摘要
针对采用液体推进剂火箭发动机的空间推进系统，推导了系统液路和气路的通用积分形式方程。对不同部件，根据其特点进行方程简化，给出了以压力为自变量表示流量的部件静态数学模型。这为开展空间推进系统的静态仿真研究奠定了基础。
The general integral equations are derived for liquid and gas components of space propulsion systems with liquid propellant rocket engine. The equations are simplified for various components according to their features, and the static mathematical models are given in the form of functions in which the pressures are the independent variables and the flow rates are the dependent variables. These models lay the foundation to develop static simulation for space propulsion systems.
