摘要:
The invention relates to a structure and a method for a drive device pertaining to a space missile comprising at least one ion accelerator arrangement, whereby a neutralising ion source is consciously rendered superfluous and an ion flow with a positive charge excess is expelled. The charge balance is compensated by capturing slow, positively charged particles which are attracted from the environment by a low potential difference, wherefore metallic outer surfaces of the satellite are connected to the cathode or the generator of the ion accelerator arrangement in a galvanically direct or indirect manner.

The invention relates to various advantageous embodiments of a plasma-accelerator configuration, especially for the configuration and design of electron sources used for ionizing the working gas and/or neutralizing the discharged plasma jet.
摘要:
The invention relates to a surface section that is exposed to an ion flow, in particular for a drive arrangement in a spacecraft, comprising an electrostatic ion accelerator arrangement. According to the invention, in order to reduce erosion, an intermediate potential energy surface is provided, said surface being advantageous in that it allows a magnetic field that is essentially parallel to the surface section to be formed.
摘要:
The invention relates to a plasma accelerator arrangement with a directed electron beam which is introduced into a plasma chamber. According to the invention, the chamber has a ring-shaped structure and the electron beam has a hollow cylindrical shape. A beam-guiding magnet system and optionally, an electrode system, is preferably configured with multiple levels in an adapted toroidal shape.
摘要:
The invention relates to a multistage plasma accelerator system that comprises at least one intermediate electrode between the plasma chamber between electrodes that include each other. An especially good efficiency can be achieved by way of an uneven distribution of potential to the potential stages formed by the plurality of electrodes having a high potential gradient of the last stage, when the plasma beam emerges, and by a special shape of the magnetic field prevailing in the plasma chamber of the last stage.
摘要:
The invention relates to a plasma accelerator arrangement with electrostatic acceleration of ions by an electric field running through a plasma chamber essentially parallel to the beam direction with a plasma geometry of the cylindrical type with a preferably circular cross-section. Various measures to reduce divergence of the emitted plasma beam are disclosed, which may be applied individually or advantageously in combination.
摘要:
Disclosed is an ion accelerator arrangement with a special magnetic field structure in which the magnetic field alternately extends in a mostly longitudinal and transversal direction. The ionization chamber for said ion accelerator arrangement has a specific geometry, the wall of the ionization chamber having a non-cylindrical shape that is adjusted to the course of the magnetic field.
摘要:
The invention relates to an ion accelerator arrangement comprising an electrostatic acceleration field between a cathode to which a frame potential is applied and an anode to which a high-voltage potential is applied. Said ion accelerator arrangement further comprises a gas supply system into which a gas-permeable, open porous insulator member is introduced. Also described is a high-voltage insulator arrangement that comprises such an insulator member and is suitable, inter alia, for such an ion accelerator arrangement and for the corona-resistant insulation of other components to which a high voltage is applied.
摘要:
The invention relates to a drive arrangement in a spacecraft, comprising several drive units (TW1,TW2,TW3), several individually controllable drive units that can be continuously applied to a common, constant voltage potential (HV), and a control of the axial thrust in the respective drive units is achieved due to the fact that the production of plasma in the respective drive units is individually controlled. In particular, the time-variable control of the production of plasma occurs by the time-variable control of the flow of neutral working gas (AG) in the ionisation chamber (IK).
