Abstract
A thruster assembly, including a switch connected to a power source, a thruster, a propellant tank for storing and pressurising a propellant, and a propellant channel for guiding the propellant to the thruster. The thruster includes a space for receiving the propellant from the propellant channel, an electrically controlled heating element, a thruster body having a first thermal expansion coefficient, a valve component having a second thermal expansion coefficient, which is different than the first thermal expansion coefficient, inside the thruster body, and a nozzle, wherein the valve component includes a sealing surface closing the nozzle in a first temperature, and the electrically controlled heating element in response to actuation of the switch heats said thruster to a second temperature where the thermal expansion of the thruster opens the nozzle.
