However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early emergence to accelerating adoption, before finally stabilising and reaching maturity.

Identifying where a particular innovation is on this journey, especially those that are in the emerging and accelerating stages, is essential for understanding their current level of adoption and the likely future trajectory and impact they will have.

180+ innovations will shape the aerospace and defence industry

According to GlobalData’s Technology Foresights, which plots the S-curve for the aerospace and defence industry using innovation intensity models built on over 262,000 patents, there are 180+ innovation areas that will shape the future of the industry.

Within the emerging innovation stage, hydrogen fuel cells, aircraft powertrain control, and fuel cells for aircrafts are disruptive technologies that are in the early stages of application and should be tracked closely. EV charging stations, hybrid propulsion aircraft engines, and electric aircraft charging interfaces are some of the accelerating innovation areas, where adoption has been steadily increasing. Among maturing innovation areas are fuselage frame modelling and powered wheels for aircraft landing, which are now well established in the industry. 

Innovation S-curve for environmental sustainability in the aerospace and defence industry

Reformer integrated fuel cells is a key innovation area in environmental sustainability

Reformer fuel cells use a catalytic process to enhance the efficiency of the overall cell.

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 40+ companies, spanning technology vendors, established aerospace and defence companies, and up-and-coming start-ups engaged in the development and application of reformer integrated fuel cells.

Key players in reformer integrated fuel cells – a disruptive innovation in the aerospace and defence industry

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

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