Evaluating and Developing Flow Motion Technology in Alpine Skiing DEGREE PROJECT IN DESIGN AND PRODUCT REALISATION, SECOND CYCLE, 30 CREDITS STOCKHOLM, SWEDEN 2018 Evaluating and developing Flow Motion Technology in alpine skiing LINN RILEGÅRD KTH ROYAL INSTITUTE OF TECHNOLOGY SCHOOL OF INDUSTRIAL ENGINEERING AND MANAGEMENT 1 Evaluating and developing Flow Motion Technology in alpine skiing Linn Rilegård Master of Science Thesis TRITA-ITM-EX 2018:651 KTH Industrial Engineering and Management Machine Design SE-100 44 STOCKHOLM 2 3 Examensarbete TRITA-ITM-EX 2018:651 Utvärdering och utveckling av Flow Motion Technology för alpinskidor Linn Rilegård Godkänt Examinator Handledare 2018-12-22 Claes Tisell Stefan Björklund Uppdragsgivare Kontaktperson Flow Motion Technology AB Fredrik Andersson Sammanfattning Alpinskidåkning är indelat i ett flertal sportgrenar, så som slalom, storslalom, freeride och störtlopp. Inom aplinskidåkning är tid en viktig faktor. Under tävling kämpar deltagarna såväl mot varandra som mot klockan, varje hundradels sekund räknas. Utrustning och teknologi utvecklas konstant för att ligga i framkant och förbättras för att få skidåkare att nå allt bättre resultat. I det här examensarbetet implementeras en teknik som kallas Flow Motion Technology i skidor för alpin åkning. Produkten utvecklas och utvärderas. Flow Motion Technology AB är ett företag stationerat i Östersund som har utvecklat en teknologi som nu används i ishockey- och skate-produkter. Denna teknologi är patenterad och företaget är intresserade av att undersöka möjliga sportgrenar där denna princip kan implementeras. I detta examensarbete har teknologin implementerats i slalomskidor, testats samt utvecklats. Arbetet ska svara mot följande frågeställning; Finns det tillräckligt med potential och fördelar med implementering av Flow Motion Technology i alpin skidor för att kunna rekommendera företaget att investera i framtida utveckling för detta? Resultatet av examensarbetet var att tester som gjorts krävde mer avancerad utrustning för att fullständigt besvara frågan. Om testerna genomförs med bättre utrustning kan mer korrekta resultat utläsas och utvärderas. Resultatet av projektet blir därför att ingen rekommendation rörande om företaget bör fortsätta investera i en alpin platta med FMT i, kan ges. Om fler tester görs, med bättre utrustning kan korrekt data erhållas och en analys kan göras på en bättre grund. 4 5 Master of Science Thesis TRITA-ITM-EX 2018:651 Evaluating and developing Flow Motion Technology in alpine skiing Linn Rilegård Approved Examiner Supervisor 2018-12-22 Claes Tisell Stefan Björklund Commissioner Contact person Flow Motion Technology AB Fredrik Andersson Abstract Alpine skiing is divided into several sports, such as slalom, freeride, giant slalom and downhill. In all these disciplines, time is an important factor. Competing against each other and against the clock makes every hundred of a second count. Equipment and technology are constantly improved to help the skier reach higher results. In this report a technology called Flow Motion Technology is implemented and evaluated in alpine skis. Flow Motion Technology AB is a company based in Östersund that developed a principle now used in ice hockey and skate products. This technology is patented and the company is interested in examining possible sports branches that this principle can be implemented in. In this Master thesis project, the principle has been implemented in slalom skiing, tested and developed. What the work is about to answer is the question that follows. Are there enough potential and benefits of implementing Flow Motion Technology in slalom skis to be able to recommend the company to invest in future development for this? The result of the degree work was that tests made in the project required more advanced equipment to answer that research question correctly. If tests are performed with better equipment, more accurate data could be received and analyzed. The answer of the research question could therefore not be answered in this report. The recommendation to Flow Motion Technology could not be presented without further tests and analyzes. 6 7 FOREWORD I would like to thank Fredrik Andersson and the rest of the team of Flow Motion Technology, for support and guidance. I would also like to thank Stefan Björklund for supervision during the project and for reviewing the report. During the project, a lot of people helped me with knowledge and guidance. I would like to send a special thanks to Tomas Östberg, for help with manufacturing of prototypes, Malin Åkermo for discussions concerning concepts and carbon fibre and Per Wennhagen for help with tests at KTH.

  • 10 Steps to the Perfect Ski-Boot! (The Process for Snowboard-Boots Is Very Similar)
    10 Steps To The Perfect Ski-Boot! (The Process for Snowboard-Boots is very similar) Step 1: Realize that you are unhappy with your ski boots Only you can judge what you want and what really fits. So: do not listen to others, friends or family – only to your own body”! Good advice from the specialist is here the most important input. Step 2: Segment the type of skier you are How well do you ski? What kind of pistes and where do you ski mainly? What is your style and hence to what should the ski-boot enable you to do? What ski-boot did you have so far – what was good/not so good about it? What was the flex index? Step 3: Measure the feet, legs and body axis Exact picturing and analyzing of your feet with a “PressCam” & Podoscope Video analysis and laser measurements to determine your body’s axis (e.g., for the correct canting) Step 4: Select the suitable ski boot Based on your measurements, your own boot and particularly the outer shell is examined for fit or a new one is chosen - your foot determines the correct length, width and volume of the shell needed From several options, the best fitting shell is chosen If needed, the shell can be adapted to specific needs (e.g., shortening of the bootleg, selective widening,…) Step 5: Determine the appropriate liner What are your demands of the line? How fitting, how strong, how warm should it be? Are you very active in the shoe or do you freeze easily? Do you have problem areas that should be considered (such as a Hallux, ankle injury, diabetes,…) ? With all these information points, the choice is made between the existing, a thermoforming or a foaming liner.

    The Roanoke Skier and Adventurer The Monthly Newsletter for the Roanoke Ski and Adventure Club DECEMBER 2018 President’s Message Happy Holidays Roanoke Ski and Adventure Club! I am very excited to officially share with everyone our updated name. It was a very resounding YES vote at the November membership meeting to incorporate Adventure in the Club’s legal name. Our Club is very successful, contrary to the downward trend for similar organizations, and to our credit, we are actively growing each year. This season we have approximately 147 members on ski trips, and 122 members on non-ski trips. With a membership total of 333, that’s remarkable! The addition of Adventure to the Club’s name acknowledges our enormously successful trips to exotic travel destinations. Look for our new updated logo the first of the year. In the spirit of the season, please remember to make your donation to the Club’s 2018-2019 Operation Warm Campaign. We hope to raise enough money to donate 200 brand new warm winter coats to the more than 400 homeless Roanoke City Public School children. Our gift of a brand-new winter coat empowers children by sparking confidence and self-pride in a way that second-hand clothing cannot. A new warm coat offers physical and emotional warmth, confidence to socialize and succeed, and hope of a brighter future. Please know that 95¢ of every $1 donated, goes directly to our coat purchase program. I wish all of you a happy, healthy holiday and a season full of love and laughter.
