Rostec and a Russian Polytechnical University Drive Innovation in Sport Sleds
Space-inspired research and advanced materials are at the heart of a groundbreaking sled project created by the Rostec State Corporation in collaboration with Peter the Great St. Petersburg Polytechnic University. The effort leveraged space developments to design high-performance sport sleds that blend cutting-edge science with practical competition needs. The project was driven by the ambition of Roman Repilov, a three-time World Champion and two-time Luge World Cup winner, who sought sleds that could push the boundaries of speed, stability, and control on demanding tracks. The resulting frames and runners use unique materials based on glass and carbon fillers to deliver the required strength, stiffness, and aerodynamic efficiency that top luge athletes demand.

The engineering team approached the sled as a complex machine rather than a simple frame. Each detail matters: the shape, the angle of inclination, the quality of materials, and countless other nuances influence performance. The design process mirrored aircraft development, bringing together specialists from diverse industries to refine every facet of the sled. An essential objective was to identify the optimal blend of materials and geometric configurations that would perform reliably under race conditions. Ekaterina Baranova, the communications director for Rostec, underscored this philosophy, noting the multidisciplinary collaboration involved in achieving a superior balance of strength, weight, and aerodynamics.

The fairing brackets of the carriage are engineered to withstand pressures up to five Gs, a capability comparable to the extreme loads experienced during aerobatic maneuvers of fast jets. This robustness is crucial when the sled travels at speeds between 130 and 150 kilometers per hour on icy tracks. The brackets are crafted from an enhanced-strength alloy designed to endure the rigors of luge racing, including rapid accelerations, tight turns, and sustained high-speed stability on challenging curves.

For the runners, steel was selected for its proven durability and proven performance in demanding transportation applications. The steel is drawn from a class used in railway rails, tank tracks, and asphalt paver rollers, ensuring exceptional wear resistance and longevity. Remarkably, the Hadfield steel variant used in these sleds has no direct analogue in Russia, highlighting the project’s pursuit of distinctive, high-performance materials. This choice supports consistent glide over ice and reduces the maintenance demands that can disrupt competition schedules. [Rostec press release]
