COMPUTER DESIGN OF LOW POWER N2O MONOPROPELLANT THRUSTER [PDF]
Blucher Mechanical Engineering Proceedings, 2014 Development of computer model and preliminary design of the monopropellant (nitrous oxide) thruster that will be working under space vacuum conditions are presented in this paper. To perform such a design, two models have been developed, plug flow reactor and lumped thruster models.
