The aerospace industry has long recognized the transformative potential of the Internet of Things (IoT) and has been actively integrating it into its operations. However, for many years, the sector struggled with high maintenance costs, especially when it came to large engines powered by high-octane hydrocarbons. According to Boeing, each aviation engine manufacturer wastes around $40 billion annually on maintenance. The IoT is now offering a game-changing solution through advanced sensor systems that are revolutionizing how aircraft engines are monitored and maintained.
One of the most impactful applications of IoT in this field is predictive maintenance. Rolls-Royce was among the first companies to implement this concept over 20 years ago. By using IoT sensors to detect issues before they escalate, companies can significantly reduce downtime and repair costs. Predictive maintenance not only improves operational efficiency but also enhances safety. Thomson Reuters estimates that this approach could save billions of dollars annually for aerospace firms.
Beyond aviation, IoT-based predictive maintenance is also making waves in other transportation sectors. For example, Siemens Germany uses the Railigent digital system to monitor rail vehicles. This system leverages IoT sensors to identify potential problems before they occur, allowing maintenance teams to respond proactively. By analyzing data from sensors, the system can predict and alert about abnormal behaviors in the system, ensuring smoother operations and reducing unexpected failures.
In aircraft engines, digital sensors continuously monitor critical parameters such as temperature, fuel levels, air pressure, and more. This real-time data enables maintenance crews to stay informed and make better-informed decisions. For instance, Pratt & Whitney’s latest engine, the PW1000G, contains 40% more sensors than previous models. The engine sends a data packet every 2.5 seconds, allowing for precise scheduling of maintenance tasks.
Bombardier’s C-Series jet engine, introduced in 2015, features over 5,000 sensors that transmit approximately 10GB of data per second. This massive amount of data is crucial for improving the safety, reliability, and performance of modern aircraft. Companies are now leveraging this data to refine their systems and enhance overall flight efficiency.
General Electric’s IoT-based Flight Efficiency Services is another example of how the technology is reshaping the industry. Through the use of IoT and predictive analytics, GE helps airlines save up to 2% in annual fuel costs. Over the past 15 years, GE has collaborated with Alitalia to develop systems that optimize fuel usage and improve overall performance.
Another area where IoT is making an impact is in-flight entertainment and connectivity (IFEC). With the rise of high-speed networking equipment on passenger aircraft, passengers now enjoy seamless internet access and enhanced entertainment options. This transformation is largely driven by the IoT, which enables smarter and more connected in-flight experiences.
The influence of IoT on the aerospace industry is just beginning. According to a report by GE, nearly 37% of airlines worldwide are already investing in IoT technologies. This number is expected to grow significantly in the coming years, with projections suggesting that over 58% of airlines will allocate resources to IoT initiatives. As the industry continues to evolve, the integration of IoT will play a central role in shaping the future of aviation.
