Design, Fabrication and Characterization of MEMS Micro-resistojet Thrusters

Small satellites require efficient propulsion systems for attitude and orbit control. This thesis focuses on the development and characterization of two distinct types of micro-resistojet thrusters, namely Vaporizing Liquid Micro-resistojet (VLM) and Low Pressure Micro-resistojet (LPM). Both concepts are developed at TU Delft and are designed to...

Novel fabrication method for a hot gas supersonic micro-thruster

A key element in the development of more capable nano- and pico-satellites is the development of high specific impulse micro-propulsion systems, which allow for more challenging space missions to be flown. One such system being developed at TU Delft is a micro-resistojet with a planar supersonic nozzle geometry. This is currently fabricated by...

The low-pressure micro-resistojet: Modelling and optimization for future nano- and pico-satellites

The aerospace industry is recently experiencing growing interest in very small spacecraft like nano- and pico-satellites. However, these very small satellites are still being developed in most cases without a dedicated propulsion system limiting their capabilities. The micro-resistojet has been recognized as a suitable propulsion system for...

An analytical model for characterizing the thrust performance of a Low-Pressure Micro-Resistojet

There is a clear trend towards the developments of micro-propulsion system to enhance the capabilities of nano- and pico-satellites. A promising propulsion option to meet the strict requirements of these small satellites is the Low-Pressure Micro-Resistojet (LPM) which works under rarefied gas dynamic regime. To simplify the engineering...

Fabrication and characterization of low pressure micro-resistojets with integrated heater and temperature measurement

Three low pressure micro-resistojets (LPM) with integrated heater and temperature measurement were designed, manufactured and characterized at Delft university of technology. The devices were manufactured using silicon-based micro electro mechanical systems (MEMS) technology including a heater made of molybdenum for better operations at high...
