Abstract
This article describes in detail principles of manufacturing of DC on-board harness for spacecraft based on a new 3D design technology. This technology puts together all activities of on-board harness production, starting from electrical design and up to the final product readiness. Based on the analysis performed we proposed: necessary software, methods of wires and connector contacts connection, applicable wires and connectors available in Russian and European markets, shielding and insulating materials, test methods. The article discusses benefits of lightweight supply buses technology implementation (as compared to bundle of wires), which are: mass reduction, electrical performances stability improvement, lesser capacity between supply lines, better interference immunity, better thermal performances.
Highlights
Spacecraft (SC) – is a complex technological device comprising many components and systems
SC is composed of two major modules: payload module and service module
The task of ensuring correct operation of a satellite in orbit is accomplished by connecting all units into an integrated electro technical system, and this requires a transmission medium between payload module equipment and service module
Summary
Spacecraft (SC) – is a complex technological device comprising many components and systems. SC is composed of two major modules: payload module and service module. Service module ensures nominal operation of all service equipment of a SC in a space orbit.
