Testing ahead of Bloodhound SSC land speed record attemptPrecision sensor manufacturer Micro-Epsilon UK has become a Product Sponsor of the Bloodhound SSC Project - the 1,000 mph land speed record attempt that is scheduled to take place in 2016. Micro-Epsilon UK will provide high precision sensors and measurement systems for the Bloodhound SSC Project that will be used throughout the testing, production and operational stages.
Micro-Epsilon's capaNCDT 6200 high precision capacitive measurement system has been identified for in-house testing to assess and validate the dynamics and mechanical expansion of the Bloodhound SSC wheels. As Joe Holdsworth, systems engineer at Bloodhound Programme Ltd states: "With the wheels turning at speeds of up to 10,000 rpm, this causes extremely high stresses in the wheel materials, which are solid aluminium alloy. We need to validate our FEA stress models with reality and so we needed a high precision measurement system that could measure the mechanical expansion of the wheels accurately at high speed. We came across Micro-Epsilon's capaNCDT 6200 measurement system at a recent trade exhibition and liked the fact that the system would enable us to synchronise measurements from all four wheel sensors during tests."
Also, Micro-Epsilon's optoNCDT 2300 series of laser displacement sensors will be used for on-vehicle testing of Bloodhound SSC during both runway trials and the record attempt itself. Holdsworth comments: "Measuring the ride height is a critical measurement parameter on the car. We need to know the exact distance between the wheels and the ground to see how far into the ground the wheels sink during trials."
Mounted to the car's chassis with the laser window pointing down towards the ground, the optoNCDT 2300 high speed sensor will accurately measure and monitor the ride height of the car. The sensor will enable the Bloodhound SSC team to adjust the suspension characteristics in order to optimise the performance of the car.
