论文摘要
引入了一个新的概念，用于产生用于太空推进的推力。当将磁性螺旋（连接的磁场线）注入环形通道时，以浆液形式（封闭磁环中的限制等离子体）的形式产生了能量推力。该概念使用静态电场和磁场的新型配置，利用当前的表单不稳定性自发，连续地通过磁重新连接产生浆液。使用扩展的磁性水力动力学模型在全球环形几何形状中模拟产生的低温血浆。由于系统大小的浆液是从重新连接位点出现的Alfgenic流出，因此其推力与磁场强度的平方成正比，理想情况下并不取决于血浆的离子物种的质量。在模拟中观察到20至500 km/s的排气速度，可通过线圈电流控制。
A new concept for generation of thrust for space propulsion is introduced. Energetic thrust is generated in the form of plasmoids (confined plasma in closed magnetic loops) when magnetic helicity (linked magnetic field lines) is injected into an annular channel. Using a novel configuration of static electric and magnetic fields, the concept utilizes a current-sheet instability to spontaneously and continuously create plasmoids via magnetic reconnection. The generated low-temperature plasma is simulated in a global annular geometry using the extended magnetohydrodynamic model. Because the system-size plasmoid is an Alfvenic outflow from the reconnection site, its thrust is proportional to the square of the magnetic field strength and does not ideally depend on the mass of the ion species of the plasma. Exhaust velocities in the range of 20 to 500 km/s, controllable by the coil currents, are observed in the simulations.
