Korolevbased

Korolev-based refers to a type of rocket engine that utilizes kerosene as its primary fuel. This type of engine is commonly used in the Russian space program, particularly in the Soyuz and Proton rocket families. Kerosene, also known as RP-1, is a highly refined form of kerosene that is chosen for its high energy density and relatively low cost. The Korolev-based engine operates by injecting liquid oxygen (LOX) into the combustion chamber, where it mixes with the kerosene to produce thrust. This combination of fuels is known for its reliability and efficiency, making it a popular choice for both military and civilian space applications. The engines are typically designed to operate in a staged combustion cycle, which involves pre-burning some of the propellant to drive the turbopumps, thereby increasing efficiency. Despite its widespread use, the Korolev-based engine has faced criticism due to its environmental impact, particularly the release of soot and other pollutants during combustion. However, ongoing research and development efforts aim to mitigate these issues and improve the engine's overall performance and sustainability.
