摘要:
在红外干扰弹自身特性研究领域中，与其相对静态的辐射特性研究相比，其复杂多变的动态气动特性研究对于实战应用显得尤为重要。为此，本文针对红外干扰弹多元气动特性影响，利用空气动力学原理及大气模型，系统分析了红外干扰弹的飞行速度与马赫数之间的紧密关系，进而高效模拟了红外干扰弹气动模型在三维立体空间中的作用效果。通过VC++.net及OpenGL开发工具对干扰弹的实际弹道模型进行综合模拟仿真设计实验，将红外干扰弹的气动特性进行自适应调节，基本达到了预期的改进目标，进而为红外干扰弹改进实战效能提供了有力支撑。
In the research field of the elastic characteristics of infrared decoy, the dynamic aerodynamic characteristics research is particularly important for the practical application of it compared with the relatively static radiation characteristics research. Therefore, considering the influence of the multi dynamic characteristics of infrared decoy and using the principle of aerodynamics and at-mospheric model, we systematically analyzed the close relationships among the variation law of gravity attenuation, flight speed and Mach number of the infrared decoy, which effectively simu-lated the trajectory effect of the pneumatic model of the infrared interference missile in three- dimensional space. Using development tools like VC++. Net and OpenGL to do integrated simulation and design experiment on the actual trajectory model of the decoy and adaptively adjust the multiple dynamic characteristics of the decoy basically reaches the expected improvement goal, and further provides a strong support for the improvement of the tactical infrared decoy combat effect.
