Research on Inflation Pressure Stabilization/Maintenance of Gas Generator for Mars Lander Airbag

Pressure stabilization parameters of gas generator in cold and normal environments were calculated.Convective heat transfer both inside and outside the airbag,molecular gas radiation heat transfer,and water vapor phase-change heat transfer a chiefly researched in this paper.The relationships of gas temperature,mass of exhaust gas and gas generator mass flow rate with time changing has been obtained.The analysis can provide the data to help project design.
