“…It was observed that for the discharge vessel, a part required to be a dielectric material, a shift towards alumina ceramics was made due to its more suitable mechanical properties and flexibility in design compared to quartz [11]. The shape has also evolved from a cylindrical shape to a conical one and finally a hemi-spherical design [10,11,12].…”

“…For the grids, different materials have been used for the last 40 years, including carbon-carbon material, graphite, molybdenum and INVAR [10,11,12]. These materials all have excellent thermal properties, especially, very low thermal expansion coefficients.…”

“…The designs may vary regarding the size of the apertures, the thicknesses of the grids and the distance between the grids. Since the study of ion optics is not one of the objectives of this paper, the design of the grids will be influenced by previous works performed on the subject [8,9,10,11,12].…”

Among the various types of plasma thrusters developed over the last few decades for in-space propulsion applications of satellites and spacecrafts, Hall effect thrusters and ion engines are the most studied ones. The work at Bogazici University is concentrated on radio frequency ion thrusters. In this paper the design and manufacturing methods of the BURFIT-80 (Bogazici University Radio Frequency Ion Thruster-80) are explained. The BURFIT-80 is an experimental ion thruster and will be tested in the vacuum chamber at Bogazici University. The Ion Thruster has a cylindrical discharge chamber having an inner diameter and outer of diameter of 80 mm and 88 mm respectively, with a length of 72 mm. A double grid system with 91 holes is implemented. Preliminary calculations suggest that the thruster will generate thrust in the range of 2 to 6 mN. A discussion on material selection and manufacturing methods is presented for the production of the prototype.

In diesem Artikel werden elektrische Triebwerke für Satelliten, Raumsonden und bemannte Raumfahrzeuge vorgestellt, die mit Plasma‐ und Ionenstrahlgeräten zur Materialbearbeitung verwandt sind. Die Notwendigkeit möglichst hoher Strahlgeschwindigkeiten wird erklärt und die Grenzen konventioneller chemischer Antriebe werden aufgezeigt. Anschließend werden zwei wichtige elektrische Triebwerkstypen, thermische Lichtbogentriebwerke und Ionentriebwerke, in ihrer Funktion und ihren Anwendungen beschrieben. Beide Typen sind bereits erfolgreich im Weltraum im Einsatz. Abgeschlossen wird der Artikel durch eine Beschreibung eines Hybridantriebs, der sowohl das Lichtbogenprinzip nutzt als auch die HochfrequenzIonisation verwendet. Er wird als potenzieller Antrieb für eine bemannte Marsmission betrachtet.
