Chemical alleviation for improvement of reentry communication by solid ablation and liquid injection has been a practical way. The mechanism of chemical alleviation and the method of experimental studies of simulation in an arc tunnel are disscussed in this paper. Studies have been performed in the H11DF arc tunnel by diagnostic methods of heat-protection material upon the electron concentration and the microwave transmission, and the injection of different electrophilic reagents upon the electron concentration have been determined. This has provided basis for selection heat-protection materials and identifying their properties.

化学减轻改善再入通讯是现实可行的技术途径,它是通过固体烧蚀和液体喷射的方法实现的。本文探讨化学减轻的机理和利用电弧风洞进行模拟实验研究的方法。实验是在H11DF电弧风洞中完成的,采用微波和探针两种诊断手段。通过大量实验确定了防热材料的烧蚀产物对流场电子密度和对电波传输的影响,以及喷射备种亲电子液体对流场电子密度的影响,为筛选防热材料及鉴定其性能提供依据。

Jet exhaust of solid rocket motor has serious effect on heat protection material. Especially, metal oxide particle play an important role in the erosion of material Surface.

固体火箭发动机排出的高温、高速燃气对热防护材料有很大的侵蚀作用,特别是燃气中的氧化铝粒子对材料的侵蚀起主要作用。为此,本文对粒子侵蚀问题做了理论分析和实验研究;提供了一个用以计算粒子侵蚀速度的方法和公式。最后的算例表明,此方法可行,并具有足够的精度。

The ablative properties of B-phenolic resin, Mo-phenolic resin, P-phenolic resin, polyaralkylphenol resin and phenol triazine resin(PT resin) are briefly introduced. At the same time, the ablative properties of the phenolic resins modified with ary-kte, alkylate and DA modifiers and the main properties of benzoxazine resin and new phenolic resins S - 157 & S - 158 are introduced. Meanwhile, the other modification research, such as phosphorus-cyanogen chloride modified phenolic resin, is also introduced. It is...

The ablative properties of B-phenolic resin, Mo-phenolic resin, P-phenolic resin, polyaralkylphenol resin and phenol triazine resin(PT resin) are briefly introduced. At the same time, the ablative properties of the phenolic resins modified with ary-kte, alkylate and DA modifiers and the main properties of benzoxazine resin and new phenolic resins S - 157 & S - 158 are introduced. Meanwhile, the other modification research, such as phosphorus-cyanogen chloride modified phenolic resin, is also introduced. It is pointed out that the modified phenolic resin is still a low-cost heat protection material to be used in the ordinary arms in the future.

简单介绍了在酚醛树脂烧蚀性能的改进研究中硼酚醛、钼酚醛、磷酚醛、聚酚醚和酚三嗪树脂的烧蚀性能,也介绍了使用芳基酚、烷基酚与DA改性剂改进的酚醛树脂的烧蚀性能,以及开环聚合酚醛树脂和新型酚醛树脂S-157与S-158的主要性能。同时介绍了氯化磷腈改性酚醛树脂和提高酚醛树脂成炭率的其它改性研究。指出了改性酚醛树脂仍然是今后常规武器系统使用的一种低成本热防护材料的树脂基体。
