Conception et développement aéronautique

Optimize every aspect of aerospace design—where performance, weight and compliance are mission-critical—with a digital twin. You can can analyze structural integrity, aerodynamics and thermal performance directly within NX CAD. Accelerate the validation process and reduce risk during physical testing and certification phases by testing design changes virtually in real-time. By simulating behavior under real-world conditions, your team can detect and resolve issues in the digital space—long before any metal is cut. 

Moreover, NX CAD fosters better collaboration across disciplines, ensuring consistency and traceability throughout the design cycle as mechanical, electrical and systems engineers can work from a unified model. With built-in data continuity, changes are automatically reflected across downstream processes—from manufacturing to maintenance—streamlining the entire lifecycle. 

Ultimately, a digital twin empowers aerospace organizations to innovate faster, reduce development costs and deliver safer, more efficient products to market with confidence, and NX CAD includes unique tools for efficiently creating a comprehensive digital twin.

Bring engineering teams together in a shared environment in NX. Designing an aircraft or a spacecraft isn’t just about engineering—it’s about orchestration. Whether you’re refining the aerodynamics of a next-gen fighter jet or mapping the thermal load paths of a deep-space vehicle, chances are you’re not doing it alone. From propulsion experts to thermal systems engineers to avionics specialists, you all rely on tight collaboration between disciplines that often speak very different technical languages. Without a shared environment, it’s far too easy for your teams to work in silos, miss interdependencies or lose time reconciling different versions of the same system. 

When you can make quick, real-time updates then quickly re-run validation tests or simulations, your teams can catch issues early—before they show up in a physical build or certification review.  NX CAD supports both parametric and direct modeling, which makes it possible for design engineers, systems integrators and analysts to iterate quickly, thus you don't need to wait as long to get design changes back from another team.

Collaborate across the product lifecycle and the supply chain with NX CAD and the Siemens Xcelerator platform. Modern aerospace programs don’t exist in one building. Your flight controls might be developed in Germany, your composite fuselage in Wichita and your propulsion module outsourced to a partner in Asia. NX CAD, especially when seamlessly paired with Teamcenter, supports secure data sharing and version control across all these boundaries. With NX and Teamcenter, you team can stay aligned with configuration standards, regulatory requirements and design targets—even if you've never met face-to-face.

NX X, the SaaS deployment of NX CAD, includes built-in data management, making it even easier to collaborate than ever before within and across different disciplines.

Minimize human input for repetitive design tasks with AI-enabled tools in NX CAD design automation tools. NX CAD includes rules-based design tools, templates, equation-driven modeling and more. With these tools, you could codify expert practices, ensuring consistency and reducing dependency on manual checks. Or, you can apply standard design rules, enforce engineering constraints and even suggest corrections in real-time. For instance, in structural design, NX CAD can automatically identify areas where geometry could be simplified, reducing weight without compromising strength.

Shorten the design cycle and improve performance outcomes by generating optimal shapes without manually modeling parts. With AI-enabled generative design in NX CAD, simply set performance parameters—such as stress limits, material types, and manufacturing methods—and explore the design options. NX CAD explores thousands of design possibilities that would be nearly impossible to evaluate manually. The result? Lighter, stronger and more efficient parts that are tailor-made for aerospace products, whether it’s a satellite mount or a turbine bracket.

With AI in NX CAD, not only are you speeding things up, but you can reshape what is possible in aerospace engineering. Transform design from a hands-on drafting process into a guided, semi-automated data-informed workflow so that you can focus on creative problem-solving and advanced performance goals.

Evaluate materials not only for performance, but for their environmental impact over the product lifecycle. By leveraging integrated materials libraries in NX CAD and Siemens' Teamcenter Integration for NX, you can compare recycled or lower-impact materials, simulate long-term behavior and document compliance with sustainability standards such as REACH and RoHS. This allows for more responsible sourcing and long-term efficiency across the supply chain. 

Improve fuel efficiency and reduce emissions by reducing structural weight with NX CAD. With topology optimization and generative design tools, you can explore design options for minimizing material usage while still maintaining safety and strength. You can leverage these tools to identify areas for mass reduction early in the design process—whether it’s for airframes, brackets or satellite components—leading to lower fuel consumption and longer mission ranges.

NX CAD also includes has specialized, industry-leading composite design capabilities for straightforward and economical development of high-performance aerostructures.

Save time, minimize unnecessary resource consumption and increase multidisciplinary collaboration with design reuse tools in NX CAD. Create next-gen propulsion systems by digitally cloning and refining propulsion subsystems from prior projects. Plus, with seamless integration to Simcenter, your teams can simulate thermal loads, airflow dynamics and mechanical stresses early in the process—leading to more efficient, low-emission propulsion designs that support sustainability goals.

Accelerate design validation and ergonomic testing in cockpit and control system development, as immersive CAD tools allow you to test layouts, controls and visual interfaces in virtual prototypes. Instead of waiting months for mockups, you can perform immersive simulations to get immediate feedback from operators.

Create realistic visualizations for design reviews, without relying on expensive physical prototypes as you manage complex builds like fighter jets or missile systems. For next-gen fighter cockpits, you can ensure intuitive control schemes and reduce cognitive load before anything is built. Simulate interactions to identify design flaws early, shorten development cycles and ensure human-centric designs meet both mission and safety requirements.

Visualize internal systems—like avionics bays, hydraulic lines, and access panels—in 3D VR, without disassembly. Optimize serviceability of parts by ensuring critical components are reachable as you design. This minimizes aircraft downtime, improves field readiness, and supports digital twin strategies that track the health of assets throughout their lifecycle—critical for military operations and fleet sustainment.

With immersive technology, technicians can also practice procedures in AR/VR environments, thus reducing training time and avoiding real-world damage.
