Predictive maintenance research at Cranfield University: A PhD perspective

Imagine a world where jet engines don’t just fly, they predict their own maintenance needs. That’s the future Felix Fu is working towards as part of his PhD at Cranfield University, the epicentre of innovation in transport systems.

Why Cranfield?

Cranfield wasn’t just the perfect academic fit; it was a passport to a global adventure. Chosen as one of 15 researchers for the prestigious Horizon 2020 MSCA MOIRA project, I found myself collaborating with top companies like Rolls-Royce and Airbus. This project, focused on advanced diagnostics and prognostics, perfectly aligned with my passion for bridging the gap between research and real-world applications.

My journey unfolds

My PhD journey has been anything but ordinary. From presenting my work at international conferences to specialised training sessions like Bayesian Machine Learning at Oxford, Cranfield has opened doors to incredible opportunities. But the real highlight? The chance to blend technical development with European travel, exploring the canals of Venice, the Guggenheim Museum in Bilbao, and even trekking the Dolomites! This unique blend of academics and adventure fuels my research fire.

Predicting the future of aviation safety

My research focuses on a “hybrid prognostic methodology,” a blend of physics-based models and innovative data-driven techniques. Imagine this: a crystal ball for aviation systems, predicting the health of critical components like gas turbines with incredible precision. This translates to reduced downtime, enhanced safety, and lower operational costs for airlines worldwide.

Beyond the lab

My research isn’t confined to theory. Collaborations with Rolls-Royce and open datasets from NASA ensure every model and simulation is grounded in real-world challenges. From the lab to the runway, my work is tested, refined, and applied where it matters most. My findings, published in seven peer-reviewed papers, are already contributing to global conversations on predictive maintenance, pushing boundaries and ensuring every flight is a little safer.

A day in the life of a PhD researcher

My days are a mix of innovation, collaboration, and adventure. Mornings begin with data analysis and refining models, sometimes followed by teaching MSc students—sharing my knowledge is part of the thrill. Afternoons brim with brainstorming sessions with peers, workshops like personal effectiveness training, and even condition monitoring courses across Europe.

My secondments at Tetra Pak and IKERLAN weren’t just about research; they were cultural immersions, allowing me to savour local delicacies and explore breathtaking landscapes.

Fuelling innovation: The Cranfield advantage

The Cranfield Doctoral Network is a melting pot of ideas. It has connected me with researchers across disciplines, enriched my teaching experience, and broadened my professional horizons. Cranfield’s commitment to bridging academia and industry ensures research translates into real-world impact.

Cranfield’s global impact

Cranfield is redefining transport systems and sustainability on a global scale. Through revolutionary research and collaborations, we tackle pressing issues in aviation safety and efficiency, while promoting sustainable solutions.

 Beyond the PhD

After completing my PhD in 2025, I envision leading research on safer and more sustainable transportation systems. Whether in academia, industry, or consultancy, I aim to utilise my skills and global network to solve critical challenges, foster international collaborations, and be at the forefront of predictive maintenance innovation.

Advice for aspiring researchers

“Dive in with curiosity and an adventurous spirit! Transport systems research demands both technical expertise and creative thinking. Embrace international collaborations and soak up the world’s diverse perspectives. But remember, balance is key. Don’t let the hard work overshadow the joy of exploration—whether it’s conquering a ski slope, indulging in local cuisine, or making lifelong friends.”

A fun fact

When I’m not refining models, you’ll find me carving up the slopes snowboarding or engaging in a friendly fencing bout. The research might be cutting-edge, but I believe life’s journey should be a balance between challenge and joy—just like my research.
