摘要：
The working process of cooling inerting system was designed and the mathematical model of cooling inerting under ground state was established.Moreover, the relationship between the volume concentration of fuel vapor, the temperature of fuel and gas phase space and the cooling capacity with time was solved by Modelica software.In addition, the influence of several key parameters on the inerting effect was studied.The results showed that with the increase of pumping flow and the decrease of evaporation temperature, the gas phase space fuel vapor volume concentration became lower, the gas phase space temperature declined, the cooling inerting time was shorter, and the inerting effect became better.With the enlargement of internal heat source, it's more difficult to achieve cooling inerting.Although the internal heat source has a bad effect on cooling inerting, cooling inerting is a viable alternative to tank inerting. © 2021, Editorial Department of Journal of Aerospace Power.
