Perspectives for hybrid propulsion development in Brazil

Abstract

The production of small, micro and nano satellites is growing exponentially, as a result, the need for launch vehicles also increases, giving rise to a strong concurrency for a place in this important international market. Hence, developing countries must make the effort to enter this competition, on this decade, while there is still the opportunity. This attempt should comprise the development of a space research program largely related to the development of launch vehicles to fit the demands of placing satellites in low and high orbits. This requirement should motivate the launcher service provider to find an economic way of boosting satellites of different geometries. For this reason, it is not surprising to explore substitute ways to launch small satellites in a suitable time with cheaper costs by the use of hybrid rocket motors, a well-known rocket propulsion system recognized by the relatively smaller production costs and high safety. Therefore, this essay aims to present the viability of this technology, dealing primarily with the design and operational relevant matters, focusing on the development of the hybrid propulsion technology in Brazil.
