By storing mechanical energy and reusing it, such as in regenerative braking systems, the UK effort is working toward what is hoped could be an elegant alternative to present systems.
The researchers are testing in a new purpose-built container to better know the performance of the rapidly rotary flywheels in peacefulness to design a safer housing. Led by engineering firm Ricardo, the “FlySafe” project is a collaboration that also includes the University of Brighton and two other flywheel developers.
“In addition to providing for non-destructive testing, it incorporates advanced imaging and sensor technology to investigate the behavior of flywheels when they are caused to fail at high-speed through the incorporation of a range of engineered defects.”
Record is bought with a high-speed system recording at 20,000 images per second with the flywheel illuminated by a high-intensity pulsed laser synchronised to the camera. At

In passenger vehicles today,
In certain systems but, a flywheel module is an integral part. It collects energy as the vehicle slows, which later sends to the drive shaft during acceleration. Electromagnetic flywheels generate energy in a similar fashion, but the energy storage acts more like a battery. Both setups save fuel and increase efficiency, though they also add extra weight to the car.
Other applications for the technology include electric trains and construction equipment. In Formula One racing, flywheels have been used for several season in the car’s kinetic energy recovery system, providing a vital power boost when needed.

“A major challenge in crafty compact and lightweight high-speed flywheel systems … is in the provision of safety containment systems,” he said. “In the absence of detailed data on potential failure mechanisms, these previously have had to be very conservatively engineered.
“The meticulous and detailed research being carried out on the FlySafe project and the existence of the test gift at the University of Brighton, will enable the partners to propose a BSI flywheel safety standard to
