Objectives
Improvement of the electrical architecture of the Eurostar 3000 platform:
- Study the benefit of a decentralized TM/TC architecture of the communication module,
- Improve the design and performances of the power distribution function,
- Reduce the schedule and non recurring costs of the harness definition and manufacturing.
Challenges
The Key issues are mainly to improve the power performances and the harness production flow from the customization phase to the manufacturing phase.
Plan
The project was carried out within three years with the following milestones:
| KO | April 2006 |
| BDR | June 2006 |
| MTR | September 2006 |
| FR | May 2009 |

| The RB322 unit is currently used on seven commercial programmes for the implementation of the optimised charge by diversion. | |
- Qualification of the Power chain modifications (HW and SW) for the optimization of the charge by diversion.
The optimised diversion is currently implemented on seven commercial programmes, in production with various configurations:
- Mono Power Supply Regulator (PSR) (1 project)
- Bi PSR (3 projects)
- Bi PSR with plasma propulsion (3 projects)
- Development of a harness mechanical and electrical data base.
