摘要自从上世纪60年代起，固体火箭发动机推进剂的研究逐渐从传统的复合双基推进剂过渡到了新型固体推进剂的研究。其中铝冰固体燃料推进剂作为一种新型的推进剂开始成为了研究人员的新研究方向。76959

铝冰固体燃料推进剂是一种采用纳米级铝颗粒作为燃烧剂，低温水作为氧化剂的一种新型高能燃料，具有相比于普通双组元推进剂较高的能量密度。除此之外，铝冰推进剂由于其燃烧生成的产物是铝的氧化物和水，因此铝冰固体推进剂也是一种新型环保型推进剂。

本文主要分为两大部分：第一部分分析了铝冰推进剂组成成分对整体燃烧参数的性能影响。利用热力学计算软件CEA分析了H2O2的添加对铝冰推进剂整体的增促作用并考虑了其含量添加的有效范围，考虑了铝含量添加对整体推进剂性能参数的影响。除此之外分析了不同初始工作压强对铝冰推进剂的燃烧性能的影响。第二部分利用流场仿真软件Fluent来分析铝冰推进剂在不同参数下的燃气射流尾流场，分别考虑了来流马赫数、喷管入口温度、喷管入口压强、喷管入口处成分组成对燃气射流尾流场的影响，并通过分析整理得出相关结论。

Title   Alice propellant thermodynamic calculation and numerical simulation of flow field in Alice rocket engine                                                 

Abstract In force since the 1960s,solid propellant rocket motors gradual transition from the traditional composite double base propellant to research new solid propellant。 Wherein Alice as a new solid fuel propellant propellant started to become a new research direction of researchers。

Alice solid fuel propellant is a nanoscale Aluminum particles as a combustion agent, temperature water as an oxidizing agent, a new type of high-energy fuel。 Compared to common bipropellant it has higher energy density。 In addition to, Aluminum ice because the propellant combustion products are Aluminum oxide and water, thus Aluminum ice solid propellant is a new type of environmentally friendly propellant。

The paper is pided into two parts: The first part analyzes the influence of Aluminum ice propellant components on the overall performance of combustion parameters, use thermodynamic calculation software CEA analyzes the H2O2 add Aluminum ice propellant whole by promoting the role of considering the effective range of the content added,Consider adding the Aluminum content on the overall performance parameters of propellants。 In addition to the effects of different initial working pressure on the combustion properties of Aluminum ice propellant。The second part of the use of flow field simulation software Fluent to analyze the gas jet wake flow field under different parameters,They were considered to flow mach number,the nozzle inlet temperature, inlet nozzle pressure, nozzle inlet of a gas jet composition on the composition of wake field, and sorted out by analyzing the relevant conclusions。
