    Electrical Wiring Design and Development Studies of a Communication Satellite
    (Düzce Üniversitesi, 2024) Keskin, Emre; Kara, Onur; Özbek, Sabri; Aydin, Samet Emre; Demirdağ, Serdar
    In this study, information about a harness subsystem, connects signals and electrical power with 25 km of wiring and 1100 connectors, which is designed and developed for the communication satellite consisting of communication module and service module is given. Harness 3-dimensional layout is developed in NX computer aided design (CAD) software, providing key design features i.e., minimum bend radius, easy installation and stress relief. A variety of design solutions are implemented in order to achieve electromagnetic compatible electrical wiring interconnecting system (EWIS). Possible electromagnetic interference sources such as wire-to-wire coupling, electromagnetic field-to-wire coupling and structural current-to-wire coupling are eliminated. The electrical interfaces are developed in three phases: avionics architecture, pin to pin and connectivity design. As intermediate connectors are implemented to harness to provide physical separation which support system level modular design approach, also safe/arm connectors and umbilical connectors are implemented to satisfy functional and operational needs. “On panel” and “in panel” type connector brackets are developed for plug and receptacle connector mating. Harness components are chosen based on thermal ambient conditions and wires are sized according to current derating requirements.
