|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):
As required by ESA and the Alphabus Project, ALCATEL SPACE and EADS ASTRIUM thermal software shall use ESATAN as the reference solver.
A brainstorming between ALCATEL SPACE, EADS ASTRIUM, CNES and ESA allowed to define a work strategy for this pre-development taking into account that tools developed by each of the two prime contractors is fully part of their own know how and analysis process. The thermal analysis software pre-development philosophy is then the following:
- to ensure compatibility and standard data exchange solutions for existing modules, i.e. radiative modeling software, panels conductive modeling tools and solvers,
- to develop common modules for the system thermal modeling of fluid loops.
The expected main benefits are to develop key functionality required by ALCATEL SPACE and EADS ASTRIUM to jointly develop the Thermal Control System of Large Platform Missions and to improve the overall efficiency of the collaborative design process.
The study includes the following work packages:
Package 1 :
PACKAGE 2 :
The deliverables are the following:
