3D rider model to optimise BMW S 1000 RR aerodynamics

By RIZAL JOHAN | 27 July 2020


MUNICH: The FIM Superbike World Championship (WorldSBK) may have been forced to take a break from racing for a few months, but engineers have been fine-tuning the aerodynamics of the BMW S 1000 RR in the BMW Group Acustic Wind Tunnel.

An important role in this work is being played by BMW Motorrad World SBK Team rider, Eugene Laverty (IRL) – in the form of a 3D model.

Aerodynamics play a key role in determining the top speed of a World Superbike. The goal is to keep the aerodynamic drag as low as possible.

To simulate the flow conditions as realistically as possible, it is not enough to simply position the bike in the wind tunnel by itself. To make this possible, BMW Motorrad Motorsport has turned to an innovative method: 3D scanning.

Detailed measurements means every individual glove finger, every contour of the helmet, every seam in the leather overalls, every crease that affects the aerodynamic drag and with it the airflow.

“Based on the data from the 3D scan, we created a plastic model made of two halves. It took about a week to get all the details right, however our 3D Eugene was then ready for action,” said BMW Motorrad Motorsport Director Marc Bongers.

The BMW Motorrad WorldSBK Team and the real drivers will take place on the first weekend in August. The 2020 WorldSBK season, which was suspended after the opening round in Australia, will resume at Jerez de la Frontera, Spain.
