The Capital Load Analyzer software product helps simplify aircraft electrical design compliance and certification. The new Capital Load Analyzer is the industry’s first electrical systems technology that leverages automation and digital data continuity to facilitate regulatory compliance.
Current methods for verification and analysis rely on fragmented data and are typically 
conducted manually using drawings and spreadsheets once the major electrical design work is complete. Uncovering problems during this late program phase forces costly design iterations and missed critical milestones, such as Customer Acceptance and Type Certification, impacting aircraft revenue recognition.
To mitigate such risks, the new Capital Load Analyzer product draws upon the electrical digital twin, generated from the overall power system and subsystems design, to predict the aircraft’s electrical power demand. The digital twin, native to the Capital product, is an accurate, up-to-date version of the electrical system as it evolves during the development process. The electrical digital twin provides an automated view of the entire power system, enabling engineers to design for compliance from the beginning of the project. Analysis and simulation are performed using primary design data instead of using traditional disconnected approaches. Rules-based checking and analysis helps enable accurate and complete verification for aircraft power system efficiency for each flight phase – even under load shedding for emergency conditions.
Capital Load Analyzer software automatically extracts all electrical load analysis data into the user’s own reporting template for report generation. This technology pulls data directly from the digital twin so the user can see the impact of design changes at any time and at any stage of the design process. The ability to quickly generate real-time reports enables users to monitor design tasks and identify potential issues early in the design process, thereby mitigating program risk. The Capital Load Analyzer product reports compliance analysis results for each design configuration and variant.
“Capital Load Analyzer is a true electrical collaboration platform that provides the digital continuity required across a broad range of critical tasks for electrical systems compliance and certification,” stated Martin O’Brien, senior vice president, Integrated Electrical Systems, Siemens Digital Industries Software. “Capital’s digital thread allows aerospace electrical system designers to deploy an automated design-for-compliance methodology with greater efficiency, improved product quality and a competitive advantage.“
Siemens is further extending the Capital product line to include two additional technologies. A new wire-derating product optimizes the aircraft’s wire sizes to reduce weight while maintaining integrity against hazards, such as over-heating. And the new 3D signal separation tool evaluates the electrical design against safety-critical design considerations, such as power routing requirements and harness spacing for redundant systems. These products ship in the second half of 2019.
