The 20N Monopropellant Thruster from the Orbital Propulsion Centre is a Monopropellant Spacecraft thruster that has a thrust range of 7.9-24.6 N. It has a nominal specific impulse range of 222-230 sec and a supply pressure range of 5.5-24 bar. This thruster works with monopropellant grade Hydrazine (N2H4) propellant and has a mass flow range of 3.2-10.4 g/s. It is equipped with an internal redundant catalyst bed heater and provides thermal insulation to guarantee optimum start-up. The thruster is qualified for a total impulse greater than 517000 Ns and has a total operating time of 10.5 hrs. It has a mass of 0.650 Kg and a nozzle area ratio of 60. The thruster is ideal for attitude, trajectory, and orbit control of small satellites and midsize satellites.
