| 摘要 |
<p>This invention relates to propulsion systems used for station-keeping in the atmosphere. The Corona Ion Engine has no moving parts, utilizes the ambient atmosphere as a propellent, is solar powered and has an efficiency that approaches 90 %. Corona Ion Engines (47) utilize the principle of corona ionization to produce thrust by introducing negatively charged emitter electrodes (48) at a tip (49) into the atmosphere to eject, by field emission, energetic electrons.</p> |
