Conventional Rocket Engines

Conventional rocket engines generate thrust by burning fuel to produce high-pressure, high-temperature gases, which then rapidly exit the engine’s nozzle. This action creates a reactive force that propels the rocket forward, based on Newton’s third law: for every action, there's an equal and opposite reaction. These engines typically use liquid or solid propellants, with liquid engines offering controllability and reusability. They are essential for launching spacecraft beyond Earth's atmosphere, providing the powerful, reliable thrust needed to overcome gravity and reach space.
