Design of Combustion Science Experimental System for China Space Station

In order to conduct the microgravity combustion experiments in China Manned Space Station, it is necessary to establish an onboard combustion science experiment system. With the experimental study of microgravity combustion, it is beneficial to expand the depth and breadth of combustion research and promote the development of combustion science. According to the functions to be realized and the requirements of combustion experiments, the design and analysis of the experimental system for combustion science rack are carried out. The combustion experiment system consists of eight subsystems, which is a comprehensive experiment system that is suitable for combustion experiments with gas, liquid and solid fuels, respectively. In consideration of the strength design requirements, after the completion of the scheme design, the finite element analysis of the system is carried out, and the mechanical environment experiment is completed with the developed structural setup. The experimental and analytical results show that the design can meet the requirements of the environment simulation experimental outline, and is reasonable and feasible for space experiments.
