[ASR] Calculation of the combustion of APER (updated)
The calculation has been done to get the main parameters for ASR's latest propellant APER, the brief report was written in English for advanced readers who were expected to be skillful and knowledgeable rocket researchers.
本计算实验是对ASR高能固体火箭燃料APER改进型的一次热力学计算，这篇简短的报告用英文写成，以此来避免在翻译过程中的数据缺失。本文针对进阶火箭爱好者和读者。
The formulation recently developed for the APER is tentative and can later include other components such as aluminum and DOS
FORMULATION TESTED: AP 68%
Epoxy Resin 20%
Al 12%
Due to the rapid and imponderable variations of most of systematic parameters, the environmental settings can hardly be predicted, so it will be pleasurable to set a mean value. For instance, the calculation requires chamber pressure which is altering through out the process of working. I chose 1200psi (8.27MPa) as the calculated one just by experience.
The variables or operationg conditions controlled in this calculation are listed below:
Temperature of the Chamber 298K
Chamber Pressure 1200psi
Exhaust Pressure 14.7psi (1 atm)
The result of calculation:

The results also include the relationship between the impulse and the exp ratio
I plotted the graph for the data. The graph indicates that when the exp ratio is between 9 and 12, the impulse gets its maximum value, which is about 257s

The results also include the relationship between the impulse and the exp ratio
I plotted the graph for the data. The graph indicates that when the exp ratio is between 9 and 12, the impulse gets its maximum value, which is about 257s

还是用中文写的比较好，英文看不懂。
曲高和寡。
请论坛里哪位高人翻译一下就好了
另外环氧树脂中的固化剂比例是多少？是否要加入增韧剂等？

别急，我自己会重新写中文版的，这个帖子用英文的主要是我最近时间非常紧，而计算输出的数据全是英文的，来不及翻译了，于是就写英文的。后面我会详细介绍这款软件的应用和相关热力学计算理论，并且写中文教程来解释如何用propep辅助开发新燃料。另外，我已指示ASR电子组的程序员们重新校对propep的数据库，并准备汉化本软件，替换美制单位为国际单位。

能不能发一份GUIPEP到论坛上呢？之前那个根本用不了。
