Verney Yachts Ocean F1: Part 2 (Biz + FSI)

By Tom

Hello Everyone!

One of the things that interest me most about Verney Yachts is the amount of business acumen and collaboration skills that you must have to be able to drive a project forward. It’s impossible to get a project like this down the slipway without collaborating with other people and organisations.

To that end, Verney Yachts are working with Capvidia, a partner of Dassault Systèmes and now Verney Yachts. Tim has used FlowVision CFD coupled with Abaqus to perform a Fluid-Structure Interaction (FSI) simulation.

The FSI analysis simulates the above surface aerodynamics of the boat, and is critical to V39-Albatross’ success.  It establishes overall aerodynamic forces and moments acting on the boat with different control inputs. Multiple analyses are conducted all with different boat velocities. This process helps the Verney team tune the control system to minimise control cross coupling and to maximise forward thrust, whilst maintaining roll balance of the overall boat.

Also part of Dassault Systèmes’ Passion for Innovation programme, the Verney Yachts team is using SolidWorks for the structural 3D design and Abaqus for realistic virtual testing. These tools are critical to the on time, low cost design and build of the boat.

As Tim Clarke, lead engineer and founder of Verney Yachts mentions:

“One of the side effects of building a keel for such high speed sailing is that it becomes very sensitive to twisting under load. We’re using Abaqus to tune the carbon fibre composite keel to minimise twisting across the speed range.”

It’s this perfect example of working collaboratively with multiple partners that drives projects like V39-Albatross on to break world records!  Do you agree?

Tune in next week for more on Verney Yachts. I’ll be looking at the project goals and what breaking a world record for speed sailing actually involves!

Cheers,
Tom

The Power of Under Armour + ENOVIA

By Kate

I never used to think about how companies crank out clothing lines until I started working for Dassault Systèmes. Well, let me take that back. I’d thought about fashion designers with their colored pencils and drawing pads, but that’s about it.

But when you think about it, apparel companies are lean, steaming production machines. Crank takes on new meaning. And you’ve got to do it with the right ‘products’ that meet ever-changing consumer trends.

Now add TECHNICAL WEAR to the mix. I mean intelligent clothes that help your sports performance. We’re not quite ready for mainstream mood altering apparel (it’s in the works, folks, think nanoscience!), but there is a new apparel category called Performance Apparel.  So not only do they have to crank, they have to engineer too!

The common goal between Under Armour’s designers, developers, sourcing people, and all the rest is to “make all athletes better.” Their CIO Jody Giles explains how they accomplish this, “getting that ball over the finish line” in the video below. Crank up your volume if you like rock music!

Another video brought to you by what I lovingly call . . . the DS Cube.

So next time you buy Under Armour, maybe you’ll think about Dassault Systèmes and ENOVIA . . .

Best,

Kate

Verney Yachts – Ocean F1: Part 1

By Tom

The F1 Team of the Ocean

It’s been a while since I last blogged, but I’ve been saving up a good one for you as follow-up to my first Verney Yachts post.   This is the first in a three part mini-series of blogging about Verney Yachts (@V39Albatross), so stay tuned for the next three Tuesdays to find out more!

At the 2010 SCC – Tim Clarke of Verney presented an excellent overview of the preliminary design of the wing-sail for the V-39 Albatross. He mentioned that the Verney team is conducting all of the design and the prototype work virtually using Abaqus and other CAE tools, with no plans to build a physical prototype – “Numerical simulation is the only realistic method to test the boat” It’s the wing-sail that I’ll talk about in today’s post.

This method is a similar one to the F1 team Virgin Racing who designed this year’s car 100 percent using numerical methods, including CFD and FEA.

The wing-sail is a unique device designed to do two things; propel the boat forwards, as well as lifting it out of the water so it flies in ground effect just above the surface. This is similar to an Ekronoplan in concept just without an engine.

A wing-sail is made up of an inner and outer plank. Each plank can rotate about its longitudinal axis into the local air-stream. The amount of lift generated by each plank can be controlled by the pilot. This approach to the control of each wing-sail has massively helped the team keep weight to a minimum – the low weight of the boat is essential to its success.

That’s all for this week, tune in again next week to hear about Verney becoming part of the Dassault Systèmes Passion for Innovation programme, and more on the team as they strive towards the record attempt.

Until next week,

Tom
