Chemical rocket engines, also known as combustion engines, are engines that use the energy stored in chemical reactions to boost a rocket or spacecraft into the air. Chemical rocket engines are the most commonly used type of rocket engine and are used to launch both manned and unmanned spacecraft.

A chemical rocket engine works by combining two chemicals, an oxidizer and a fuel, which combust to release energy. This energy is used to propel the rocket in the desired direction. The way in which a chemical rocket engine works is quite simple but the engineering principles behind it are complex.

The two main components of a chemical rocket engine are the oxidizer, which supplies oxygen to the fuel, and the fuel, which generates heat when it combusts. Most rocket engines use liquid fuels and liquid oxidizers, which are stored in separate tanks. These two chemicals are introduced into a combustion chamber where they combust and generate pressure which is used to propel the rocket forward.

Chemical rocket engines are used to launch spacecraft such as the Falcon 9, the Atlas V and the Delta IV Heavy. They are also used on planetary exploration and space missions, such as the Cassini-Huygens mission to Saturn.

Chemical rocket engines have a long history of use and are still the most reliable and efficient way of launching a spacecraft. They are also the most cost-effective option for most missions. However, advances in other forms of propulsion, such as solar electric propulsion, have been made in recent years and these engines may eventually replace chemical rocket engines in some applications.
