Unitsky String Technologies

19 June 2016

The basis of SkyWay technology is innovative string rail

A flat rail head and a cylindrical steel wheel ensure minimal energy consumption for movement.

Power of unibus wheel rolling resistance with weight of 5,000 kg at the speed of 450 km/h:

W_w.r. = M × g × k_w.r. × V = 5,000 kg × 9.81 m/s² × 0.0015 × 125 m/s ≈ 9,2 kW

Compare: when using pneumatic machines with k_w.r. = 0.18 (for V = 450 km/h), W_w.r. ≈ 1100 kW

Types of string rails and corresponding track structure designs

Flexible rail and flexible uncut track structure:
