The aerospace and defense industry continues to be a hotbed of patent innovation. Activity is driven by automation, environmental sustainability, and operational efficiency, and the growing importance of technologies such as artificial intelligence (AI), Internet of Things (IoT), drones, and satellites. In the last three years alone, there have been over 84,000 patents filed and granted in the aerospace and defense industry, according to GlobalData’s report on Innovation in defense: active noise reduction propellers.

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 stabilizing 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.
110 innovations will shape the aerospace and defense industry
According to GlobalData’s Technology Foresights, which plots the S-curve for the aerospace and defense industry using innovation intensity models built on over 260,000 patents, there are 110 innovation areas that will shape the future of the industry.
Within the emerging innovation stage, missile aerodynamic guidance, aerial cargo delivery, and underwater ROVs are disruptive technologies that are in the early stages of application and should be tracked closely. UAV fuselage, multi-mode regenerative fuel cells and aircraft power distribution network are some of the accelerating innovation areas, where adoption has been steadily increasing. Among maturing innovation areas are aircraft power management and rocket engine assembly, which are now well established in the industry.
Innovation S-curve for the aerospace and defense industry
Active noise reduction propellers is a key innovation area in aerospace and defense
Active noise reduction propellers are devices, systems, and methods used to control, reduce, and/or alter the sound generated by propellers of aerial vehicles, such as unmanned aerial vehicles (UAVs), during operation. This can be achieved through various techniques, including adjusting the speed and phase of the rotor units, using acoustic resonators, incorporating sound dampening materials and propeller blade treatments, applying transducers to generate anti-sounds, and actively adjusting the position and/or configuration of propeller blades.
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 15 companies, spanning technology vendors, established aerospace and defense companies, and up-and-coming start-ups engaged in the development and application of active noise reduction propellers.
