In order to reduce the weight of the missile launching system and reduce the cost of missile launching, a flexible airbag ejection system was researched to achieve work on the missile. Through a combination of theoretical analysis, experimental verification and numerical calculation, the working mechanism and ejection performance of the flexible airbag ejection system are studied. The results show that the results of calculating the deployment process of the flexible airbag by the corpuscular method are in good agreement with the experimental measurement results, and the error does not exceed 1.04%, which verifies the accuracy of the calculation of the deployment of the flexible airbag by the corpuscular method; the ejection performance and ejection working medium of the flexible airbag ejection system The type, temperature, range and area of the flexible airbag are related to other factors. In the study of the ejection working fluid and the structural parameters of the flexible airbag, it is found that the smaller the molar mass of the ejection working fluid and the higher the temperature, the better the ejection performance of the flexible airbag ejection system; When the action area is the same, the larger the aspect ratio of the flexible airbag, the better the ejection performance of the flexible airbag ejection system; When the operating distance is the same, the smaller the aspect ratio of the flexible airbag, the better the ejection performance of the flexible airbag ejection system, and the greater the kinetic energy obtained by the missile.
