An Investigation into Injector Architecture for Sub-Newton Monopropellant Propulsion
This paper presents an exploration of injector architecture candidates, including orifice and Poiseuilletype injectors, for sub-newton monopropellant thrusters. While the work here is specific to High Test Peroxide, it is expected to be applicable to other monopropellants. This methodology presented here seeks to underpin the fluid mechanics through flow characterisation and hot firing of each injector, with analytical, experimental and computational methods. Experimental results broadly follow calculations and simulations, although do not fully agree. Further work is required to fully understand the microscale fluid dynamics, especially as chugging may not be as significant for sub-newton scale monopropellant thrusters.

Abstract
This paper presents an exploration of injector architecture candidates, including orifice and Poiseuilletype injectors, for sub-newton monopropellant thrusters. While the work here is specific to High Test Peroxide, it is expected to be applicable to other monopropellants. This methodology presented here seeks to underpin the fluid mechanics through flow characterisation and hot firing of each injector, with analytical, experimental and computational methods. Experimental results broadly follow calculations and simulations, although do not fully agree. Further work is required to fully understand the microscale fluid dynamics, especially as chugging may not be as significant for sub-newton scale monopropellant thrusters.
