Thermo-Mechanical Structural Optimisation of a Chemical Propulsion Satellite Thruster Using Lattice Structures
Abstract
Small satellite space thrusters are designed to provide force for short time periods.• New generation of thrusters will be made with High Entropy Alloy (HEA) materials.• Predicting damage initiation for this kind of metallic structure subjected to thermal shock is of fundamental importance.• The preliminary thermal-stress analysis is mandatory in order to understand the complex failure mechanism of the space thruster.• An optimisation analysis of the material distribution along the combustion chamber thickness can lead to an improvement of the thermal-stress response.
