szilárdüzemanyagú

szilárdüzemanyagú is a Hungarian term that translates to "solid-fuel" or "solid-fueled" in English. It refers to a system, engine, or device that uses solid material as its primary source of energy. This type of fuel is typically combustible and undergoes a chemical reaction, usually combustion, to release heat and produce mechanical work or other forms of energy.

Examples of szilárdüzemanyagú systems include various types of rocket engines, where solid propellants are packed into a casing and burn to generate thrust. These are commonly used in space launch vehicles and military applications. Another example is the use of solid fuels in traditional furnaces and boilers for heating purposes, where materials like wood, coal, or biomass are burned to produce heat. Certain types of internal combustion engines can also be designed to run on solid fuels, although this is less common than liquid or gaseous fuels in modern applications. The term emphasizes the physical state of the fuel rather than its specific chemical composition.
