“…The pressure inside the flexible cylinder is equal everywhere, which is the basic assumption of the controlled volume method [5][6]. Viewing the flexible cylinder volume as a controllable volume, the position, orientation and surface area of the individual flexible cylinder units in each time step at a predefined coordinate system can be derived.…”

Cold ejection is widely used in the realm of ejection, but conventional ejection systems can’t adapt to the modern war due to obvious infrared characteristics and high energy consumption, so new ejection system is desired. This work demonstrates a new way of flexible ejection, which is based on control method and corpuscular Method. Firstly, a finite element model of the flexible cylinder ejection system is established. Then, the corpuscular method is applied to study the influence of length and cross-section diameters of the cylinder on the dynamic of ejection process. It is found that the length of flexible cylinder will prolong the time of ejection from 0.72s to 1.01s with length increase from 7.2m to 10.4m. However, the diameter decreases the ejection time. Meanwhile, the velocity increases from 14.37m/s to 15.46m/s with cross-section diameter of cylinder increases from 0.60m to 0.75m. And the maximum overload is bigger 25.9 % than minimum.

“…Control Volume method is a commonly used method for numerical calculation of airbags, which was proposed by Wang and Nefske in 1988 [7] [8]. The method treats the whole airbag as a controlled volume, and the inflation process of the airbag is an adiabatic process.…”

In order to reduce the weight of the missile launch system and reduce the cost of missile launch, a flexible airbag ejection system is studied to realize the work on the missile. The working mechanism and ejection performance of the flexible airbag ejection system are studied through numerical calculation. The results show that the ejection performance of the flexible airbag ejection system is related to factors such as the type and temperature of the ejection medium. In the study of the ejection medium, it is found that: the smaller the molar mass of the ejection medium and the higher the temperature, the better the ejection performance of the flexible airbag ejection system. The research results can provide an important reference for the design and optimization of the flexible airbag ejection system.
