The objective of the project is to choose the insulating and conductive materials, the shapes, the dimensions and the means of interconnection of the Axon' bus bar in order to provide qualified technologies to be integrated in a complete power distribution system on @bus service module.
At right is a brief drawing to show different bars used in their environments.
All bars used in this project are in Aluminium alloy. Referring to Copper conductor the outcome of Aluminium density and conductivity is very good.
The thermal behaviour of bus bas is more efficient than wire strands because of bar construction which allows an excellent thermal conductance between conductor layers and a good thermal emissivity.
Size and shapes standardisation:
The goal is to reduce the number of bar types by standardising them to provide a complete power distribution system which fits to the satellite topology.
The architecture of the system is divided into several devices:
Interconnections: (to interconnect bars together with low contact resistance)
Holding device (to hold bars on satellite walls):
The Axon bus bar has been selected for Alphabus and the predevelopment integrated into the Alphabus development. Qualification is expected to be completed by December 2007.
