Objectives
| Alphabus, built jointly by ALCATEL SPACE and EADS ASTRIUM, will cover a payload power range from 12 to 18 kW corresponding to a solar array power between 15 and 25 kW. . Its main objective is to develop a high-performing satellite platform family in this enhanced power range, which will integrate most advanced equipments from world class suppliers. |
Several pre-developments are currently being kicked-off, in order to develop advanced technologies in critical areas. In particular, thermal analysis software tools used to support the development of these large platforms must include some key features as described hereafter. These will be developed within a short time frame (14 months):
- Capability for both ALCATEL SPACE and EADS ASTRIUM to perform alternatively the AlphaBus system thermal analyses in the different development phases.
- Exchange of experience in telecommunication spacecraft thermal control analysis techniques and, where possible, common development of modules which are not available on a commercial basis e.g two phase and single phase fluid loops modules.
- Improvement of overall productivity thanks to better data interfaces between tools.
As required by ESA and the Alphabus Project, ALCATEL SPACE and EADS ASTRIUM thermal software shall use ESATAN as the reference solver.
Challenges
Not Applicable.
