How do a tunnel, thousands of helium-filled soap bubbles and laser lighting help skaters to go for gold🥇at #beijing2022 ? TU Delft, NOC*NSF ,KNSB and Innovation Lab Thialf analysed the Dutch top skaters on the ice of Thialf last week. The measuring system, called 'Ring of Fire', has been used to measure and visualise air resistance around moving skaters. In the video Andrea Sciacchitano, #aetudelft ass. Prof. explains how it works. The Ring of Fire is a tunnel containing thousands of bubbles filled with helium through which the skaters skate. Lighting up these bubbles with a laser and taking photographs really quickly with a high-speed camera enables us to create a precise image of the airflow around the moving skaters. Wouter Terra, researcher at #aetudelft and NOC*NSF says: "The Ring of Fire is unique, because it is the only measuring device in the world that can determine the exact air resistance of a moving skater. Up to now it was only possible to measure the air resistance in a wind tunnel in which the skater is standing still.
