摘要:
为了给埋头弹火炮可燃导向管的材料选择和结构尺寸设计提供依据,该文研究了埋头弹在膛内的运动过程和药室中的流场变化规律。考虑到埋头弹火炮药室内具有显著的两维流动特性,该文应用两相流体力学理论和计算流体动力学技术,建立了药室内的非稳态轴对称两维多相流和身管内非稳态一维两相流相结合的模型,并进行了数值模拟。计算结果表明要使弹丸嵌入膛线之前导向管不发生破裂,导向管的强度应达到5 MPa以上。
Abstract:
To provide evidence for designing the material and the structure of the control tube of cased telescoped ammunition(CTA) gun,the movement of CTA in bore and the change of flow field in chamber are studied.Considering the conspicuous two-dimensional characteristics in the chamber of CTA gun,a mathematical model composed of unstable axis-symmetrical two-dimensional multiphase flow interior ballistic model and one-dimensional two-phase flow interior ballistic model is established and simulated by using the two-phase flow method and computational fluid dynamics(CFD) technology.The numerical results show that the strength of control tube must be up to 5 MPa if it is required not to be damaged before projectiles engrave chamber lines.
