A new pressure-coupled response function of solid propellants has been theoretically derived by means of a combustion response model basing upon the steady-state burning model of composite solid propellants including those with negative pressure-exponents. In this combustion response model, the burning surface of a given propellant is divided into two parts, namely, one consisting of a region of the AP surface covered by molten binder with the corresponding binder surface and the other...

A new pressure-coupled response function of solid propellants has been theoretically derived by means of a combustion response model basing upon the steady-state burning model of composite solid propellants including those with negative pressure-exponents. In this combustion response model, the burning surface of a given propellant is divided into two parts, namely, one consisting of a region of the AP surface covered by molten binder with the corresponding binder surface and the other consisting of a region of the AP surface uncovered by molten binder with the remaining binder surface. In analyzing the part of AP surface covered by molten binder, the condensed-phase reaction and the opposed gasification of covered AP are considered. For plateau and mesa propellants, the real part of the pressure-coupled response function may be positive. The results calculated by the derived pressure-coupled response function for the S04-5A propellant are in reasonable agreement with the instability behavior observed experimentally. When the greater part of the burning surface is covered with the molten binder, the nonsteady state combustion can also occur. The combustion response model can be used not only to explain the instability behaviors of the plateau and mesa propellants, in contrast to the pressure-coupled response functions presented by previous investigators, but also to show that the steady-state burning model developed for composite solid propellants including those with negative pressure-exponents is reasonable and acceptable.

根据呈正、负压力指数燃速特性的固体推进剂的稳态燃烧模型,导出了一个新的压力响应函数公式,它可用来说明燃速压力指数为零、正、负各类推进剂的压力耦合现象。燃烧中的推进剂被划分为两部份:一部份是由熔化了的粘合剂所覆盖的氧化剂表面与其相对应的粘合剂表面所组成,而另一部份则由未被覆盖的氧化剂表面同剩下的粘合剂表面组成。与以往的各类模型不同,在上述的前一部份燃烧表面的燃烧中,考虑了氧化剂在熔化粘合剂覆盖的条件下存在着反向气化和凝相反应,故使所得的压力响应函数的实部在推进剂稳态燃速的压力指数为零或负值时也可为正值。利用所获得的压力响应函数的表达式对试验用推进剂(S04-5A)作了定量计算,计算结果满意地说明了,负压力指数推进剂在氧化剂被熔化粘合剂大面积复盖时也存在不稳定燃烧的现象。这不仅克服了以往所有压力响应函数表达式均难以用于负压力指数推进剂的缺陷,而且也从一个侧面反映了呈正、负压力指数燃速特性的固体推进剂稳态燃烧模型的正确性。

The BDP steady burning model is revised in this paper and the revised BDP model is used in the prediction of steady burning rates of composite propellants. Based on the revised BDP model and turbulant flow theory, a model for erosive burning is proposed. When the propellant compositions, chamber pressure and gas-dynamic conditions are given, these models can be used in the prediction of steady state and erosive burning rates.

本文对BDP稳态燃烧模型进行了必要修正,并用于预估推进剂稳态燃速。在此基础上,考虑湍流引起的火焰区输运系数的增强,建立了侵蚀燃烧模型。给出推进剂配方、燃烧室压力和气动条件的情况下,可用本文提出的模型比较准确地预估稳态燃速和有侵蚀燃速。

Despite the fact that various types of FCC regenerator are in commercial use, it is belived that they can be summed up into two typical regeneration processes: backmixing regeneration in fluidized bed and coke-burning regeneration under near gas transfer condition with the addition of mixing under various circumstances. A generalized model based on this concept is developed which consists three blocks, i.e. back-mixing model, coke burning model and a mix block. This modular general model is very simple and practical in use.The precision of this model is greater than that of a special purpose model.Its overall average relative error is about 10%.
