The aerospace and defence industry continues to be a hotbed of innovation, with activity driven by the uptake of advanced technology, and growing importance of technologies such as hypersonics and advanced materials. In the last three years alone, there have been over 174,000 patents filed and granted in the aerospace and defence industry, according to GlobalData’s report on Innovation in Aerospace, Defence & Security: Turbo engine dampeners.

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, bonded fibre laminates, thermoplastic elastomer laminates, and vibration supression devices are disruptive technologies that are in the early stages of application and should be tracked closely. Centrifugal fan impellers, ceramic composite laminates, and gas turbine engine testing are some of the accelerating innovation areas, where adoption has been steadily increasing. Among maturing innovation areas are protective blade coatings and blade alloy welding, which are now well established in the industry.

Innovation S-curve for the aerospace and defence industry

Turbo engine dampeners is a key innovation area in aerospace and defence

Dampeners are needed for turbo engines in order to reduce the vibrations that are caused by turbochargers. Turbo engine dampeners consist of bellows and wire mesh which act to reduce the high-frequency vibrations.

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 10+ companies, spanning technology vendors, established aerospace and defence companies, and up-and-coming start-ups engaged in the development and application of turbo engine dampeners.

Key players in turbo engine dampeners – 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’.

Safran is one of the leading patent filers in turbo engine dampeners. Safran and its subsidiaries have been filing numerous patents related to turbo engine dampeners. Many of these are exploring ways to dampen turbo engines on aircraft, as well as more niche technologies including damping fluid films, and viscose damping. Some other key patent filers in the industry include Rolls-Royce, Raytheon Technologies, and General Electric.

In terms of geographic reach, Sulzer leads the pack. Moog and Porsche Automobil stood in the second and third positions, respectively. By means of application diversity, Porsche Automobil held the top position, followed by Garrett Motion, Safran, Moog, and Raytheon Technologies.

Development of turbo engine dampeners, when examined through the lens of patent filings, is being driven by industries that manufacture and use engines – the aerospace and defence, and automotive industries being the most significant of these. Subsequently, filings are present from companies in both these industry groups.
