A solid-propellant rocket is a solid fuel-based rocket engine, the first being solid-fuel rockets propelled by gunpowder, due to the 13th century by the Chinese.
The plastic material that is burned is called grain and consists of fuel and oxidized material in a solid-state. It is known that the fuel and oxidizer of the solids are not ignited on contact, but ignited by one of two methods, the first igniting a mixture of potassium nitrate and sulfur, and the second by creating a chemical reaction of a liquid chlorine compound that is sprayed on the grain.
Solid fuel combustion takes less time than liquid fuel combustion, but produces less energy than the same amount as liquid fuel combustion, solid fuel represents little risk when ignited, and does not require pumping devices, but is difficult to stop and reignite again.
Most of the use of a solid-propellant rocket is in wars, where ferry rockets have sufficient power for continents and are also used as sound rockets.
