Simulation and Analysis of Thermal and Dynamic Properties of Rocket-Borne Aerostat During Deployment
Based on the model of the aerostat during ascent,the thermal and dynamic models of the inflatable process of the rocket-borne aerostat were established.A specific example was simulated by Matlab programming,and the altitude,pressure difference,and gas temperature were analyzed in detail.Effects of the delivery height,initial ve-locity and inflation time during the deployment of the system were explored.The results show that the distance be-tween the end of the inflation process and the target height can be reduced by reasonably controlling the above three variables,so as to lower the pressure difference and arrival time,and realize achieving the optimization of the deploy-ment process.The theoretical models and simulation program can provide a reference for the selection of launch pa-rameters of the rocket-borne aerostat.
