Evaluation of missile electromagnetic launch system based on effectiveness

Abstract

To solve the problems of strong infrared radiation, poor continuous combat capability of the system, serious ablation of the launching device, and environmental pollution of the existing missile launching system, electromagnetic launch system (EMLS) has been studied for missile launch system. Combining the situation that the current research on missile electromagnetic launch system (MEMLS) mainly focuses on the key technical points and the deficiencies in the previous research on MEMLS, this paper establishes an effectiveness prediction model based on GRA-PCA-LSSVM, and discusses the investment efficiency of the system based on DEA. The experimental results prove that the established model is reasonable, effective and superior, and provides a reference for the further improvement and development of MEMLS.

Dynamic Simulation Research of Flexible Airbag Ejection System Based on Corpuscular Method

“…Meng et al [5] studied the kinematic characteristics and structural safety of multi-stage piston cylinder launcher by theoretical analysis and numerical simulation, and revealed the influence law of factors such as structural characteristic deviation and gas dynamic deviation on the missile off-orbit attitude. Lin et al [6] elaborated the basic principles of electromagnetic ejection technology, established the motion model of electromagnetic ejection type missile launch, completed the simulation calculation, and designed the electromagnetic ejection system. Although the ejection devices based on the abovementioned power sources have many advantages, they also have their shortcomings.…”
