Title The Reversal Design of 57mm Airborne Rocket Launcher

Abstract Airborne launcher is important in our weapon system for a long time. By surveying and mapping the 57mm airborne rocket launching system, and using UG software ,we model the structure of the rocket launcher. In the process of modeling, according to the professional knowledge of the students in the three years of study, the most important work is the design of the locking mechanism. After the completion of the design, we use ABAQUS finite element analysis software to check the directional device and locking mechanism, analysis rocket in the tube motion, the influence of gas jet of directional device, and the reliability of locking mechanism when a aircraft under the condition of overload. Through the work above, we can make students understand how to design a airborne rocket and how the rocket works. By understanding the past aircraft rocket launcher, analyzing their structures ,we can learn the active airborne rocket much easily. Comparing the two above, we can understand the direction of airborne rocket development and inevitability. Having a good wish to the development direction of future airborne weapon.
