  3. 7. Parametric study on hybrid rocket propulsion system performance measured by the system specific impulse

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Adam Bussmann; [2022]
    Keywords : Hybrid; Hybrid propulsion; Hybrid propulsion system; System specific impulse;

    Abstract : Hybrid rocket motors have become of great international interest during the last couple of years. A hybrid rocket motor is propelled by the use of a solid fuel and a liquid oxidizer. The fundamental principle of the hybrid propelled system is that the liquid oxidizer is injected into a combustion chamber to enable the combustion of the solid fuel. READ MORE
