Launched August 2020

OGAB® Advanced TRS®

Utilising patented Active Flow Control technology, Ogab® has developed a breakthrough system that reduces aerodynamic drag force on trains, road and track vehicles guaranteed.

Cutting through the air with our patented invisible air splitter.

By harnessing the power of Active Aerodynamics we can significantly reduce the effect of drag force.

A breakthrough innovation in drag reduction technology to increase performance, cut fuel consumption and significantly reduce harmful CO2 emissions.

We understand the effects of drag force
to get the most from your vehicle.

Where, Fdrag is drag force, ρ is air density, V is vehicle velocity, A is vehicle frontal area and Cdrag is drag coefficient. As evident from this equation, drag force is directly proportional to the air density and vehicle normal area. Therefore, decreasing these two parameters will reduce the drag force. In conventional active or passive drag reduction methods, these two parameters are considered as constant terms and often designers have no control on them.

On the contrary, our proposed technology manipulates the flow field surrounding the vehicle so that these two parameters (i.e. density and frontal area) become dynamic terms and in favour of drag force reduction.

This goal of Advanced TRS® is achieved  by injecting high temperature and high velocity air in the front region of vehicle. By injecting high velocity air the incoming air split into two streams leading to lower area of impact (frontal area) and hence reduce this value in the above equation.

On the other hand by injecting hot air in the front region, low density air surrounds the vehicle body and results in less frictional resistance and hence lower drag force. Since, drag coefficient is directly proportional to drag force, any reduction in drag force will yield to lower drag coefficient.

Distribution of Power Consumption at Various Speeds

When calculating drag force, speed is clearly an important part of the equation. At stop-and-go speeds, drag isn’t a big deal, but the faster you go, the more it matters. At 70 mph, you’ve got four times the force working against your vehicle than you have at 35 mph.

The table below indicates the percentage ratios of the key factors that impact a vehicles power consumption at given speeds. These are attributed to two specific  consumptive causes which are; aerodynamic losses (drag force) and direct power demand from the engine to propel the vehicle forward (rolling and accessories).

As you can see, at speeds of 60 mph and above less than 40% of power consumption is attributed to propelling the vehicle, meaning drag force plays a hugely significant role in the amount of power the vehicle consumes to maintain that speed (62% at 60 mph). Furthermore, at 70 mph, 70% of power consumption is attributed to aerodynamic losses with just 30% attributed to rolling and accessories.

We Can Reduce Drag Force Of Any Train, Road or Track Vehicle By 10% Guaranteed.

The Advanced TRS® delivers benefits such as:

Significant drag reduction

Considerable reduction in fuel consumption

Large reductions in CO2 emissions

Simple and cost effective

Easy to install and maintain

No external design changes to the vehicle

A positive return on investment.

Most importantly of all, we achieve these benefits all while being powered by energy that would otherwise be lost.

How We Recover And Harness Energy That Would Otherwise Be Lost.

Ogab®’s patented solution for recovering energy that would otherwise be lost centres around our state-of-the-art Motor Generator Unit – Pelton (MGU-P). Situated within the turbocharger, the MGU-P has a unique Pelton wheel design that works to generate superior levels of torque that can then create exceptional levels of power. The MGU-P makes it possible to harness this captured energy to power vehicle functions. Consequently, our patented solution can sustainably reduce energy consumption while maximising vehicle performance.
