Land Rover BAR prepare to unveil America’s Cup boat

As Ben Ainslie and the Land Rover BAR team head to Fukuoka in Japan for the final event, work continues on Britain’s latest America’s Cup race boat, currently known by the code name R1.

Land Rover BAR are top of the overall America’s Cup World Series leaderboard and this final event on 19-20 November is crucial in determining their position going into Bermuda next summer.

Land Rover BAR is preparing to unveil Britain’s latest America’s Cup racing boat, which uses industry-first aerodynamic testing by Land Rover engineers to exploit and explore new areas of performance gains to make the boat faster through water and the air.

The teams are not allowed to launch their America’s Cup race boats until the end of 2016 and Land Rover BAR will launch R1 early next year in Bermuda, the host venue for the 35th America’s Cup in May and June 2017.

R1 uses industry-first aerodynamic testing by Land Rover engineers to exploit and explore new areas of performance gains to make the boat faster through water and the air.

Land Rover’s engineers have worked on the boat’s giant 77ft high wingsail using sophisticated software to explore the detailed and dynamic performance of the wingsail.

They have analysed 80 million computational cells in each test, which will seek definitive results to help further performance gains.

This software, called Fluid Structure Interaction (FSI), combines aerodynamic testing approaches to increase the performance of the boat’s wing – the catamaran’s main source of power – with structural analysis of its deformation.

This has been created because the carbon fibre wing not only needs to withstand strong winds and be crafted from the lightest structures, but also needs to deform to generate acceleration and speed – not drag.

The FSI system processes data from separate software used to analyse the structure of the wing and the airflow around it. Combining this information is key.

One example is how the Clysar – the film covering the wing – distorts and impacts the boat’s speed due to natural forces.

By combining these processes, the team is able to gain a deeper understanding of the interaction between the wing’s aerodynamics and structural dynamics to evaluate the new airflow and changes to the wing shape.

Richard Hopkirk, Engineering Manager at Land Rover BAR, said:

“We expect to see real gains out on the water next summer as a result of this work. With the America’s Cup, we could have the best sailors in the world, but it’s just as much about the design of the final boat which will give us the cutting edge next summer.”

America’s Cup World Series event, the overall leaderboard is:

1st · Land Rover BAR - 437 pts

2nd · ORACLE TEAM USA - 423 pts

3rd · Emirates Team New Zealand - 420 pts

4th · SoftBank Team Japan - 399 pts

5th · Artemis Racing - 391 pts

6th · Groupama Team France – 360 pts
