Teambuilding Teambuilding is an essential part when working in a team as large as the DUT Racing team: “First you build a team, next you build a car�. A team weekend, go-kart outings, enjoying breakfast, lunch and dinner together are all nice examples of teambuilding. Of course celebrating Sinterklaas cannot be forgotten.

During the team weekend the whole team went paintballing. On this photo everyone is still nice to each other, but during the game it proved to be a fierce battle.

The first go-kart outing, the competitive nature of the team was noticeable from the start. This was also the first step in the driver selection process.

Bacon and eggs for the engineers who worked through the night

Producing Lathing, lathing and then some more lathing Since mid-February, there is a special period underway at the team. The period during which all the great ideas that we have worked out in the design phaseare finally being realized. The ordered products arrive one by one and slowly the dream that once only existed in the computer, becomes reality! I’m talking about the production and assembly phase.

On the production side, we have made a lot of parts ourselves. Of course there are parts that we have not created, but these are mostly the parts that are impossible for us to make ourselves because we do not have the proper machines. It is really amazing how much is possible with conventional lathing and milling machines. The main advantage of producing them ourselves is that we gain a good understanding in designing good manufacturable parts. You also get a great appreciation for the people who are good at lathing and milling, because it all has to be done very precisely. A disadvantage of producing it ourselves is that it is more likely that the part has to be redone. On the other hand, this is also good because you will get a very intimate feeling with the parts of the car, especially when it is made with very high standards. It is really “your� part. A simple and dumb block of metal is transformed into a beautiful part that will be on the coolest car in the world. How sweet is that!

The assembly period of DUT13 is even more fun. All prefabricated parts come together and often it all fits exactly! Sometimes it does not fit immediately and a solution has to be found for this. The assembly period remains challenging and it demands a lot more than simply tightening bolts. You will figure out how important bolts actually are. While designing you never think about how important they are. Especially screws and bolts that are hard to reach, next time you will design it in a different place, instead of unbolting a lot of parts to reach this specific bolt! Oh well, good engineers also need to know how to tighten a bolt properly.

Busy laminating the first layer of carbon fibre for the monocoque. A lot of cutting, fitting and glueing is necessary.

Sponsor visits

DU

Racing

Formula Stude

As a team we have to rely on our sponsors, which means that we go visit them every now and than.

We have visited our German motor sponsor quite some times, but also a lot of other sponsors like Fokker, Jeveka, tbp and many others.

For our engineers this poses an opportunity to see more of these companies and learn more about the corporate world.

They also get a bigger insight in what the possibilities are in the manufacturability of their designs.

This year our D:Dreamhal was visited by the Minister of Economic affairs, Minister Henk Kamp, and State Secretary for the Ministry of Education, Culture and Science, Sander Dekker We got the chance to show what we as students are capable of. As a present for the state secretary and minister we gave them a real DUT-racing tie.

Now the both gentlemen can wear a DUT Racing tie to parliament and make their colleagues jealous.

Roll-out

ent Team Delft

After a year of hard work, finally the moment was there. The newest car of the DUT Racing Team, the ‘‘DUT13’’, was revealed previous Friday, June 14 2013, during the annual roll-out event in Delft.

The day started at 12:45 in theater De Veste. All invited guests were received in the big foyer of the theater. While enjoying some music, a drink and some of the old DUT Racing cars, everybody entered the theater during the reception.

The non-Dutch guests were given a headset for a live translation during the presentation. After everyone had entered, the doors of the 500 seats counting theater were opened, everyone took their seats and the presentation started.

Under the guidance of lots of footage from throughout the year Marius Knol, team manager of the team, together with Vincent de Gelder, Technical- and Finance Manager, showed how the year had been and what phases the team went through. Also, the most remarkable lows and highlights of the year passed by.

After that, Frans-Willem Goudsmit from our sponsor VDL ETG told the audience about how their relationship with our team started off and why they chose to support our team. Also Pieter Jan Hagenaars from our sponsor TBP told us about how they experience their new relationship with the DUT Racing team and what kind of integration takes place between the experts from TBP and the students of DUT Racing. Also, he announced that TBP only wants to get more integrated with the team and that TBP is greatly looking forward to the cooperation in the years to come with our team.

At the end of the presentation, the ‘godfather’ of the D:DREAM Hall (the hall DUT Racing is established in), Wim Thijs from the TU Delft, held a very enthusiastic talk about our student team. Also, he put the whole team on the podium for a nice and interactive end of the presentation.

the club, the show only just had to begin. After having built up the tension more than enough, finally the ‘‘DUT13’’, as the new car is named, was revealed. After a grand applause there followed some interesting talks about the car from (among others) Dirk-Jan van der Berg, chairman CvB TU Delft, and Theun Baller, dean of the faculty 3mE. In the end a nice show was given away with the car of two years ago, the ‘‘DUT11’’. After the team picture, everybody took off to our office (also known as ‘t Hok) for a lovely BBQ in the sun.

To conclude, the day was a big success and we would like to thank everyone for their presence. Two weeks from now, we will be pulling everything out of the DUT13 at the first competition of this racing season, at the Silverstone F1 circuit in the United Kingdom. The only thing left now for the team is to go to the United Kingdom Student competitions in England, Germany When at 15:00 everybody walked and Austria and win! from the theater to de Markt, -Max de Feber and lots of people who were not present at the theater yet joined

FS UNITED KINGDOM THURSDAY, JULY 4, 2013, ISSUE 2 WWW.DUTRACING.NL

Silverstone In just over two weeks we get started, the Formula Student season starts in Silverstone the United Kingdom. This is what we lived up to all year, for the first time ever we will see how our design, the DUT13, keeps up against our electric rivals, as well as our combustion competitors. We will compete against our electric rivals as well as our combustion competitors, in total over 120 teams and about 3000 other students will be present. The British Formula 1 race is just finished as we arrive

at the historic Silverstone circuit, located at the centre of ‘’Motorsport Valley’’. This name derives from the fact that over half of all Formula 1 teams are located in this area.

In this inspiring environment we will have to perform at our best for the first time, on Thursday and Friday at the static events and on Saturday and Sunday at the dynamic events. It is going to be a pretty heavy week, since a lot of our engineers are still busy with their exams when FSUK starts on July 3rd, but during the weekend we can rely on over 30 team members at the event. Before it all goes off

in Silverstone it is going to be a very busy period for us, testing the DUT13 and preparing for FSUK. Traditionaly our service truck will go with us on the events, carrying lathing and milling machines, to help ourselves but also to help other teams. We have won this event once before and last year we came in second on just 2.5 points from the Swedish Chalmers university combustion team. Stay tuned to follow us during this event to find out how we performed.
