Title Micro recoil automatic gun engineering research -launch process modeling and simulation
This article uses each kind in trajectory theory, has conducted the research and the exploration to the micro recoil automatic gun's in trajectory process and the launch performance. The study induced in the classics the trajectory theory, to have no children in the recoil artillery in the trajectory theory as well as the expansion wave artillery the trajectory theory related concept and the research results, based on this established the micro recoil automatic gun's in trajectory mathematics physical model.According to the existing condition, the primary learning mathematical simulation analysis's theoretical knowledge as well as the research technique, have established the micro recoil automatic gun's in trajectory simulated program using matlab, in and before arranged the trajectory procedure first time by the known 122mm artillery's structure data and the powder charge condition (to unlatch) has carried on the confirmation, the simulation result and tallies actually. Using in trajectory procedure which establishes, originates take the known 57mm anti-aircraft artillery's structure data and the explosive propellant as the data, in the other condition invariable situation, has studied the different nozzles throat diameter internal trajectory characteristic influence.In this article the trajectory simulation analysis's attempt to studies to the micro recoil automatic gun in masters the trajectory knowledge as well as mathematical simulation analysis crossing the threshold is skilled very beneficial.
Key word: Micro recoil automatic gun, in trajectory, simulation, artillery
