Abstract
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.
