Cervone, A. (author), Cordeiro Guerrieri, D. (author), de Athayde Costa e Silva, M. (author), Leverone, F.K. (author)Electrothermal propulsion can be seen as an intermediate concept between electrical and chemical propulsion. Propellant heating typically happens by means of a resistance (resistojet) or an electrical discharge (arcjet). For the extremely miniaturized applications that will be discussed in this chapter, resistojets are by far the most...book chapter 2022

Ganani, Chaggai (author)Micropropulsion is universally considered to be a key technology enabling nano- and pico- satellites to perform more complex missions. However, past research has shown that nozzle efficiencies at the microscale are far inferior to their macro scale counterparts. These low efficiencies can be attributed to the relatively high viscous losses...master thesis 2019

Makhan, Rajeev (author)This thesis includes an experimental study about the performance of a third generation MEMS-VLM chip. The influence of the throat Reynolds number on the discharge factor and the nozzle quality was investigated. This was done by measuring the mass flow and thrust force for a chamber pressure range of 2-5 [bar] using nitrogen gas as propellant. It...master thesis 2018
