摘要
推进剂利用系统是运载火箭的关键分系统之一,可有效提高火箭的运载能力。为进一步了解推进剂利用系统的工作原理与工作特性,采用模块化思想对推进剂利用系统中相互独立的子系统进行数学建模,并在Matlab/Simulink仿真平台上建立了推进剂利用系统动态仿真模型,通过实例仿真对模型的准确性进行了验证。仿真结果表明,该模型具有较高的精度,能够准确模拟推进剂利用系统的工作过程,具有较强的工程实用价值。
Propellant utilization system which can improve payload capability effectively is one of the key subsystems for launch vehicle. In order to realize the working principle of propellant utilization system, the mathematics models based on modularization are built, and dynamic simulation models are constructed with Matlab/Simulink. The simulation results indicate the models with high precision can simulate the working process of propellant utilization system precisely.
