Hajtóanyagkezelés translates from Hungarian to English as "propellant management". This term generally refers to the procedures and systems involved in storing, handling, and transferring propellants, which are substances used to generate thrust in rockets and other reaction engines. Effective propellant management is crucial for mission success, ensuring that the required amount of propellant is available at the right time and in the correct state for engine ignition and operation.

The challenges in propellant management stem from the unique properties of propellants. Many propellants are cryogenic, meaning they must be stored at extremely low temperatures to remain liquid. This requires specialized insulated tanks and ground support equipment to prevent boil-off, the evaporation of the cryogenic liquid. Other propellants can be highly toxic, corrosive, or explosive, necessitating stringent safety protocols during transfer and handling to protect personnel and equipment.

Propellant management systems often include complex plumbing, valves, pumps, and sensors to monitor pressure, temperature, and quantity. For long-duration space missions, advanced techniques like zero-boil-off storage and in-situ resource utilization (ISRU) for propellant production are being explored to reduce the mass that needs to be launched from Earth. The accuracy and reliability of these management systems directly impact the performance and safety of launch vehicles and spacecraft.
