According to GlobalData’s Technology Foresights, which uses over 206,000 patents to analyze innovation intensity for the aerospace and defense industry, there are 110 innovation areas that will shape the future of the industry.

CMC turbines is a key innovation area in advanced materials

CMC turbines refer to turbines that incorporate ceramic matrix composite (CMC) materials in their construction. CMCs combine ceramic fibers with a ceramic matrix, using methods such as filament winding, braiding or knotting. They provide significant durability and heat resistance capabilities, all while having on average one-third of the material density of metal alloys traditionally used in turbine design. These newer types of turbines utilize CMC components such as brake components, flow passages, joint structures, and blade tracks to improve performance and durability. They also require less cooling, which has helped companies such as General Electric and Rolls-Royce to simplify some aspects of engine design.

GlobalData’s analysis also uncovers the companies at the forefront of each innovation area and assesses the potential reach and impact of their patenting activity across different applications and geographies. According to GlobalData, there are 50+ companies, spanning technology vendors, established aerospace and defense companies, and up-and-coming start-ups engaged in the development and application of CMC turbines.

Key players in CMC turbines – a disruptive innovation in the aerospace and defense industry

‘Application diversity’ measures the number of applications identified for each patent. It broadly splits companies into either ‘niche’ or ‘diversified’ innovators.   

‘Geographic reach’ refers to the number of countries each patent is registered in. It reflects the breadth of geographic application intended, ranging from ‘global’ to ‘local’.
