Barros Biología Hydrogen Nuclear Thermal Propulsion Computational Fluid Dynamics Nuclear Thermal Propulsion (NTP) has been extensively ground-tested and is a successfully developed technology, though it hasn’t been officially used in a propulsion system of a space mission. In spite of that, it is the technology most likely to make long distance journeys in space possible. It is considerably more efficient than the traditional chemical rocket engines, regarding propellant consumption for each unit of thrust generated. The reason for that is the greater number of choices regarding the propellant composition. In this work, Hydrogen has been chosen as propellant due to its low molecular mass compared to other possible substances. The aim is to explain how the propellant molecular mass impacts a rocket performance, and to show, by the deduction of an expression for exhaust velocity and an example of Computational Fluid Dynamics (CFD) simulations that, indeed, hydrogen seems to be the best choice available among possible nuclear thermal rocket propellants. 2022 artículo científico 2319-0612 https://www.redalyc.org/articulo.oa?id=722280976002 en http://www.redalyc.org/revista.oa?id=7222 Brazilian Journal of Radiation Sciences application/pdf Sociedade Brasileira de Proteção Radiológica - SBPR Brazilian Journal of Radiation Sciences (Brasil) Num.3A Vol.10 |
