About Windyne Fairing Systems
Trailer Aerodynamic Improvements

Since its inception, Windyne has focused on trailer aerodynamic improvements and upgrading the design of trailer side skirts.

Inspired by research performed by NASA in the 1970's, and in response to demand from the trucking industry, Windyne developed the most aerodynamic and convenient trailer fairing system on the market - Windyne Flip and Slide™ trailer side skirts.

Windyne side skirts offer full coverage, full access to the undercarriage, maximum safety, and maximum fuel savings and emission savings.

The Journey
To Innovation

Our journey of trailer aerodynamic improvements - from a zero coverage undercarriage to the Future of Fairings.

The Brick - Zero Coverage, Zero Protection, Zero Fuel Savings

The brick is a ‘naked trailer’ without any fuel saving devices. An open undercarriage creates wind resistance which lowers fuel savings and increases emissions. The underbelly of the trailer has the largest surface area and is a major contributor to the loss of fuel efficiency of long-haul trailers. Wind resistance is created when air enters the underside of the trailer and interacts negatively with equipment, tires, etc. creating drag and increasing fuel consumption and emissions. The more speed a trailer has the more wind resistance that is created.

NASA Studies - 12% Fuel Savings by Increasing Aerodynamics of the Trailer

NASA conducted a series of tests in the 1970's centered around tractor and semi-trailer aerodynamics. These tests concluded that 12% fuel savings could be achieved by enclosing the underside of the trailer to prevent wind, crosswinds, and turbulence from other traffic from entering the underbelly of the trailer and negatively interacting with equipment, tires, etc. While, an important discovery, the challenge facing the industry was how to enclose the undercarriage affordably and still maintain the necessary functionality of the tractor and trailer?

Enclosing the Undercarriage Restricts Access to Important Gear

Enclosing the underside of the trailer for semi-trailer aerodynamics restricts access to important gear in the undercarriage. Partial coverage fixed fairing products emerged as a compromise to allow for improved aerodynamics in certain load positions while not overly restricting access to the undercarriage. Due to the fixed and partial nature of such products, they left a large gap which reduced fuel savings and prevented access to the undercarriage during certain load positions. Windyne embarked on a mission to develop a fairing system without compromises.

The Solution

After countless hours and over 6 million dollars spent on research, design, development and testing Windyne created the most innovative all-in-one fairing system on the market. Windyne Flip and Slide™ flex trailer side skirts provide unmatched fuel savings and emissions reductions in all load positions, unrestricted and convenient access to the undercarriage, side guard protection and numerous other benefits.

Unmatched Performance

Windyne’s patented technology allows the side skirt to vertically retract to a near flush position against the side of the trailer to enable full access to the undercarriage in 30 seconds and easy deep docking. Innovative planning and design enable Flip and Slide™ fairings to adjust automatically (telescope) to compensate for all vehicle load and wheel positions allowing the driver to maintain load balance and make necessary adjustments without additional work or having to worry about adjusting the trailer fairings. Other features of Windyne Flip and Slide™ flex trailer side skirts include maximum coverage, side guard protection, quick access panels for landing gear, a flex skirt for maximum vertical coverage, improved handling and control, reduced wear on tractor and engine, top quality materials for a long lifespan and more. Most Windyne customers achieve at least 1 extra mile per gallon over the long haul.

"If you're in it for the Long Haul then it's time to enjoy some Real Fuel Savings!"

* Disclaimer:
Reported fuel savings of 1 mpg (235 L / 100 km) is a fair average in most long-haul driving situations - based upon real-world freight scenarios where data was meticulously recorded by numerous drivers across various terrains and weather conditions. However, individual fuel savings are dependent upon many factors including, but not limited to, driving habits; bogeys in the forward or rearward positions; long haul versus mid-range versus city driving scenarios; temperature: extreme heat or cold; weather conditions: wind, rain, snow, etc.; types of terrain, grade of slope, and load volume and type. For example, drivers may experience greater fuel savings over longer distances and lesser fuel savings during shorter trips and city driving. Despite these factors, users of Windyne Fairing Systems average 1 mile per gallon in fuel savings - no fixed fairing can outperform Windyne Fairing Systems in the same long-haul situations.
