美苏两个超级大国为了推行其核垄断和核诈讹政策,在弹道式导弹上互相进行竞争,他们为了提高导弹的生存能力,而发展了多弹头、机动飞行等技术。弹头在再入过程中,严重变钝会增加阻力,降低再入特性;过度烧蚀会影响到飞行器的稳定性;端头不对称烧蚀会引起转向力矩而导致攻角增大等,这些情况对再入飞行器精确度和生存能力有决定性的影响,因此,弹头防热材料是他们研究的重点之一。毛主席教导我们:“知己知彼,才能百战百胜”。关于弹头材料方面苏修十分保密,因此本文的目的在于初步探讨美帝石墨材料在再入弹头上应用进入了什么状态?石墨的应用研究重点是什么?代表性石墨的特性及改进块石墨材料的途径如何?由于查阅文献有限,水平不高,错误之处请指正。
To promote their nuclear monopoly and nuclear fraud policy, the two superpowers of the United States and the Soviet Union compete with each other on ballistic missiles and have developed technologies such as multi-warheads and maneuvers in order to improve the viability of missiles. In the process of reentry, severe bluntness will increase the resistance and reduce the reentry characteristics; excessive ablation will affect the stability of the aircraft; asymmetric ablation of the tip will cause the steering torque to increase and the angle of attack will increase, etc. Which has a decisive impact on the accuracy and viability of reentry vehicles. Therefore, warhead thermal protection materials are one of the focuses of their research. Chairman Mao taught us: “Know thyself and know each other, to victorious.” The purpose of this paper is to discuss briefly what state of the U. S. graphite material has been applied to the reentry warhead. What is the focus of the application of graphite? The characteristics of the representative graphite and the improvement of the graphite material Ways? Because access to literature is limited, the level is not high, please correct me wrong.
