We conducted a comparative evaluation of the effectiveness of the hybrid rocket engine (HRE) and the solid-fuel rocket engine for meteorological rocket with a fuel mass of 540 kg.We have considered various combinations of oxidizer and fuel, based on which we determined the energy characteristics of the HRE. The study allowed us to assess the ballistic performance of the HRE, to analyze the peculiarities of the combustion process, as well as the selection and design of the forms of solid fuel charge.
Keywords: ballistic efficiency, hybrid rocket engine, intra-ballistic parameters, meteorological rocket, methodology of calculation.
