Design And Simulation Analysis Of Stone Skipping Composite Material Aircraft

Currently, anti-ship missile defense technology for increasingly high levels, there is an urgent need to improve their ballistic anti-ship missiles and stealth technology orbit technology to increase the naval defense penetration capabilities.Based on the principle of ballistic orbit naught technology transformation provides a new solution for track anti-ship missiles.The main topic is the lack of features and the characteristics and technologies existing flight orbit anti-ship missile, designed to be affixed to the surface of a wave splashing into the water ahead of the aircraft type between the air and water, the two media, the impact force to enter the water the simulation and analysis of checking the strength of aircraft composite structures.In a few months before that where I conducted a lot of research on the following:(1) Design of a type capable of low-flying aircraft splashing into the water, the main design material is epoxy composites specific strength and high modulus carbon fibers are in the air and water between the two media, design carbon fiber composite laminated structure.The maximum flight speed of the aircraft were theoretical calculations, the choice of turbofan engine to provide forward momentum for the aircraft, in order to avoid hitting the water in the process of rolling or tilting the aircraft to generate a set of rotating disk devices increases, both to ensure the aircraft in advance the have plenty of power, but also to ensure its stability in flight and hit the water in the process.(2) UG software in the overall structure of the aircraft has been simplified, including the establishment of a simplified model of the aircraft, the overall mathematical model of water and air in HyperMesh, select the LS-DYNA software ALE method for aircraft hit the water a dynamic process simulation analysis, has been subjected to pressure in the aircraft splashing into the water during the peak impact pressure curve and bottom load distribution.(3) Obtained by the simulation based on the aircraft's maximum impact pressure and the bottom of the pressure distribution, with a housing unit to establish the overall finite element model of aircraft composite structures, according to the results of maximum stress LS-DYNA program was to determine the overall composite aircraft structural strength requirements of the material. According to the calculation results and the analysis, to prevent damage to the vehicle side recommendations.
