摘要
根据低温发动机系统动态仿真的特点,提出以温度、压力、质量流量和焓流量为基本变量的分段集中参数IRC方法,用此方法建立了发动机主要组件的模型,在AMESim平台上进行了仿真。这种方法提高了发动机系统模块化建模的效率,增加了组件模型的通用性,方便了仿真系统的搭建,并且系统结构简单直观,仿真结果可信实用。
Considering the characteristic of cryogenic rocket engines, an IRC technique basing on variables of temperature, pressure, mass flux and enthalpy flux is developed. With this method, models of main components of rocket engines are established and simulated under AMESim environment. This method will help to improve the modeling efficiency, increase the models＇ versatility and bring the convenience of establishing a whole system model. What＇s more, the structure of model is plain and the result of the simulation is credible.
