A team of students, academics and technicians from Plymouth University are planning a renewed attempt on a land speed record in September 2016.
Mechanical and composites engineers and students had spent a year developing, building and testing an arm-powered vehicle ahead of the World Human Powered Speed Challenge in Battle Mountain, Nevada.
However, a pre-existing injury meant paracyclist Liz McTernan was unable to compete at full power on the Plymouth handcycle, nicknamed ‘Beluga’, although she was able to set a new women’s benchmark of 24.72mph on a conventional racing handcycle.
Instead, Lecturer in Mechanical and Marine Engineering Design Adam Kyte took to the controls of Beluga and, despite having never ridden a handcycle before, achieved a speed of 30.45mph.
Most importantly, the team managed to log data from sensors on the handcycle to analyse its performance, and work out how it can be optimised to perform even better ahead of a revised attempt next year.
Adam, who led the project alongside students Matthew Sharman (MEng Mechanical Engineering) and Oscar Whitmarsh (BEng Mechanical Engineering with Composites), said:
“Having spent many months creating Beluga, it was obviously disappointing not to see her pushed to her full potential. But testing on the best human powered vehicle racing course in the world gave us enough data to calculate what might be possible, and for an untrained and inexperienced pilot to reach more than 30mph shows what it could achieve in the future. Our sponsors and supporters have been incredible; they have made this amazing student experience possible, giving us a solid foundation to build on over the coming months.”
The design and production of the handcycle built on the previous student dissertation and project work over the past three years, and drew on specialisms ranging from aerodynamic and structural computer simulations to precision composite manufacturing techniques.
The handcycle has an aluminium frame and composite shell, and was constructed with the help of University technicians Julian Seipp, Richard Cullen, Rick Preston and Neil Fewings.
The whole endeavour was also made possible thanks to many sponsors and supporters who provided funding, equipment or services, including: XMA; Ipeco Composites; Baron Controls LLC; Certini Bicycle Company; Sunrise Software; University of Lincoln; Inspired Cycle Engineering; Cyclepowermeters.com. Additional funding has also been provided by Plymouth University’s School of Marine Science and Engineering.
“As students, this has given Matthew and I a unique opportunity. I spent most of my summer helping to build Beluga – really hard work that has given me a wide range of new skills, both practical and academic. We are already planning to get back to Nevada next September, and plan to recruit male and female handcyclists to ride Beluga to new world records at that competition. Beluga’s optimisation will be supported by two more dissertations focusing on internal improvements and weight reduction. We are also looking ahead to 2017, when all the knowledge gained over two years of competing will be drawn together to develop a new, even more streamlined handcycle shape.”
