Learjets have been garnering attention for decades, and Bombardier Aerospace’s new Learjet 85 business jet is no different in that regard. It is novel in a number of ways, however, including the engineering workflow in which it was designed and developed.
Bombardier Aerospace engineers employed a complete digital development process for the Learjet 85 aircraft’s electrical distribution system. In fact, the electrical wiring system development process on the Learjet 85 benefitted from the Mentor Graphics Capital product family.
Specifically, Bombardier Aerospace used Capital Logic, Capital HarnessXC, and Capital FormboardXC software, supplemented by Capital’s CATIA V5 MCAD integration applications. Mentor Graphics Corp.’s Capital product, an advanced software suite for the electrical systems and wire harness domain, has been used by leading aerospace original equipment manufacturers (OEMs).
The Capital product delivers a number of benefits; for example, design data was shared between all the tools, enabling digital continuity throughout the development process. Applications in the Capital software also: helped address electrical systems definition and integration, incorporated with mechanical CAD systems, and culminated with products that address harness planning and manufacturing tasks.
Data verification occurs throughout the process with the Capital product. Constant design verification helps engineers ensure that the manufactured wire harnesses meet the design intent. It also enables process and quality improvement objectives, including adherence to the FAA and Canadian Transportation Agency’s Federal Aviation Regulations (FAR) Part 25 Electrical Wiring Interconnection System (EWIS) mandate for the certification of new civil aircraft. In fact, EWIS wire routing constraints defined early in the Capital environment are maintained throughout the workflow and ensure that the as-built wire routing meets the EWIS mandate objectives.
This military and aerospace (mil/aero) geek is always excited to hear real-world digital and platform-level engineering design successes.
