摘要
为了满足二维弹道修正组件小型化设计要求,设计了3种二维弹道修正组件模型,应用Solid Works软件和ICEM软件分别建立3种修正组件的实体模型和网格模型,并利用Fluent软件进行气动特性数值计算,将计算结果进行对比分析,得出不同修正组件模型参数对气动特性的影响。研究结果表明,修正组件尺寸的减小会增大阻力系数;舵片形状和尺寸对阻力系数和升力系数影响较小,但是对滚转力矩系数影响较大,矩形结构的舵片对舵片周围气动特性会产生不利影响;在满足修正要求的前提下,可以适当缩小舵片面积来降低舵机控制难度,提升飞行稳定性。
In order to meet the design requirements of two-dimensional trajectory correction fuseminiaturization,three models of two-dimensional trajectory correction component are designed in thispaper.Solid models and mesh modes of two-dimensional trajectory correction fuse are established bySolidWorks and ICEM software.By using Fluent software,the aerodynamic characteristics values ofdifferent correction component models are gained.By comparing the aerodynamic characteristics valuesof the three models,the influence of different correction component models on aerodynamiccharacteristics is obtained.The result shows reduce the length of correction component will increase thedrag coefficient.The rudders'shape and size have little effect on lift and drag coefficient while havelarger effect on roll damping moment coefficient.Under the conditions of meeting the correctionrequirement,the area of rudder can be appropriately decreased to reduce the difficulty of steeringcontrol and improve the flight stability.
