Challenges in the Aerospace and Defense Industry

The Aerospace and Defense Industry is expected to experience continued growth in most segments for the foreseeable future. Commercial airlines, in particular, continue to purchase new aircraft to lower the cost-per-seat-mile cost. The challenge today, whether it’s a commercial program or a government contract, is to deliver a product that meets all the technical and performance requirements at cost and on schedule. This challenges OEMs and their suppliers to continuously transform their extended supply chains to optimize total productivity while maintaining a highly dynamic and virtual workforce.

With this in mind, the unique value that as a Siemens Digital Industries Software partner we can provide is the ability to help companies in the Aerospace and Defense Industry to more successfully pursue their projects while containing costs and driving excellence in program execution.

The need to fully understand the manufacturing implications of multiple design alternatives is an important element of program success.

The shift-left strategy

Enabling early involvement of manufacturing engineering in the assessment of design alternatives, accurate planning for on-time project launch and effective communication with the shop floor are all examples of opportunities for companies to shift left the integration of the manufacturing definition in the product development process.

With the shift-left strategy, design teams can evaluate different design alternatives from the beginning. But production scheduling teams can also make production decisions at the same time as the aircraft design evolves. In this way, critical decisions are made collaboratively.

Shift left program decisions are a critical initiative for Aerospace and Defense companies.

The role of Digital Innovation

As the industry recovers after the pandemic, companies in the Aerospace and Defense Industry that focus on Digital Innovation should thrive, according to Deloitte. This will be especially true for those that prioritize greater efficiency in their engineering, manufacturing, and supply chain processes by implementing Digital Thread and Smart Factory solutions.

By investing in digital initiatives across production and the supply network, Aerospace and Defense manufacturers can solve specific challenges such as fluctuating demand. This comprises data capture and analysis across their manufacturing footprint to identify breakpoints and opportunities for improvement.


To achieve program profitability while satisfying demands for more mission capabilities, aerospace companies must turn to a digitalized approach. Digitalization not only allows teams to work in a virtual environment, but introduces a high level of automation across domains and disciplines bringing visibility, insight and traceability to all facets of electrical program and wire system development.

What we offer to the Aerospace and Defense Industry

If major European Aerospace and Defense companies are our customers, there are many good reasons.

An ongoing challenge for these companies, for example, is that they must produce systems that operate in different environments, such as air and land, naval and maritime, space and cyber-space, and of course, each product comes with its own special requirements.

PCB Design and Verification

The products of Aerospace and Defense companies are mainly multi-board projects that include analog and digital programmable devices, with high-speed communication lanes and high-efficiency DC/ DC converters close to analog nets. Their boards are very complex. In designing these complex boards, companies face a spectrum of challenges ranging from ensuring signal and power integrity, to manufacturability, meeting reliability and cost requirements, and up to providing higher functions with increased thermal density successfully. One of the designer’s biggest challenges is the complex routing required for their many high-speed nets to the FPGA.

To address these design challenges and achieve right-the-first-time innovations quickly, they use the tools like Xpedition, PADS Professional, HyperLynx, and Valor NPI.


Siemens' Simcenter software uniquely combines system simulation, 3D CAE, and test to help Aerospace and Defense designers to predict performance across all critical attributes earlier and throughout the entire product lifecycle. By combining physics-based simulations with insights gained from data analytics, Simcenter tools like Flotherm XT and FLOEFD help you optimize the design and deliver innovations faster and with greater confidence.

Electrical System Design

For Electrical Systems, the Capital tool suite from Siemens allows Aerospace and Defense manufacturers to improve response times, introduce new technology and innovation, reduce the cost of documentation and improve affordability up and down the supply chain through repurposing and re-use. Engineering teams reduce the probability of being surprised by unexpected issues during platform integration that could force costly iterations. Capital is the only electrical environment that spans the full electrical system value chain: from electrical system definition, through design, into the manufacture, and finally, to support and maintenance.

Hardware Design

All in-flight hardware (i.e., PLD, FPGA, or ASIC designs) must comply with the DO-254 requirements-driven process-oriented safety standard. Today’s safety-critical FPGA designs are typically verified using only simulation-based directed test verification. These methods must be complemented to adequately verify the near infinite state space of the largest designs. Without better verification, it’s impossible to clearly demonstrate that a safety-critical design is truly robust. Siemens EDA Questa Formal Verification, the market leader in formal model checking, can work with simulation to greatly improve design safety and reliability. In addition, this can provide additional DO-254 credit under the heading of “robustness”.

Smart Manufacturing

With the ability to utilize part manufacturing information from design all the way down to the shop floor, Smart Manufacturing by Siemens enables companies involved in the Aerospace and Defense industry to leverage:

  • Automation to improve repeatability and flexibility and reduce rework and scrap.
  • Multidisciplinary process planning to integrate electronic and mechanical systems and processes to build better quality, more complex products.
  • Advanced manufacturing technologies such as additive and robotics to speed up production and lower weight and material usage.
  • Continuously improve and optimize manufacturing processes through insights from IoT and data analytics.
