
