Space engineering - Thermal analysis handbook

Scope

This handbook is dedicated to the subject of thermal analysis for space applications. Thermal analysis is an important method of verification during the development of space systems. The purpose of this handbook is to provide thermal analysts with practical guidelines which support efficient and high quality thermal modelling and analysis.

Specifically, the handbook aims to improve:
1.the general comprehension of the context, drivers and constraints for thermal analysis campaigns;
2.the general quality of thermal models through the use of a consistent process for thermal modelling;
3.the credibility of thermal model predictions by rigorous verification of model results and outputs;
4.long term maintainability of thermal models via better model management, administration and documentation;
5.the efficiency of inter-organisation collaboration by setting out best practice for model transfer and conversion.

The intended users of the document are people, working in the domain of space systems, who use thermal analysis as part of their work. These users can be in industry, in (inter)national agencies, or in academia. Moreover, the guidelines are designed to be useful to users working on products at every level of a space project - that is to say at system level, sub-system level, unit level etc.

In some cases a guideline could not be globally applicable (for example not relevant for very high temperature applications). In these cases the limitations are explicitly given in the text of the handbook.
