Laukaisutekijöiden, also known as propellants, are substances used to produce thrust in rockets and other propulsion systems. They are classified into two main types: chemical propellants and non-chemical propellants. Chemical propellants are further divided into monopropellants and bipropellants. Monopropellants are single substances that decompose to produce thrust, while bipropellants consist of two separate substances, an oxidizer and a fuel, which react to produce thrust. Non-chemical propellants include nuclear, solar, and electric propulsion systems, which use different forms of energy to produce thrust.

The choice of propellant depends on various factors, including the mission requirements, the desired thrust level, and the available technology. For example, liquid hydrogen and liquid oxygen are commonly used in rocket engines due to their high specific impulse, which is a measure of the efficiency of a propellant. Solid propellants, such as ammonium perchlorate and aluminum, are often used in smaller rockets and missiles due to their simplicity and reliability.

Propellants play a crucial role in the performance and efficiency of propulsion systems. They determine the thrust level, specific impulse, and overall efficiency of the system. Therefore, the selection and development of propellants are essential in the design and operation of rockets and other propulsion systems.
