摘要/Abstract

摘要： 二维弹道修正引信实现弹道修正的前提是对头部翼面部分转速进行控制。基于155 mm 固定翼双旋弹二维弹道修正引信平台，分别对双旋环境下弹体和翼面的转速特性进行了分析。建立翼面作用下双旋弹丸运动模型，采用计算流体力学软件对二维弹道修正引信进行数值模拟，计算得到了翼面各项气动力参数；通过对二维弹道修正滚转通道动力学方程展开分析，以弹丸和头部翼面部分转动惯量为基础，综合分析了翼面转动惯量、摩擦力矩、翼面滚转阻尼力矩和翼面导转力矩对全弹道转速、落点、横向偏差、攻角的影响；在转速控制基础上对155 mm 固定翼二维弹道修正引信修正能力进行了评估。研究结果表明：二维弹道修正引信导转翼面角度取5.0°~5.5°、修正翼面角度取8°~9°时可以满足控制所需的平衡转速和修正能力要求；双旋转速仿真结果可以反映弹道修正引信、精确制导组件等双旋弹丸的转速特性，为此类双旋弹丸翼面部分设计提供了理论依据。

Abstract: The premise of realizing the trajectory correction of two-dimensional trajectory correction fuze is to control the spin rate of fixed canards. Based on the 155mm fixed-canards projectile with two-dimensional trajectory correction fuze, the spin characteristics of projectile body and canards during dual-spinning are analyzed, respectively. A motion model of dual-spin stabilized projectile under the action of fixed canards is established. The two-dimensional trajectory correction fuze of 155 mm fixed-canard dual-spin projectile is simulated to calculate the aerodynamic parameters of canards by using CFD software. The dynamics equation of rolling channel is analyzed, and the characteristics of whole ballistic spin rate are analyzed from the following aspects: moment of inertia, moment of friction, rolling damping moment, and moment of canard guide roll moment. On the basis of spin rate control, the correction capability of two-dimensional trajectory correction fuze is evaluated. The simulated results show that 5.0-5.5 degrees of the rotating canards and 8-9 degrees of the modified canard can meet the requirement of balancing spin rate and the correction capability for control, and the simulated results of spin rate can represent the rotational speed characteristics of dual-spin-stabilized projectiles with course correction fuze and precision guidance kit.
