两种推进剂能量计算程序的比较——配方均匀试验设计法应用实例

The Comparison of Two Programs for Calculation of Energetic Performance of Propellant Compositions ——The Application of the Uniform Experimental Design Method

利用配方均匀试验设计法设计了有约束条件的C H O N Cl Al体系推进剂配方 .对REAL与CEC - 71能量计算程序计算的推进剂理想状态下平衡流比冲、燃烧室燃温、喷管出口温度、燃烧产物的熵等特性参数作了比较 .t检验结果表明 ,两种程序的计算结果无差异 ,相互吻合 .

Uniform design method is applied to design a series of“C H O N Cl Al” propellant compositions with restricted condition .The parameters,calculated by program REAL and CEC 71,such as the impulse of equilibrium flow, the temperature in combustion chamber,the temperature in nozzle exit and the entropy of combustion products in ideal gas state,are comparised.The texamination indicates that the calculation results of the two programs is identical.
