This propellant supply to the thruster happens with one or more than one stage of flow control valves. The thrusters are equipped with an internal catalyst bed heater. A thrust is generated when the control valve is commanded to open causing propellant to be fed to the thrust chamber. When the propellant comes in contact with the catalyst a decomposition reaction takes place within the catalyst bed and the hot decomposition gases are then accelerated through a converging-diverging nozzle.<\/p>\n<p>A monopropellant fuel burns without the need for an oxidizer since the oxidizer is already bound into the molecule. This makes the thruster or engine lighter, less expensive, and more reliable.<\/p>\n<p><strong>Click here to learn more about Monopropellant Thrusters featured on SatNow.<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A monopropellant thruster is a thruster that uses a single chemical as its propellant.
