EXPERT Re-entry Vehicle Thermal FE Analysis - Courtesy Dutch Space

You may have read my earlier post about the End of a Space Shuttle Era – the Space Shuttle’s last flight, where I hinted at what NASA was going to do next. I thought I’d update you a little, sharing work from other companies using SIMULIA’s simulation tools on projects that could decide the future of space travel.

Most recently in the SIMULIA magazine – Realistic Simulation News, Dutch Space shared with us how they used Abaqus to analyze the new re-useable spacecraft test bed (EXPERT) being designed by the European Space Agency. They focused on testing their Thermal Protection System (TPD), which is fitted to the nose-cone, the area of the craft that’s subjected to the brunt of the heat during re-entry.

The nose cone TPS is a very challenging component to design. It has to be structurally strong as well as being able to withstand enormous changes in temperature. Because of this, it’s made up of two parts; a ceramic matrix composite (which handles the extreme heat very well) and a conical metal after body.

Abaqus is able to handle the complex virtual testing of this component, testing temperatures and forces that are very difficult to replicate here on earth

Inflatable Lunar Habitat - Coutesy ILC Dover

One of our other customer’s ILC Dover also shared their story. With the prospect of traveling further than the orbit of our planet always an option, ILC Dover is looking to help support our (relatively) fragile human life forms on other planets. They started back in the 50’s and 60’s by designing space suits for the Apollo missions, but have taken things one step further with inflatable habitats.

I guess you could consider this to be a really big space suit capable of looking after multiple humans, but the inflatable habitat is designed to be a home away from home for traveling astronauts. In this example, the inflatable house is pictured in a lunar environment, using Abaqus, however, has enabled them to test the environmental conditions and the inflation process of the structure in multiple scenarios for any atmospheric condition imaginable.

The habitat is designed to fold down into the smallest space possible for transportation and then inflate to become several times the folded size.

IRL (In Real Life ;-) Sailing with Michel Desjoyeaux!

When we welcomed Michel Desjoyeaux and his team in the Passion for Innovation Program, we had two challenges. The first one was to help Michel to design a new 60 feet monohull for La Route du Rhum-La Banque Postale and the Barcelona World Race in record time. Michel’s team succeeded with the help of our solutions and our experts.

The second one was to produce a 3D experience because Michel was willing to share his life on board with the general public. We produced a 3D visit of the virtual boat and a serious game with an online contest. You can read more about it here.

The time had come for our two winners, Quentin and Thomas, to get on board with Michel Desjoyeaux and his crew. After the virtual experience, they had to taste “the real thing”, and the Dassault Systèmes project team as well.

We enjoyed perfect conditions, with a sunny weather and just enough wind to get fantastic sensations on Michel’s new MOD 70 multi-hull. We also had a chance to sail on the new MACIF monohull, a sister-ship of the FONCIA IMOCA boat and compare the virtual boat we made to reality. Although we found them pretty close,  nothing can replace the wind in the sails and the thrilling sensation of speed when those sea-Formula 1 accelerate!

Our two winners had a chance to steer the MOD 70 and enjoy a private Deluxe Masterclass with Michel Desjoyeaux providing them with advice in person. An unforgettable experience, as you can see in the gallery below. Click on thumbnails to enlarge photos.

Stay tuned for an exclusive Quentin’s interview as well!

Keep 3D-ing,

Rich

 Get to know the winners !

 

Dominik WÖLLM is a german bachelor of arts in industrial design. Dominik finished his studies on HS Pforzheim in 2010

 Presentation of the concept :    Symbion-X is composed of parts of the words symbiosis and bionic.

 A symbiosis is a partnership of convenience between two parties, which complement each other. The term symbiosis is used extensively for any living together. Because the owner is always dependent on the Symbion-X, he builds a symbiosis with him. These facts are reflected clearly in the design. Rims with wires in two parts and casters with adapted elements also build a symbiosis like the seatshell.

Bionic deals with the decoding of „invention of animated nature” and its’ innovative realization of technology. Circular, floral shapes are reflected in the frame and the leaf-shaped seat cushion.

A large part of the seatshell is also a flowing and curved style. As a contrast with it, strongly mechanized parts like wheels, suspension system and forks are visible.

The whole appearance of the Symbion-X is not just like a symbiosis, but it shows concise characteristic of the bionic.

The suspension system and the lightweight seat shell are reducing the degree of intensity affecting the drivers body. This is achieved through a controlled absorbtion of the shock which comes up when the wheels touch the floor. Through this ingenious principle, the burdens of the spine are reduced up to 70%!

The approach from the beginning was to replace the conventional seat and back covering by a shell principle.

The seat is designed to relieve and also stabilize the spine.

The aim was to create a supporting element which achieves a high degree of individuality and functionality while rolling in an upright seating position.

 Dominik used CATIA part design, generative shape design, imagine and shape and different analyzing tools.

The project was created within 3 month from the final sketch to 1:1 scaled model.

It tooks about 1 month for the final design and construction in CATIA.

David BLANC is a french industrial designer, Master GSI Design.

Presentation of the concept :    Elusive is an ideation on modern watches and relativity of time.

Today, watches have other purposes than to give time. They can be linked to jewelry, fashion or technology. In many cases, watches are worn to show social achievement, group belonging or breaking established codes.

David choose to develop the “breaking established codes” theme and create a minimalistic concept watch that shows time differently.

This project attempt to represent the paradox of bringing to life an element that doesn’t exist => Time.

When searching for the correct shape, David came to the conclusion that it would be best to create a watch with a wide-open hole in its center.

It highlights the “notion of time”: a human invention that doesn’t represent anything real or universal.

In addition to this “shape” research, to oppose primary geometric shapes (squares, triangles, hexagons …) with time which is considered ambiguous. To confront the pragmatic side with the creative side. Pragmatism of geometrical shapes shows Man’s will to quantify time.

To emphasize the “unreal” aspect of time, the use of a laser beam has been selected to project directly the hour on the user’s wrist.

The “mechanical clock face” was chosen in order to increase the “Elusive” and “unphysical” aspect of time.

This project was entirely made with CATIA V6.
