With the boat Linnea, built with a balsa wood core with flax and a cashew nut-based epoxy, the team won the entire competition in Palermo, Sicily.</b></p><div dir="ltr"><div dir="ltr"><p style="text-align:left">​Since August last year, masters students from the Naval Architecture and Ocean Engineering program have not only designed and built the sailing dinghy Linnea, but also made all the analyses and calculations that underlie the boat. The Chalmers Formula Sailing team has built the boat of 70 % organic material, and at the end of September, the students went to Palermo, Sicily to participate in the sailing competition. Their participation was possible thanks to funding from the Chalmers University of Technology Foundation.</p> <p style="text-align:left">Besides the team from Chalmers, the competition consisted of student teams from seven Italian universities and one German, all of which have built boats with the same restrictions regarding material. During six races, two elite level sailors in the Olympic 49er class, Fritiof Hedström and Otto Hamel, who are students at Chalmers, sailed the unique boat. </p></div></div> <p>“It is an extreme boat”, says Lars Larsson, Professor of Marine Technology and supervisor of Chalmers Formula Sailing. “It has a large sail plan for its size, and most people who would try to sail it would capsize immediately. The boat would probably overturn from just lying unmanned in the water.”</p> <p></p> <h4 class="chalmersElement-H4">Dramatic competition</h4> <p></p> <p>The Chalmers Formula Sailing team managed to hold top positions throughout the competition. One of the races suddenly became quite dramatic when the boat’s tiller broke. Lars explains that it did not withstand a hit from above and that it was due to a construction flaw. </p> <p>“To sail without a tiller is virtually impossible, but Fritiof laid down across the aft and steered the rudder – which is very heavy and hard to turn – using only his hands. The sailors still managed to score third in the race. You could really tell that they are elite sailors!”</p> <p>Fortunately, the team managed to fix the tiller over the night, just in time for the next race and all in all they won the entire competition. Adam Persson, PhD student, has been the group's supervisor throughout the project, from creating the design to completing the boat. He explains how they won first place.</p> <p>“The boat is built to be as adapted as possible to the wind conditions where we were going to sail. Together with talented sailors, we were faster than the other teams.” </p> <p></p> <p></p> <p></p> <h4 class="chalmersElement-H4">The team is looking forward</h4> <div>The win, he says, was celebrated traditionally by throwing the crew in the pool. Adam continues to say that the competition feels very successful and that the point of a contest like this is getting to compare with other universities and to continuously raise the bar.</div> <p></p> <p>“The win is really a testament to the hard work we put into this project. It shows that with an engineering approach you can make a very good boat. We are of course very pleased with the sailing and we can’t wait for next year’s competition.”</p> <p><br /></p> <p>Read more: <a href="/en/news/Pages/Organic-boat-building.aspx">&quot;Organic boat building in a nutshell&quot;</a>. </p> <p>Learn more about the <a href="/en/centres/sportstechnology/research/sports/sailing/Pages/Formula-Sailing.aspx">project Chalmers Formula Sailing</a>.</p> <p>Learn more about Chalmers investment in sports technology, <a href="/en/centres/sportstechnology/Pages/default.aspx">Chalmers Sports &amp; Technology</a>.<br /></p> <p><br /></p> <p><strong>Text:</strong> Sophia Kristensson<br /></p>Tue, 25 Sep 2018 14:00:00 +0200https://www.chalmers.se/en/news/Pages/Organic-boat-building.aspxhttps://www.chalmers.se/en/news/Pages/Organic-boat-building.aspxOrganic boat building in a nutshell<p><b>​A dinghy with a core made of balsa wood, flax and a cashew nut based epoxy. That’s what eight students at Chalmers are working with this winter. Formula Sailing is a boat building project where 70 percent of the boat core has to be made of biomaterials. In September they will compete in Italy – and during ‘Båtmässan’ they will display the dinghy.</b></p><p>​Since August last year, the students have been designing and building the unusual race dinghy. All the boat builders are all students at the master’s programme Naval Architecture, after studying mechanical engineering their first three years at Chalmers.In an on-campus workshop, the students are laminating the balsa wood boat core with flax and cashew nut based epoxy. Erik Ericsson, one of the students in the project, has been in charge of choosing materials.<br />– We have chosen a core that is a softer and weaker material, balsa wood. And on each side of that core you have a laminate with several layers of flax/bioepoxy. That provides structure with stiffness and strength, says Eriksson. <br />– Epoxy is basically a form a glue that glues together the flax fibers with the core, says Simon Granli who’s also a part of the project group. <br />Eric Eriksson admits the chosen lamination won’t be as good as carbon fiber or glass fiber would be – but those are materials the rules of the competition won’t allow them to use. Based on the flax/cashew nut epoxy’s stiffness to its weight ratio, it’s one of the best possible choices from the organic world. <br />– The weight is important! The less the dinghy weighs, the faster is goes, says Granli. </p> <p><br /></p> <p><strong>Competing in Italy this fall</strong><br />Each year, boats representing universities all over the world compete in a three-day race. Last year, the competition was held in Palermo in September. The two main supervisors at Chalmers then attended the races to see and learn. Most likely the venue will be the same in 2018 and the time will again be late September. <br />During the summer, the Chalmers students will practice sailing the dinghy, and prepare for the competition. The rules state that the sailor of the boat must be a student from the same university as the design and building team, and the recruitment of this person who will be sailing is under way at the time of writing.<br /><br /><strong>Exhibition at Båtmässan</strong></p> <p>From the 3rd to 11th of February, Chalmers Formula Sailing will be exhibiting the sail dinghy at the boat fair, Båtmässan, at Svenska Mässan in Gothenburg, in booth number F04:21 (GKSS).</p> <p><br />See the <a href="https://www.youtube.com/watch?v=XZWEhMJZuNU">video</a></p> <p>Read more about the <a href="/en/centres/sportstechnology/research/sports/sailing/Pages/Formula-Sailing.aspx">Chalmers Formula Sailing project</a></p> <p><span id="ms-rterangepaste-end" style="display:inline-block"><br /></span></p> <strong>FACTS ABOUT THE COMPETITION:</strong><br />Conceive, Design, Implement and Operate are the keywords of the innovative so called CDIO initiative, where the student competition Formula Sailing is included.

By using a carbon fibre  composite with added graphene, the hull is made stronger and lighter. Hydrofoils are added to lift the boat, decreasing drag and allowing greater speeds. After tests performed in SSPAs towing tank, the dinghy was ready to be tried out at sea for the first time.</b></p>​A relatively new occurrence within the sailing world is to mount hydrofoils on small sailing dinghies. Chalmers and SSPA wanted the challenge to do this on “the world´s least advanced sailboat” – the optimist dinghy. The main question and problem for the students and the researchers of this project has been: can an optimist foil and how will this be done? <br /> <br />The optimist dinghy has, since it was conceived in 1947, become one of the world’s most popular sailing dinghies, with over 150 000 boats registered. The boat, only 2.3 metres in length and with a sail area of 3.3 square metres, is normally limited to speeds below 4 knots. <br /> <br />However, by building the boat in carbon fibre and graphene, and fitting it with hydrofoils lifting the hull out of the water, the hydrodynamic resistance can be reduced dramatically. <br /> <br />The hydrofoils, constructed and tested at SSPA, allowed the optimist dinghy to sail as fast as the wind in the recently conducted sea trials, achieving a maximum boat speed of 12 knots in only 12 knots of wind.<br /><br />Watch a video about <a href="https://www.youtube.com/watch?v=UokOO60dsMU">the premiere of the foiling optimist</a><br /><br /><strong>For more information, please contact:</strong><br />Christian Finnsgård, +46- 31 772 9156, mobile +46-730729156, <a href="mailto:christian.finnsgard@chalmers.se">christian.finnsgard@chalmers.se</a>Fri, 07 Apr 2017 00:00:00 +0200https://www.chalmers.se/en/departments/physics/news/Pages/-Police-horses-contribute-to-research-in-physics.aspxhttps://www.chalmers.se/en/departments/physics/news/Pages/-Police-horses-contribute-to-research-in-physics.aspxPolice horses contribute to research in physics<p><b>Recently, fifteen police horses in Gothenburg have contributed to science. They have supported the development of a new method to detect damages in the hooves by using thermoelectric sensors. In the future, hopefully, this technique can be an attractive alternative to other diagnostic tools, for example X-rays.</b></p><div>​“Some injuries in the hoof capsule of the horses can be difficult to detect, for example cracks or infections in the tissue between the hoof wall and the hoof bone. By measuring the heat transport in the hoof it might be possible to detect damages that cannot be observed in other ways”, says Jennie Sköld, Master's student of science engineering physics at Chalmers.<br /><img class="chalmersPosition-FloatRight" alt="sensorer_satts_pa_hasten_170x270_IMG_0038.jpg" src="/en/departments/physics/news/Documents/sensorer_satts_pa_hasten_170x270_IMG_0038.jpg" style="margin:5px" />In this research project she combines two of her major interests: physics and horses. She temporarily moved from Värmland to Gothenburg to fulfill this dream. Together with team members from Chalmers Sports and Technology, University of <span>Gothenburg <span style="display:inline-block"></span></span>and different collaborators from the industry she is making the first studies on live horses.</div> <div>“It’s nice to be part of such a diverse team with unique competence. My experience with horses has really helped me a lot – it’s not necessarily easy to put sensors, wires and equipment on a horse and convince it to stand still”, says Jennie Sköld, scratching today’s collaborator – Viggo – on the back. </div> <div> </div> <div>The horse accepts the procedure, rests his head on the shoulder of his friend and farrier, Björn Berg, and enjoys the candy that he gets from Åsa Hinton, the project’s veterinary. </div> <div> “This is totally harmless for the horse. If this method works out the way we hope it will, hopefully we can detect a stress reaction in the hoof capsule before the problem gets too severe. In some cases, i<span><img class="chalmersPosition-FloatLeft" alt="Jennie_Björn_Åsa_Vigo_270x170_IMG_0045.jpg" src="/en/departments/physics/news/Documents/Jennie_Björn_Åsa_Vigo_270x170_IMG_0045.jpg" height="187" width="298" style="margin:5px" /></span>t might be possible to decrease the area of surgery, since we could know the extent of the defected area”, says Åsa Hinton.  </div> <div>The <span>thermoelectric <span style="display:inline-block"></span></span>sensors attached to the hooves measure the thermal conductivity and makes it possible to see the structure of a healthy hoof capsule. The sensors are developed by a spin-off company from Chalmers – Hot Disk <span> – </span>and the application for horses is brand new. To develop it and make it more user friendly they are working on a prototype that can <span>easily <span style="display:inline-block"></span></span>be put on the hoof.</div> <div> </div> <div>After more than 40 hours in close cooperation with the horses, Jennie Sköld and her supervisor Besira Mekonnen Mihiretie, start to see patterns of how a signal from a healthy hoof capsule looks.
