Strong and lightweight composite transmission shafts for aerospace

CTG's transmission systems provide a light weight alternative to metal

Transmissions

CTG realised that the aerospace market would not favour reliance upon adhesives joining the metal flange to the composite structure. Therefore the company developed a patented composite to metal interface which allows the reliable transfer of torque with zero reliance upon adhesives, reducing risk of failure. CTG has also developed other elements for a transmission shaft system, including universal joints and TORQdisc couplings; these further contribute to part reduction and weight savings.

Transmission Shafts

Transmission Shafts

As well as being lightweight, composites are extremely strong which means the transmission shafts are scalable, resulting in a reduction in parts and subsequent further weight savings. Using CTG’s patented joining technology the transmission shafts are on A330, A340, A350, A380 and A400M, Bombardier C-Series, Boeing 787 and JSF F-35.
TORQdisks and Universal Joints

TORQdisks and Universal Joints

TORQdiscs are lightweight composite flexible couplings used in power transmission applications; specially within the actuation systems of aircraft wings. The assembly provides lower weight than an equivalent crowned spline joint, a reduction in system axial loads as result of compliance, zero maintenance, zero backlash, low power loss, low wear, high fatigue resistance and fast, flexible installation. TORQdiscs are fully scalable for different torque requirements. This technology currently features on the Bombardier CSeries.
