Integrating Finite Element Analysis into the Spacecraft Thermal Analysis Process
Young Graduate Trainee (YGT) Project: May 2004 – April 2005
There are many steps in the spacecraft thermal analysis process such as conductor generation, pre/post-processing and mapping of temperatures to a structural model. This report seeks to identify some of the key steps in this process and to assess where the use of FEA may be beneficial. Furthermore, in order to aid the integration of FEA into the thermal analysis process, several tools have been developed and these will be presented within the report. The key objectives of the investigation are:
- To consider the different steps and processes involved in spacecraft thermal analysis
- To asses which steps in the process could benefit from the use of FEA
- To investigate where it is possible to use TLP and FEA methods together and how it is possible to map between the methods
- To elucidate these issues and provide quantitative data by running some test cases
- Focus on development of general methodologies rather than creating a single specific tool
- Development should be as tool independent as possible and use neutral formats if feasible
- Where possible, existing, trusted, software tools should be used
- Development should act as a first step towards integrating FEA, allowing users to experiment with minimum financial investment or time commitment
