Hydrodynamic studies improve F1 fuel flow

A BAE Systems product story

BAE Systems has helped Formula 1 Team McLaren Mercedes prepare for the 2006 Formula 1 season by improving fuel management in its cars via smoothed particle hydrodynamics.

BAE Systems has helped Formula 1 Team McLaren Mercedes prepare for the 2006 Formula 1 season by improving fuel management in its cars via smoothed particle hydrodynamics (SPH) - a technique that can simulate the movement of fluids in containers and pipes, first applied to the management of fuel in aircraft tanks.

As part of its technology partnership with Team McLaren Mercedes - which is celebrating its tenth year in 2006 - the BAE Systems Advanced Technology Centre has supplied computer modelling which enabled a redesign of Team McLaren Mercedes' fuel tanks, leading to more accurate determination of the fuel remaining and improvements to the car's centre of gravity.

These advances have already enhanced track performance as the redesigned fuel tank was used on the Team McLaren Mercedes 2005 car - the MP4-20, the fastest on the grid throughout the season.

Dr Robert Banim, Principal Engineer at the BAE Systems Advanced Technology Centre, said: "We were able to change the way Team McLaren Mercedes measures and visualises fuel slosh".

"The fuel tank redesign based on the simulation results had a direct, positive impact on last year's car".

A similar technique is now being used to assist the design of the gearbox by modelling the movement of oil through the connecting pipes, the gearbox enclosure and the rotating gears.

This test programme started in January 2005 with the results being fed into the design of the 2006 car.

BAE Systems and Team McLaren Mercedes are currently working on technologies with the aim of enhancing performance and McLaren's chance of track success, with recent notable advances in carbon fibre techniques and wireless systems.

BAE Systems aims to take as much from Team McLaren Mercedes as it gives, particularly when it comes to studying the speed of the build and operations processes in Formula 1.

Ron Dennis, Chairman and CEO of McLaren Group said: "By anybody's standards, BAE Systems is a technology power house".

"It provides us with great technology at all levels, whether it be aerodynamics, simulation, mechanical design or IT".

"We share the same commitment to innovation and the pursuit of excellence through leading edge technology and we both have world-class aspirations".

"It is a true partnership in every sense".

Memorable events during the decade long partnership include: Mika Hakkinen and David Coulthard testing their handling skills in a Eurofighter Typhoon flight simulator; Ron Dennis officially opening the BAE Systems led Systems Engineering Innovation Centre (SEIC) at Loughborough University; and a Eurofighter Typhoon racing a Team McLaren Mercedes F1 car.
