Multiphysics-Based Study of Thermal Temperature Rise of Aircraft Wiring Harness †

The wide application of all-electric aircraft and multi-electric technology has made the design of aircraft EWIS more and more complex, and the integration of wiring harnesses is becoming higher and higher. Aircraft wiring harness thermal temperature rise design is the key technology of aircraft EWIS design, which directly affects the safety, reliability and economy of aircraft EWIS design. Based on the multiphysics research on the thermal temperature rise of the aircraft wiring harness, it is found that there is a large difference between the thermal temperature rise of the wiring harness in the exposed area of the aircraft and the airtight area, and the optimization of the wire harness wire can realize the weight and cost reduction design of the wire harness for these differences and provide aircraft economy under the premise of ensuring the safety and reliability of the aircraft.
