A black powder rocket motor is a type of propulsion system that uses black powder as its propellant to create thrust. Black powder, also known as gunpowder, consists of a mixture of potassium nitrate (saltpeter), charcoal, and sulfur. It has been used historically in firearms and fireworks, and in this context, it serves as a solid rocket fuel.
