Electrification and power electronics have become one of the central pillars of innovation in the Aerospace, Defence and Space (ASD) sectors. The convergence between mechanical and electrical engineering is driving more efficient, sustainable solutions capable of addressing the technological challenges of the future. This integration not only redefines propulsion, control, and onboard energy systems, but also enhances the competitiveness of the entire industrial value chain.
Electrification: a structural revolution in advanced systems
Electrification in the ASD context goes far beyond replacing traditional components with electrical ones. It is about rethinking the entire system architecture to maximise performance and minimise energy consumption, without compromising reliability or safety.
In aviation, for example, electrification is driving the development of hybrid and electric propulsion systems, moving towards greener and more efficient aircraft. In defence platforms, integrated electrical systems enable more precise and resilient management of distributed energy loads. In space applications, electrical energy management is a critical factor to ensure long-duration autonomous operations in extreme environments.
Mechanical and electrical engineering, working in synergy, makes it possible to design structures and subsystems where energy efficiency and operational reliability are prioritised.
Power electronics: the heart of modern energy systems
At the core of electrification lies power electronics: the set of technologies that enable the conversion, regulation, and control of electrical energy with unprecedented efficiency and precision.
Power converters, inverters, and electronic controllers are essential for managing energy flows in aerospace and defence systems, where operating conditions are dynamic and highly demanding. Thanks to advances in wide-bandgap semiconductors (such as SiC and GaN) and digital control techniques, power electronics systems now offer:
- High energy efficiency, reducing losses and increasing autonomy
- Higher power density, enabling more compact and lightweight designs
- Optimised thermal control, critical for long-term reliability in aerospace environments
The interaction between mechanical engineering and power electronics not only optimises system performance, but also enables new capabilities that were unthinkable just a few years ago.
Impact on defence, space, and commercial aviation
Electrification and power electronics have profound implications across the three main ASD domains:
Commercial aviation:
Electrification programmes are accelerating the development of more efficient electrical subsystems, reducing fuel consumption and emissions. This is key to meeting increasingly strict environmental standards and sustainability expectations.
Defence:
Land, naval, and air platforms are adopting highly integrated electrical energy systems that improve the management of critical loads and enhance responsiveness and resilience in complex operational scenarios.
Space:
Electrical energy management in satellites and spacecraft is essential to ensure long-term operations. Advanced power electronics maximise the efficiency of solar panels, manage high-performance batteries, and guarantee the operational redundancy required for long-duration missions.
Towards a more efficient and sustainable industrial future
Electrification and power electronics are not just technological trends—they are enablers of competitiveness. Leading industries are integrating these disciplines to reduce operational costs, improve overall system performance, and proactively respond to sustainability requirements.
Collaboration between mechanical and electrical engineers—supported by digital design methods, advanced simulation, and virtual testing—is positioning the most innovative integrators at the forefront of technological evolution in the ASD sector.
The era of electrification and power electronics is redefining engineering in Aerospace, Defence, and Space. It is an opportunity to transform systems, optimise performance, and build more efficient solutions ready for tomorrow’s challenges.
In this process, advanced mechanical and electrical engineering capabilities play a strategic role, merging knowledge, precision, and innovation to support the sector’s evolution.
