6% Savings Proven with SAE/TMC J1321 Test Results
Independent Third Party
Standardized Test Results
Energotest 2007 SAE J1321 Procedure by FPinnovations Feric
DOE Sponsored SAE/TMC J1321 Procedure at the TRC
Freight Wing used the TRC to conduct industry
standard SAE/TMC J1321 Type II tests on Freight Products in early 2004.
The SAE/TMC J1321 procedure is the trucking industry standard for comparing the fuel consumption of class 8 trucks because it specifically addresses the needs and operating conditions of long-haul fleets. After conducting these tests the TRC concluded Freight Wing's products
produced the following results:
Freight Wing
Belly Fairing™: 3.87% Efficiency Improvement
Freight Wing Aerodynamic System™: 5.99% Efficiency Improvement
Freight Wing products
represent the most thoroughly evaluated aerodynamic trailer fairings
available to the trucking industry. Seven scientific testing projects have been conducted by respected third
parties including the U.S Department of Energy, EPA Smartway program and
Transport Canada. We openly publish the resulting test reports, because we care about providing accurate fuel savings data. There are many companies that boast fuel savings, but few that back up their claims with standardized tests conducted by impartial and respected professionals.
EPA SmartWay SAE Test at Aberdeen Proving Grounds
In March 2006, Freight Wing
participated in a full scale wind tunnel testing project sponsored by the
National Research Counsel (NRC) of Canada that was open to several developers of
aerodynamic technology. The NRC has one of the world’s largest and most
sophisticated wind tunnel facilities based in Ottawa.
Test results showed a
5.9% reduction in wind averaged drag coefficient at 55 mph with the Belly
Fairing. According to the NRC’s method of estimating fuel savings from wind
tunnel data, this result should produce 4.2% fuel savings at 65 mph.
In the second testing project, the EPA hired
the Southwest Research Institute to conduct SAE standardized tests. The
Freight Wing Belly Fairing and Gap fairing demonstrated an 11.5% fuel
savings in combination with single wide tires in a 65 mph drive cycle.
The first of two test conducted by the EPA
SmartWay partnership was at the Aberdeen proving grounds. It featured the
Freight Wing Belly Fairing in combination with our Gap Fairing and a “boat
tail” rear fairing developed by another company. Data indicated that the
aerodynamic trailer produced a 12% fuel economy gain at 65 mph.
In October of 2007, Freight Wing
participated in the Energotest 2007 initiated by Robert Transport and
Cascades Transport to evaluate energy-efficient technologies. FPinnovations
Feric oversaw this project that was held at Transport Canada's Motor Vehicle
Test Center operated by PMG technologies. Our aerodynamic trailer skirt,
with a wheel cover extension, demonstrated a 7.2% improvement in fuel
economy making it the most efficient trailer skirt tested in this test.

Computational
Fluid Dynamics (CFD) testing was completed on several Freight Wing™ designs by
the consulting division of Fluent Inc., the
world’s leading developer of CFD software. Used extensively by the aerospace and
automotive industries, CFD can accurately estimate the aerodynamic drag on
complex vehicles.
 Tests helped to refine the aerodynamic profile of Freight
Wing™ designs to create the most fuel efficient geometry possible without
sacrificing functionality. The CFD image below uses different colors to indicate
the wind pressure acting on a sample test truck, sporting one of our early rear
fairing concepts.
Several full scale prototypes were built
following the CFD research for road testing with the help of leading industry
OEM's. “Tuft” Strings attached to the fairings were used to visualize airflow
and further streamline their geometry. Prototype tests also evaluated several
different structural designs to maximize durability and operational
effectiveness.
Freight Wing™ fully understands
that if a fairing will not stand up to the punishment of the road, the fuel
savings are meaningless. Several partner fleets have road tested the durability
and effectiveness of our products in their operations. Our fairings have
traveled millions of miles and some units are approaching 2 years of hard service. Every detail including design, material selection, fabrication, installation and ongoing maintenance has been evaluated and optimized for long term performance and value.
Fleet tests have also validated, and in many cases exceeded, the SAE/TMC J1321 test results.
Prove it
for yourself!
Ask us about special trial offers designed to give fleets the opportunity to
evaluate our products. Nothing beats seeing something with your own eyes. Not
only will you be able to demonstrate the fuel savings, but an experienced driver
will immediately feel the improved aerodynamics.
