摘要/Abstract

摘要：

针对微小型弹药布局设计的现有约束问题，提出了一种新的微小型弹药布局优化方案，基于正常式布局的结构，建立弹药的三维气动模型，对微小型弹药进行流体力学仿真，研究了弹翼尺寸对弹体静稳定性的影响。为验证设计方案的可行性，利用不同的飞行条件进行模拟气动计算，得到微小型弹药的升力、阻力及俯仰力矩参数，计算了升阻比与可用过载。仿真结果表明：所提微小型弹药气动布局方案满足设计要求，且具有良好气动特性和飞行稳定性，为后续设计提供一定的参考依据。

关键词: 微小型弹药, 正常式布局, 弹翼尺寸, 气动特性, 飞行稳定性

Abstract:

Aiming at the existing constraints of layout design of miniature munition, a new layout optimization scheme is proposed. Based on the normal layout structure, a three-dimensional aerodynamic model of munition is established, and the aerodynamic hydrodynamics simulation of miniature munition is carried out, and the influence of wing size on static stability of munition is studied. To verify the feasibility of the design scheme, the aerodynamic simulation calculation is carried out, and the lift, drag and pitching moment parameters of miniature munition are obtained through simulated aerodynamic calculation under different flight conditions, and the lift-drag ratio and available overload are calculated. The simulation results show that the proposed aerodynamic layout scheme of miniature munition can meet the design requirements, and has good aerodynamic characteristics and flight stability, which can be a reference to the subsequent design.

Key words: miniature munition, normal layout, wing size, aerodynamic characteristic, flight stability
