The Space Propulsion Laboratory (SPLab) operates in the field of space propulsion with reference to solid, liquid and hybrid propellant systems, from both experimental and numerical viewpoints. The research group is now committed to developing innovative solution, such as low environmental impact formulations of solid propellant, unconventional hybrid engine configurations for in-space applications and green oxidizer-fuel combinations designed for new generation storable liquid propulsion. Since 1976, year of foundation, it is also consistently active in the study of combustion of solid phase energy materials with research activities on stationary combustion rates, static and dynamic extinction, deflagration limit pressure, characterisation of the combustion products, ignition and transient combustion phenomena. The SpLab collaborates regularly both in the academic field and in the industrial sector with other research centers at a national and international level.In 2018 it founded ReActive-Powder Technology, a Politecnico di Milano spin-off, with expertise in making high performance energy materials through mechanical activation processes.
