SmartTruck Aero Systems are the most advanced trailer fuel efficiency solutions available.
SmartTruck’s world-class engineers are recognized leaders in the field of advanced aerodynamic design.
Sophisticated Computational Fluid Dynamics (CFD) and an optimization process using a Genetic Algorithm (GA) allow us to hone the designs of each of our products and components. It’s CFD that allows aircraft designers to not only know that their new aircraft design will actually fly, but how it will perform. With CFD, we don’t just think our products will revolutionize trucking…we know.
|AERO SYSTEM||FUEL SAVINGS|
|Premier Aero System/UT6+||10%|
|Advanced Aero System/UT6||8%|
|Classic Aero System/UT1||5%|
|TopKit Aero System||5%|
Before releasing any product for sale, SmartTruck utilizes various types of advanced testing to determine the factual fuel savings of our products.
Coast Down Testing
Coast Down Testing is currently accepted in EPA’s Heavy Duty Vehicle Fuel Efficiency regulation. EPA points to coast down testing as the Reference Method for determining the aerodynamic performance of a vehicle. Coast down testing allows for the specific determination of a vehicle’s aerodynamic and mechanical (rolling resistance/friction drag) drag.
All SmartTruck products have been performance-validated through coast down testing at either Michelin’s Laurens Proving Grounds in Mountville, SC, or at the Kennedy Space Center at the Shuttle Landing Facility. This coast down testing is used to validate the results achieved in our predictive CFD modeling.
At high speeds, coast down testing helps evaluate the effectiveness of our aerodynamics. At low speeds, coast down testing reflects the amount of frictional rolling resistance and mechanical drag that is present. Testing at the Kennedy Space Center’s Shuttle Landing Facility, with its 15,000 ft. runway, has allowed us to perform unparalleled coast down testing from high speed to full coast stop with a fully weighted Class 8 vehicle. See coast down testing documentation.
SAE J1321 Testing
SAE J1321 Testing is currently accepted by EPA’s SmartWay program. Products listed on EPA’s Verified Technology List can be tested using SAE J1321, with additional testing parameters defined by EPA to ensure better control of testing variability.
All SmartTruck SAE J1321 testing has been completed under the management of KTM Solutions Inc., an engineering services firm that specializes in the automotive and aerospace industries. KTM ensures and attests that all elements of SmartTruck’s testing are done in full accordance with all required J1321 and EPA SmartWay protocols. See SAE J1321 testing documentation.
(For additional information on SmartTruck’s SAE J1321 Testing, see the document entitled, “Summary of SmartTruck System’s SAE J1321 Testing to Date”, available upon request from your SmartTruck representative.)
Third Party Validation
SmartTruck has utilized the expertise of both CD-Adapco and University of Tennessee at Chattanooga SIMCENTER to verify the stated CFD performance of several of its products. In early 2015, SmartTruck’s TopKit Fairing System, a 2015 HDT Top 20 product, was our most recent offering that was performance-validated by the SIMCENTER.
