International competition: Torpedo drilled its way in to the final

Being faster than a snail is really a tremendous challenge for a tunnel boring machine. Students at DHBW Mosbach have mastered this, and have made it through to the final of an international competition with the ?Dirt Torpedo?. WIKA co-sponsored the project by giving measurement technology and a grant.
Students at DHBW Mosbach proudly presented their ?Dirt Torpedo?. DHBW Gripping . Dr. Gabi Jeck-Schlottmann, Gerhard Lauth, Managing Director of the Pro DHBW Mosbach foundation, and CEO of WIKA Alexander Wiegand SE & Co. KG, Alexander Wiegand, also attended the presentation of the innovative tunnel boring machine.
Tunnel boring machine made it in to the final round
Of the total of 400 entries in your competition, called by the American entrepreneur Elon Musk (co-founder of Tesla among others), twelve made it through to the final round. The finalists were tasked with drilling a 30-metre-long tunnel in California?s Mojave Desert. However, because of conditions being changed on-site at short notice, only the crew from TU Munich could actually start. The students at DHBW Mosbach were disappointed concerning the way your competition ended, which was, ultimately, not a competition at all. Nevertheless, they are justifiably pleased with their ?Dirt Torpedo?.
Student competition project with WIKA measurement technology
The team spent per year working on the 2 2.63-metre-long tunnel boring machine. The ?Dirt Torpedo? progresses at a speed of 5.4 metres per hour. That?s one metre greater than a snail ? and snails are often faster than a conventional tunnel boring machine.
WIKA?s measurement technology is located in the rear section of the ?Dirt Torpedo?. From there, a fibre-reinforced, fast-curing concrete is pressed contrary to the tunnel wall through twelve valves to aid it. To monitor the pressure of the concrete feed, WIKA provided twelve diaphragm seal systems with mounted transmitters of model S-20 and a 1?10 V output signal. The flush diaphragms of the diaphragm seals are extra strong so they can permanently resist the abrasive forces of the concrete. No residues can adhere to their surface. WIKA?s sponsorship of the ?Torpedo? project amounts to a total of 20,000 euros.
Long-term collaboration with the cooperative state university
The business and DHBW Mosbach have already been closely associated since 1985. As a dual partner, WIKA enables future specialists to graduate in a current total of seven degree programmes, with practical phases at WIKA?s headquarters in Klingenberg. So far, around 250 WIKA students have graduated from the DHBW. WIKA also offers the status of a ?Gold Partner?, this means it provides the university with ?a fantastic level? of support. Partner companies are involved in the university through the Pro DHBW Mosbach foundation, and thus promote the dual system. Furthermore, Alexander Wiegand is the Chairman of the Board of Trustees.
