Microthruster Experimental Analysis
… measure the thrust efficiency of conical shaped microthrusters with varying divergence half angles. The experimental apparatus measured the thrust of micronozzles for various feed pressures in vacuum (to duplicate in space operation) as well as ambient. Calibration experiments confirmed the force …

Electrode Geometry Effects in an Electrothermal Plasma Microthruster
<p>Nanosatellites, such as Cubesats, are a rapidly growing sector of the space industry. Their popularity stems from their low development cost, short development cycle, and the widespread availability of COTS subsystems. Budget-conscious spacecraft designers are working to expand the range of …

A CFD Investigation of Axisymmetric Microthruster Nozzles for Use on Nano-Satellites
<p>The performance of microthruster nozzles (^ 0.1 N thrust) depending on nozzle contour, propellant and surroundings, destined for use in nanosatellite missions, is investigated via a numerical approach using the Wind-US flow solver. An experimental apparatus designed to measure microthruster …

Microthrusters based on the T5 and T6 hollow cathodes
… from the development of a low power, low cost microthruster able to offer propellant savings over conventional alternatives and enable higher energy missions. Such a thruster would also be beneficial in the development of all-electric spacecraft whereby the normally separate reaction control …

Supersonic Constricted Plasma Flows
The Pocket Rocket electrothermal microthruster is a miniaturised electric propulsion system designed for nanosatellites operating in space. A weakly ionised capacitively coupled plasma is ignited in the flowing Ar gas propellant within a constricted discharge chamber at 1 Torr using less than 10 W …

FILM EVAPORATION MEMS THRUSTER ARRAY FOR MICROPROPULSION
Current small sat propulsion systems require a substantial mass fraction of the vehicle involving tradeoffs between useful payload mass and maneuverability. This is also an issue with available attitude control systems which are either quickly saturated reaction wheels or movable high drag surfaces …
