- 摘要:
- 磁等离子体发动机(magnetoplasma rocket engine,MPRE)的离子回旋共振加热(ion cyclotron resonance heating,ICRH)单元将射频能量直接耦合给离子,是发动机的工质加热单元,其加热效果对发动机推力性能有关键影响。为探究ICRH单元的工作规律,建立了用于模拟MPRE的二维轴对称多流体模型,并采用该模型对MPRE中螺旋波等离子体源与不同输入的ICRH单元进行了模拟。计算结果表明:螺旋波等离子体源在放电过程中由于沉积功率分布发生变化而不断经历模式转变过程,模式转变时电子温度出现峰值,等离子体密度迅速上升; 开启ICRH输入后,电子参数基本不变,离子温度有明显提升,表明ICRH单元对离子有明显加热效果,且增加输入电流幅值与输入电流匝数均可显著提高离子温度,实现发动机高比冲工作模式。
- Abstract:
- The Ion Cyclotron Resonance Heating(ICRH)stage is the RF-booster of the Magnetoplasma Rocket Engine(MPRE)in which the RF power is directly coupled to ions. The heating effect of the ICRH stage has an important influence on the thrust performance of the engine. A multi-fluid, two-dimensional, axisymmetric model was developed to study the heating effect of ICRH stage and the helicon plasma source of MPRE together with the ICRH stage of different input parameters were simulated. The results show that the operation mode of helicon plasma source changes continuously during the discharge due to the evolution of the the deposited power. The mode conversions are accompanied by the electron temperature peaks and the plasma density rises dramatically. After the ICRH input is turned on, the electron parameters are basically unchanged while the ion temperature increases significantly, which indicates the ICRH stage has an obvious heating effect on the ions and the ion temperature increases with the amplitude and the turns of the ICRH input current.
