Drag is one of the most consistent problems people have been trying to solve when it comes to semi-trailers. Making engines more and more fuel efficient can hardly make a dent in the industry when air resistance just makes engines work harder to overcome the force. But a lot of drag has been done away with when it comes to the trailers themselves.
There are two main areas for air resistance: under the body of the trailer, and behind the trailer. Both of these areas are covered through paneling. Side panels, or aerodynamic panel skirts, keep air from finding traction on the undercarriage and tires; the panels push air away or just stop it from reaching under the trailer in the first place so it can't push back. The same is true with the, less common, rear tail fairings, which reduce drag at the back of the trailer. Using both can improve fuel efficiency up to fifteen percent, but only if you drive a high-speed, longer route.
Air resistance takes hold wherever it can, and that includes the gap between the back of your truck and the start of your trailer, where air can dip into and push against the flat front. But XStream Trucking created TruckWings in response: a retractable set of paneling that fits into that gap so there is a continuous surface from the front of your truck to the end of the trailer. The panels are smart, so they are programmed to retract once you start to slow for a turn. This can add another 5 percent to your fuel efficiency, especially on long, interstate drives.
Chipping away at percentages helps keep your company's expenses lower and your profit margins higher. Go to County Supply for more technology and industry news.
