Introduction
Geobrugg, a Swiss firm with over 50 years of expertise, is the world chief in producing high-tensile metal wire security nets and meshes. Their experience, honed in defending pure belongings and safeguarding lives throughout varied sectors, has now prolonged to the high-stakes world of motorsport. At this time, their state-of-the-art security techniques, put in on racetracks worldwide, instil confidence in each drivers and spectators, making certain their security. On this interview, we delve into the small print with Jochen Braunwarth, Geobrugg’s Director of Motorsport Options, to be taught extra concerning the firm’s improvements and the challenges they face within the fast-paced world of motorsport.
Jochen, to start out, might you introduce Geobrugg and its evolution into the motorsport sector?
Jochen Braunwarth: Actually, Daniel. Geobrugg has pioneered safety techniques for over 50 years, primarily specializing in pure hazards reminiscent of rockfall, slope stabilization, and avalanche obstacles. Our experience is rooted in creating options that handle high-energy impacts—whether or not that’s a falling boulder or, extra lately, a racing automobile at excessive velocity. About 15 years in the past, we had been approached by the FIA, the governing physique for world motorsport, to make use of our check services and expertise to judge present security merchandise out there. This marked our entry into motorsport, and since then, we’ve turn into more and more lively on this subject, bringing our intensive data of affect dynamics to racetrack security.
Geobrugg is now well-known for its motorsport security techniques. Are you able to inform us concerning the completely different techniques you present for racetracks?
Jochen Braunwarth: Initially, we began with everlasting installations like particles fences, with our first main challenge on the Sepang Worldwide Circuit in Malaysia. But it surely shortly grew to become obvious {that a} single product wouldn’t suffice for all racetrack wants. Totally different tracks require completely different options; metropolis circuits, as an example, want cellular particles fences for fast setups and teardowns. There’s additionally a necessity for strong pit wall techniques. Over time, we expanded our portfolio to offer a complete suite of services and products, together with consultancy, inspection companies, format design, and on-site assist throughout race weekends. We’ve developed right into a one-stop store, protecting the whole lot from preliminary consultations to post-installation companies, making certain that our shoppers really feel safe and well-supported.
How are these security fences examined to make sure they meet the rigorous calls for of motorsport?
Jochen Braunwarth: Within the early days, no testing was required, and the installations had been primarily based on specs that targeted on power. Nevertheless, coping with dynamic impacts – the place power absorption is important – is advanced and goes past mere calculations. One among our main assessments entails a 780 kg wrecking ball shot at 65 km/h immediately on the fence. This replicates a situation the place a Components 1 automobile, after a run-off, may turn into airborne and hit the fence. Nevertheless, since race vehicles, not wrecking balls, are the truth on tracks, the FIA later launched assessments utilizing a one-ton car at 120 km/h with a 20-degree affect angle. The purpose is to make sure that nothing breaches the three-meter security zone between the fence and the grandstand, safeguarding spectators.
Passing the FIA homologation course of sounds difficult. Are you able to share some insights into this?
Jochen Braunwarth: Certainly, it’s a rigorous course of. Thankfully, our lengthy historical past of coping with high-energy impacts offers us an edge. All elements of our techniques should work collectively seamlessly to cease a automobile or wrecking ball throughout the required three meters with out destroying all the fence. If the fence had been to be utterly destroyed, it could result in important race delays, which is unacceptable. Subsequently, a part of the homologation course of contains proving that our fences will be repaired shortly, inside a brief break between race periods, making certain minimal disruption. For instance, throughout a WEC occasion in Spa, our system was impacted however required no restore, whereas a close-by guardrail took two hours to repair.
How do the necessities differ between everlasting race tracks and momentary metropolis circuits?
Jochen Braunwarth: The principle distinction lies in set up and dismantling velocity. Metropolis circuits, like these in Chicago or Las Vegas, must be arrange and brought down shortly to attenuate disruption to native visitors and residents. For instance, the Chicago observe for NASCAR was put in in simply two weeks and dismantled in a single and a half weeks. This calls for exact logistics and planning. However, everlasting circuits just like the Hungaroring supply extra time for set up, which reduces the strain however nonetheless requires meticulous planning since our options are sometimes the final to be put in earlier than a race.
Are there any ongoing R&D efforts at Geobrugg for future developments in security techniques?
Jochen Braunwarth: We’re all the time striving to boost our merchandise. Motorsport will all the time contain threat, however our purpose is to mitigate it as a lot as doable. Presently, we’re engaged in R&D to enhance system efficiency and combine completely different components extra successfully. For instance, we’re exploring methods to make life simpler for photographers by offering versatile openings within the fences. Furthermore, we’re contemplating combined actuality as a software for patrons to visualise our merchandise in real-world settings earlier than set up. This dedication to innovation ought to make our viewers really feel optimistic about the way forward for racetrack security.
What has been the most important problem for Geobrugg in Components 1?
Jochen Braunwarth: One of many greatest challenges is altering mindsets, significantly at established services. Many have been working with the identical contractors for many years, so convincing them to attempt one thing new can take time. Within the U.S., for instance, it took about 5 to 6 years of persistent effort to get some venues to present our options an opportunity. The resistance was primarily as a result of concern of change and the assumption that their present techniques had been enough. As soon as they did, they noticed the distinction and embraced the brand new expertise. We’re additionally exploring methods to make our merchandise extra relatable and simpler to grasp, probably via combined actuality, to assist prospects visualize their future racetracks and the security techniques in place earlier than they’re even constructed.
Conclusion
Innovation and an intensive understanding of affect dynamics have marked Geobrugg’s transition from pure hazard safety to motorsport security. Jochen Braunwarth’s insights reveal the complexity and dedication behind making certain that each racetrack is as protected as doable, permitting the joys of motorsport to proceed with out compromising the security of these concerned. As Geobrugg continues to push the boundaries of what’s doable, the way forward for racetrack security seems to be each promising and safe.
