Sigma continues to seek out innovative ways of reducing weight and manages this under the brand of Sigma Lite. Components in the range include composite pipes, lightweight end fittings and drive shafts, offering substantial weight savings compared to conventionally-manufactured counterparts.
The star of the Sigma Lite range is COMPipe – a composite aero-engine pipe that delivers weight savings of 50% over traditionally-manufactured pipes. The result of a CleanSky funded programme, COMPipe is capable of withstanding operating temperatures up to 165°C, operating pressures of up to 450 psi and a typical engine operating environment, including fireproof requirements.
The range also includes lightweight end fittings – a variation of Sigma’s successful self-locking nuts, concept designs for metallic end-fittings produced using additive manufacturing techniques, and composite drive shafts.
