High thrust ion engine

WebIon drives cannot pay the gravity tax. For an engine to pay the tax the thrust-to-weight rate must be larger than one. An ion drive cannot do that due to the space charge problem. And since thrust-to-weight is a ratio, if your your engine's T/W is 0.001, an array of ten thousand engines will still have a T/W of 0.001 WebMay 5, 2024 · The thrust of the measurement. The heated plasma creates a torch-like flame as the hot gas exits the waveguide, generating thrust. Measuring the gas pressure (thrust) turned out to be difficult ...

High Power Electric Propulsion - Wikipedia

WebFor high thrust, power is routed predominantly to the first stage producing more plasma (more thrust) at a lower exhaust velocity (low Isp). For high Isp, less power is fed to the first stage and more to the second, reducing the plasma production but increasing its temperature and hence its exhaust velocity. High power density.
