OTEC PRÄZISIONSFINISH PUTS AIRBUS-TEAM TED IN POLE POSITION26-02-2021
The Shell Eco-marathon is one of the biggest energy efficiency competitions in the world. The challenge is to design a vehicle that can travel further than any other on just one litre of fuel. Drivetrain friction plays a huge part in this.
AIRBUS’s team TED (Technologies et Energies de Demain) has the advantage of OTEC Präzisionsfinish know-how: targeted surface processing technology that produces a marked improvement in the tribological properties of drive components.
THE GREEN LIGHT
The collaboration was sparked by the recommendation of a major automotive manufacturer involved in motorsports. The idea got the go-ahead, and OTEC Präzisionsfinish processed a variety of components for the AIRBUS TED team. The challenge: mechanical precision polishing of gear wheels, crankshafts, camshafts and piston rings to guarantee the indispensably highquality levels demanded in racing.
Alongside vehicle weight, aerodynamics and tyres, friction plays a decisive role in the drivetrain. The more precisely each relevant component is polished while preserving its geometry, the better its tribological properties – and the lower the friction. And the lower the friction, the further the vehicle can travel on that one litre of fuel.
Team member Marc Denante, AIRBUS Engine development, explains …
"The surface finishing of piston rings and other parts in OTEC machines demonstrably reduces friction in the engine. This becomes visible through reduced fuel consumption while maintaining the same engine performance. After second place with 2,561 km/l consumption in 2019, the goal is now to become the world champion in 2021!”
