The Rostec State Corporation and Peter the Great St. Petersburg Polytechnical University used space developments to create sport sleds.
They were created at the request of the three-time World Champion and two-time Luge World Cup winner Roman Repilov.
Unique materials based on glass and carbon fillers gave the sled the necessary strength, stiffness and aerodynamic properties.
“It may seem that the sled is a simple construction. In reality, every detail, shape, angle of inclination, material quality and other nuances determines a lot. The sled is built like a real aircraft, with the involvement of designers from different industries. An important task was to find the best composition of materials and geometric solutions.” – said Ekaterina Baranova, communications director of Rostec.
The fairing brackets of the carriage can withstand pressures up to 5G, which is comparable to overloading during aerobatics of a supersonic fighter. They are made of an increased strength alloy, which is important when traversing the track at a speed of 130–150 km/h.
And for the skids, steel was used, which is used, among other things, for the manufacture of railway rails, tank tracks and rollers for asphalt pavers. There are no analogues of Hadfield steel in Russia.
