Advanced composite flywheels

CTG designs and manufactures industrial flywheels for kinetic energy storage systems, these are used for uninterruptible power supply systems for critical buildings. The flywheels give very high energy storage density by comparison to batteries and also have very low service costs. Composite flywheels have a life of about 15 years and are also unaffected by the number of charge/discharge cycles.

The main application of composite flywheels is to provide back-up power until the mains power starts again or another sufficient power supply is started, for example a diesel generator. Flywheels can generally discharge at 100kW for a period of 15 seconds and also recharge immediately at the same rate, this provides 1-30 seconds of buffer time as generators usually start up between 5-25 seconds. This type of system is invaluable for buildings like hospitals and military instillations.

CTG also produces advanced composite components for turbo-machinery, high speed motors and generating sets. They are used to retain magnetic and metallic components in high speed rotating structures. Carbon composites are non-magnetic, low mass and ideal for retaining magnets in permanent magnet motors and generator applications.

Flywheels can be adapted to many different applications including KERS or Kinetic Energy Recovery Systems for use in F1. The change of rules in F1 for 2009 means that some kind of energy recovery system must be used.

"5.2.3 The maximum power, in or out, of any KERS must not exceed 60kW. Energy released from the KERS may not exceed 400kJ in any one lap. Measurements will be taken at the connection to the rear wheel drive train." (Sourced from www.FIA.com)

CTG's strict quality systems allow us to design and manufacture high performance products for critical industries. We currently meet the standards of ISO/TS16949:2002 and exceed the standard set by our  AS9100 and ISO9001:2000 accreditations. Our strong business structure and internal resources makes us an ideal partner for developing products in numbers from one to tens of thousands.
