- Abstract
Part of the Stuttgarter Small Satellite Programme at the Institute of Space Systems of the University of Stuttgart, is the Lunar Mission BW1, a lunar small satellite mission. This probe will be powered by an electric propulsion system, which is also being developed at the Institute of Space Systems.
As a first step within this paper, the specification of a satellite structure for the Lunar Mission BW1 is compiled and following sub-functions are being derived. By the method of the Morphologic Box, suitable solutions for the sub-functions are combined, to generate first structure concepts. By a rough estimation, these options are being determined, which will be considered in the following examination.
After identifying all prospective systems, which are planned to be integrated in the probe, the four most promising structure configurations are built as CAD models, for carrying out assembly analyses. Due to the fact, that the Lunar Mission BW1 is designed as a technology demonstrator for the electric propulsion system, options of the propulsion module with additional thrusters are of particular interest. The CAD analyses are followed by several finite element analyses of the structure configurations, which gain information about their stiffness and their mass. Ensuing, all structure variants are evaluated with the aid of a target value analysis. As a result of the target value analysis, two structure concepts turn out to be the most promising.
At the moment these two structure concepts are being enhanced to get more detailed information on their mechanical properties and their capability. The detailed data helps to optimise the satellite structure and so to reduce its weight. This paper will show the results of the concept study for the Lunar Mission BW1 as well as the ongoing activities. It presents a systematic method how the structure of a lunar satellite was developed and shows first results of a possible spacecraft structure for the Lunar Mission BW1.
