This case study highlights how General Atomics Aeronautical Systems, Inc. (GA-ASI), a leader in unmanned aircraft systems, leveraged Siemens Digital Industries Software’s NX, Simcenter, and Teamcenter to streamline and automate their aircraft design processes. Facing challenges such as manual model creation, siloed engineering workflows, and late-stage design issues, GA-ASI adopted Siemens’ integrated suite to build a model-based, automated design framework. By implementing advanced CAD and CAE tools with a single source of truth, the company accelerated design iterations, minimized repetitive tasks, and increased early-phase design maturity. The result: reduced design time, enhanced collaboration, and optimized data management across disciplines.

  • Accelerated Design: NX and Simcenter reduced conceptual design labor by 90%, enabling faster trade studies and design iterations.
  • Integrated Workflow: A digital thread connected CAD and CAE processes, ensuring model reuse and discipline collaboration.
  • Time Savings: Reduced detailed structural design effort by 25%, cutting delays in technical data package preparation.
  • Automation Benefits: NX Open scripts automated fastener modeling and meshing, minimizing manual input in simulations.
  • Data Centralization: Teamcenter established a unified data source, enhancing version control and cross-team coordination.
  • Design Precision: High surface quality in NX models improved downstream CFD and structural analysis reliability.
  • Expert Support: Siemens offered on-site training, tutorials, and responsive customization to support smooth deployment.
  • Strategic Foundation: GA-ASI standardized NX as their core design platform for all future unmanned aircraft programs.
