👉 The launch fluid, also known as the launch oil or launch carrier fluid, is a specialized liquid used in rocket propulsion systems to facilitate the separation and ignition of the rocket's main engine. It is typically a low-viscosity, high-temperature fluid that forms a thin film between the combustion chamber and the engine's nozzle, ensuring a clean and efficient separation of these components. This fluid helps in managing the extreme temperatures and pressures during engine ignition, preventing damage to the engine's internal structures. Additionally, it aids in cooling the engine and maintaining stable combustion, thereby enhancing overall engine performance and reliability during the launch phase.
