Abstract: Today, hybrid rocket engines (HRE) working on solid fuel andliquidor gaseous oxidizer are a promising trend in the rocket engineengineering area, because they have such advantages as draughtcontrollability, high specific impulse, insensitivity to defects in fuel,and simple design.One of the key challenges in HRE development is the creation ofhigh-energy oxygen-free solid fuels with high combustion rate, andprovision of their full combustion in a gaseous oxidizer flow. Anew trend in the improvement of the characteristics of solidfuels isthe utilization of boron-containing compounds as energy-intensiveadmixtures and organic-metal complex compounds as combustioncatalysts.The tests on the combustion of solid fuel samples based on paraffin inthe gaseous oxygen flow have been carried out in ITAM experimentalfacilities. The tests have been carried out at the atmospheric pres-sure and oxygen flow velocity of 31–27 m/s. The combustion rateof the solid fuel samples increases when amino-borane, and sodiumtetrahydridoborate with a solid oxidizer are added to paraffin
