Experimental campaign assessed performance and thermomechanical behavior of a hydrogen peroxide monopropellant system for CubeSats, indicating efficacy in both modes.
This work reports the results of an on-ground experimental test campaign performed in the relevant environment (i.e., inside a vacuum chamber) of a blowdown H2O2 monopropellant propulsion system designed for CubeSat applications for the assessment of its propulsive performance and its thermomechanical behavior, both in continuous and pulse modes. The complete experimental characterization of the most important propulsive parameters of the engineering model of the propulsion system has been carried out with a suitably designed diagnostic equipment, consisting of a thrust balance capable of hosting an entire 3U CubeSat and all the relevant sensors. The propulsion system proved to match most of the requirements, both in pulse and continuous mode operations.
