Kawasaki Heavy Industries Introduces Zuken’s E3.series and DS-2 to Aircraft Development for the Japan Ministry of Defense

Reading time ( words)

Kawasaki Heavy Industries, Ltd. has introduced the E3.series electrical control and wire harness design system and the DS-E3 product data management system (PDM) from Zuken Inc. for the electrical design of aircraft for the Ministry of Defense of Japan. The software introduction aims to reduce the person-hours required to ensure traceability of wire harnesses by model number as required by aviation industry standards. A model number is a unique number assigned to an aircraft of the same model for identification purposes.

Because an aircraft is built to last for decades, strict quality control and traceability are essential throughout the lifecycle of the aircraft to ensure high standards of safety. As the aircraft bodies developed by Kawasaki Heavy Industries for the Ministry of Defense of Japan have an extremely long product lifecycle of 50 years, a considerable number of person-hours was required to understand model-specific design and manufacturing details and subsequent changes to equipment and wire harnesses across their maintenance lifecycle.

To address these issues, Kawasaki Heavy Industries introduced Zuken’s E3.series and DS-2 software suites, which are widely adopted in the aviation industry. The new procedure automates compliant management of design data and the release of drawings at each phase of the design and manufacturing processes, thereby reducing manual overhead and enabling traceability in the design and manufacturing of electrical wire harnesses. Overall, this new design and manufacturing procedure has significantly reduced the hours required to create data for the test of 40,000 aircraft wire harnesses, which previously required an effort of 12 person-months.

Commenting on the benefits of Zuken’s E3.series and DS-2 software, Toshinori Kakui, Senior Staff in the Electrical Systems Engineering Department of Kawasaki Heavy Industries Aerospace Division, said, “Zuken’s E3.series and DS-2 software improved design operations have accelerated the delivery of drawings and shortened manufacturing lead times.”

Knowledge transfer, especially from the “graying-out” experienced technical workers in our industry, is a complex, difficult family of problems. It differs wildly between companies, and even within divisions of the same company. One of the biggest barriers is the full manufacturing schedules in North American electronics companies that don’t leave any slack time—and the 40-hour work week is a complete fantasy for many.

Buy new or make do? It’s an age-old debate for manufacturers who are trying to decide how best to manage machine assets inside their manufacturing facilities. New machines are expensive, but so is operating existing machines at a comparative deficit.

It’s easy to frame all our supply chain woes around the COVID-19 pandemic. However, at Screaming Circuits, we started receiving dire warnings about component shortages in early 2018. At that time, we were told that the supply upheaval could last years and that we should expect it to get much worse before it got better. Now, four years later, I would say those warnings nailed it.
