Engines
Engines are devices that convert fuel into mechanical energy to propel a spacecraft. In space and astronautical engineering, engines are crucial components of spacecraft that enable them to move and maneuver in space. There are various types of engines used in space, including chemical rockets, ion engines, and nuclear engines. Chemical rockets are the most commonly used engines in space and work by burning fuel and oxidizer to produce thrust. Ion engines, on the other hand, use electric fields to accelerate ions and produce thrust. Nuclear engines use nuclear reactions to generate heat, which is then used to produce thrust. The efficiency and performance of engines are critical factors in space missions, as they determine the spacecraft's speed, trajectory, and overall success.
