Propellants
Propellants are the chemical substances used to create thrust in rockets and other spacecraft. They are typically composed of a fuel and an oxidizer, which when combined, undergo a chemical reaction that produces hot gases that are expelled out of the rocket nozzle, creating thrust. Propellants can be either liquid or solid, and each type has its own advantages and disadvantages. Liquid propellants are typically more efficient and can be throttled, making them ideal for use in spacecraft that require precise control over their velocity and trajectory. Solid propellants, on the other hand, are simpler to store and handle, making them ideal for use in missiles and other military applications. However, they cannot be throttled and are less efficient than liquid propellants. Propellants are a critical component of any spacecraft, and their development and optimization is a key area of research in the field of astronautical engineering.
