Design and Analysis of Ski Jumps


Summary

Little safety driven engineering goes into the design and construction of ski and snowboard jumps in terrain parks at publicly accessible ski resorts. Catastrophic injuries and even deaths occur during skiing and snowboarding at these resorts. It is possible to design the landing surfaces of jumps such that the normal impact velocity on landing is capped at a safer value regardless of the jumper's takeoff speed and jump launch speed. These jump designs can still provide large maximum heights and flight durations for participant fun. We have designed a web application that laypeople can use to design and analyze ski jumps with specified equivalent fall height in mind.
