Aerospace wiring harness or cable assembly is a term that refers to the collection of wires, cables, connectors, terminals, and other components that are used to transmit electrical signals and power in various aerospace systems, such as airframe, engine, avionics, landing gear, etc. Aerospace wiring harness or cable assembly is designed to meet the high standards and requirements of the aerospace industry, such as durability, reliability, performance, safety, and weight reduction.

The Design and Development

•  Requirements analysis: This involves defining the functional and performance specifications of the wiring harness or cable assembly, such as the electrical, mechanical, thermal, and environmental requirements, as well as the safety and regulatory standards and certifications.

•  Conceptual design: This involves creating the initial layout and configuration of the wiring harness or cable assembly, such as the routing, placement, and protection of the wires and cables, and the selection and arrangement of the connectors, terminals, and accessories.

•  Detailed design: This involves refining and finalizing the design of the wiring harness or cable assembly, such as the material, size, shape, color, and properties of the wires and cables, and the type, size, shape, and properties of the connectors, terminals, and accessories.

•  Simulation and analysis: This involves using computer-aided design (CAD) and simulation tools to model and test the wiring harness or cable assembly, such as the electrical, mechanical, thermal, and electromagnetic behavior and performance, and the compatibility and interference with other systems and components.

•  Prototyping and validation: This involves producing and verifying the physical prototype of the wiring harness or cable assembly, such as the fabrication, assembly, and installation of the wires, cables, connectors, terminals, and accessories, and the measurement and evaluation of the functionality and integrity of the wiring system.

•  Production and delivery: This involves manufacturing and supplying the final product of the wiring harness or cable assembly, such as the mass production, quality control, and quality assurance of the wires, cables, connectors, terminals, and accessories, and the packaging, shipping, and delivery of the wiring system.

The Manufacturing and Installation

•  Manufacturing: This involves the production of the wires, cables, connectors, terminals, and other components that make up the wiring harness or cable assembly. It requires the use of advanced technologies, such as automated cutting, stripping, crimping, soldering, molding, etc., that can ensure high quality and efficiency. It also requires the adherence to the standards and specifications of the aerospace industry, such as SAE-AS50881, MIL-STD-1553, etc., that define the design, performance, and testing requirements of the wiring harness or cable assembly.

•  Installation: This involves the assembly and integration of the wiring harness or cable assembly into the aerospace system, such as airframe, engine, avionics, landing gear, etc. It requires the use of various methods, such as routing, clamping, tying, lacing, etc., that can ensure proper placement and protection of the wiring harness or cable assembly. It also requires the compliance with the installation instructions and drawings of the aerospace system, as well as the inspection and verification of the wiring harness or cable assembly functionality and integrity.
