 Manchester Metrology, acknowledged experts in precise laser scanning and data capture, is working with a team intent on breaking again the world record for women on a conventional motorcycle over a standing start mile.
Held by Scunthorpe-based Becci Ellis the record is 264.1 mph, set by her at Elvington airfield in North Yorkshire on a 1300cc Suzuki Hayabusa. Prior to the record breaking run the Hayabusa was highly modified by her husband, Mike Ellis, with the help of volunteers and sponsors. It enabled it to generate 650 bhp.
That was back in 2014 and Becci is now preparing for a new attempt to raise her own record. Modifications to the Hayabusa now include to the aerodynamics of both bike and rider.
The team is using advanced virtual simula- tion techniques in its attempt to reduce aerodynamic drag – and GTMA supplier Manchester Metrology is undertaking the critical scanning routines of bike and rider to gather the raw data needed to give the best possible virtual simulation outcomes.
Mike Ellis said: “Aerodynamic drag is a strong, unwelcome force that increases with the square of the speed, therefore as the speed we achieve doubles, drag quadruples. Given the high speeds that we are looking to achieve, it is obvious that much attention needs to be paid to this vital area.”
Helping in the task is Northumbria
University's Department of Mechanical and Construction Engineering, led by Professor Robert Dominy, a specialist in aerodynamic virtual simulation.
The raw data he needs for analysis is being gathered by Manchester Metrology which is using an advanced FARO Edge ScanArm HD laser scanner to scan all aspects of the bike/rider combination and to generate the required files.
“A major advantage for us has been that the software used by Northumbria University can instantly indicate where our aerodynamic weaknesses are and provide invaluable feedback on how to improve our designs.”
Philip Knowlson of Manchester Metrology said: “Given our need to perform multiple, highly precise scans of the motorcycle and

rider and to generate the vital data required for aerodynamic virtual simulation purpos- es, we chose to use an Edge ScanArm HD. “The advanced FARO product was ideal for this application as it has an exceptional scan rate of up to 560,000 points/second.
“Also, given the range of different materials we needed to scan, including the bikes far- ing, wheels and tank, also the rider in her leathers and helmet, it was a major advan- tage that the Edge ScanArm HD is able to perform precise scanning routines across a range of diverse surface materials without any surface preparation or targets.”
The advanced Edge ScanArm HD is an advancement in FARO’s popular ScanArm product range and provides point cloud capture with rapid speed, superior resolu- tion and high accuracy. It combines the convenience of a FaroArm with the power of a Laser Line Probe creating a flexible, high performance contact/non-contact portable measurement system.
New functionalities allow users to seam- lessly scan across diverse surface materials regardless of their contrast, reflectivity or part complexity, without the need for spe- cial coatings or target placements.
Although relevant to endless other applica- tions, common uses include reverse engi- neering, certification, prototype part scan- ning, first article inspection and periodic part inspection.
