Engineering excellence from legacy turbines to next-gen aero-engines

Aerospace and Defense propulsion system manufacturers face a dual challenge:

• Ensuring the performance and availability of legacy engines that drive aftermarket revenues.
• Accelerating innovation toward greener engines, such as electric and hydrogen propulsion, to meet net-zero targets.

Mechanical mastery powering aerospace innovation

The aeronautics, space and defense sectors are undergoing a major transformation, driven by increasing system complexity, ambitious sustainability targets, and rapid digitalization.

Empowering systems with safe and high-performance code

Aerospace and Defense programs increasingly rely on embedded software to deliver performance, safety, and competitiveness. Yet, software complexity is growing exponentially — systems must process more data, respond in real time, integrate with hardware, and comply with the strictest certification and cybersecurity standards.

Smarter embedded systems for innovation and reliability

In Aerospace & Defense, electronics are evolving at high speed — driven by electrification, embedded intelligence, and digital continuity. To stay ahead, OEMs and suppliers must deliver increasingly complex, connected systems while meeting ever-stricter safety, qualification, and cybersecurity requirements.

Agile and sustainable manufacturing for a new industrial era

The aerospace and defense industry is facing a decisive industrial shift, driven by production acceleration, digital transformation, and environmental transition.

Data-driven strategies to secure and streamline aerospace production

Aerospace and defense players navigate unprecedented production ramp-ups while facing disrupted supply chains, geopolitical uncertainty, and rising sustainability demands. Tier-1 and Tier-N suppliers encounter bottlenecks, part shortages, and fragmented systems, all threatening delivery performance and program timelines.

Ensuring system integrity with sovereign and secure-by-design solutions

In an era of growing geopolitical tension, digital interdependence, and increasingly sophisticated cyber threats, sovereignty and cybersecurity have become strategic imperatives for aerospace, defense, and critical infrastructure stakeholders.

Mastering complexity to deliver impactful results

Aerospace and defense programs are growing in complexity. Accelerated time-to-market, on-time delivery, and competitiveness require managing extended value chains and evolving risks.
