Centre of Excellence

Recognising the R&D opportunities arising from the extensive and proven technological capabilities of TLT MechCaL, TLT-Turbo established the TLT MechCaL Centre of Excellence (COE) for the global TLT brand in Pretoria, South Africa.

Research & Development

TLT MechCaL have been researching and implementing the use of various Carbon Fibre Reinforced Plastics – generally referred to as composite materials – in their fan designs for over a decade. The use of these materials and knowledge of aerodynamic principles with the majority of the TLT MechCaL team having their background in the aircraft industry, have allowed TLT MechCaL to design and manufacture fans with significant improvements in performance with an increase in efficiency, resulting in lower energy consumption, lower mean time between failures, and less demanding maintenance.

The TLT MechCaL COE is committed to the development of equipment and production processes for producing the fan components. These include components that are currently manufactured in steel such as the nose cones and aerodynamic fairings that can be made with composites as well.

Our testing facility equipment includes a laser measuring arm, tensile and impact testers, a large blade static and fatigue test bench and some non-destructive testing (NTD) capability with ultrasound and a dedicated Infra-Red thermography setup.

Advanced Materials & Composite Blades

Composite materials – or composites – are engineered materials made from two or more constituent materials with significantly different physical or chemical properties and which remain separate and distinct on a microscopic level within the finished structure. TLT MechCaL uses combinations of materials to form our products to ensure suitable mechanical properties. Combinations of carbon fibre, glass fibre, Kevlar, polyurethane and metal, and metal castings are used.

The TLT MechCaL COE capabilities:
  • Production of light-weight composite fan blades
  • Production of full composite fans (both axial flow and centrifugal fans)
  • Advanced composite stress analysis
  • Wear & corrosion analysis
  • Fatigue & impact property analysis
