向航天器的电动推进器提供推进流体的经改进的流调节系统
摘要：
一种用于对航天器的电动推进器的推进流体流速进行调节的系统，所述航天器包括推进流体箱和连接到该箱的出口的流速调节器；所述流速调节器包括受计算机控制并且被适配成加热推进流体并修改其物理属性以便改变离开所述箱的推进流体的流速的加热器元件；所述系统的特征在于所述计算机还包括多条经验校准曲线，所述经验校准曲线被经验地确定以用于根据加热量级并根据环境参数来定义推进流体的流速，这样，所述计算机也执行确定推进流体的流速的功能。
摘要（英）：

A system for regulating the flow of a propellant fluid for an electric thruster of a space vehicle, comprising a propellant fluid reservoir and a flow regulator mounted at the outlet of said reservoir, the flow regulator comprising a heating element controlled by a computer and designed to heat the propellant fluid and modify the physical properties thereof in order to vary the flow of propellant fluid exiting the reservoir, said system being characterised in that the computer further comprises a plurality of empirically determined empirical calibration curves defining the flow of propellant fluid depending on the intensity of heating and environmental parameters, such that said computer also performs a function of determining the flow of propellant fluid.
