Lökésszer

Lökésszer is a Hungarian term that translates to "propellant" or "rocket fuel." It refers to any substance or mixture of substances that, when burned or reacted, produces a large volume of hot gas that is expelled at high velocity, generating thrust. This principle of action and reaction is the basis for rocket propulsion.

Propellants can be broadly categorized into several types. Solid propellants consist of a fuel and an oxidizer mixed together in a solid form. Once ignited, they burn at a controlled rate, producing hot gases. Liquid propellants involve separate fuel and oxidizer components that are stored in liquid form and pumped into a combustion chamber where they mix and react. These offer greater control over thrust. Hybrid propellants combine a solid fuel with a liquid or gaseous oxidizer.

The performance of a lökésszer is often measured by its specific impulse, which indicates how efficiently it generates thrust per unit of propellant consumed. Higher specific impulse means more thrust can be achieved for the same amount of fuel. The development of effective and safe lökésszer has been crucial for advancements in rocketry, enabling space exploration, satellite launches, and various other applications.
