| 摘 要： | 运用热力学平衡常数法,在计算磁流体发电机用推进剂燃烧产物组成和燃温等热力学参数的基础上,通过应用沙赫方程和燃烧产物电导率计算模型,计算了磁流体发动机用含Cs盐复合推进剂燃烧产物的电导率,揭示了电导率随Cs盐、铝含量以及电导率随温度、压力的变化规律.结果表明: 铝含量一定,当Cs盐含量在5%～10%时,燃烧产物电导率达到最大; 燃温越高、燃烧室压力越小,燃烧产物电导率越高.

| Abstract: | The electrical conductivity of combustion products of composite propellant containing Cs salt which used in magneto-hydro-dynamic (MHD) generator were calculated through Sahe equation and model of electrical conductivity. The basic thermodynamic parameters used in the model of electrical conductivity were calculated by applying thermodynamic equilibrium constant equation. Through theoretical calculation,the change of electrical conductivity along with the Cs salt content and aluminum content was obtained. T... |
