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

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

Verney Yachts – Ocean F1: Part 1

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

Frank Gehry Shares CATIA Secret

Eighty-one-year-old Frank Gehry has rightfully earned his label as “the most important architect of our age,” as was voted in the 2010 World Architect Survey.

I had the honor of meeting Gehry in early 2009 and got to ask him questions on his views on the future of architecture and 3D as an innovation tool.

And today I’m proud to share with you another Gehry video, although much prettier and professional than mine, where Gehry talks specifically about how Dassault Systèmes CATIA software is key to his architectural realizations.

Some of my favorite quotes include:

“We’ve got powers that architects don’t usually have.”

And

“You can’t do it without any other software out there.”

So here’s your chance to hear from the master himself some of his secrets . . . and enjoy the beautiful footage.

Many thanks to Elodie and Karin for allowing me to put this video extract onto our YouTube channel.  The Gehry video is part of an online video-cube presentation on the Dassault Systèmes group.  It’s worth a tour, so please check it out when you have a chance.

Meanwhile I’ll get back with you soon with other of my favorite extracts.

And BTW . . . what do you think?

Best,

Kate
