Solid fuel rockets use a mixture of fuel and oxidizer that is preloaded into a solid form. When ignited, the fuel burns uniformly, producing hot gases that expand and are expelled through a nozzle, generating thrust. This design makes solid fuel rockets simpler and more reliable than liquid fuel rockets, as they do not require complex pumping systems. These rockets are commonly used in various applications, including military missiles and space launch vehicles. Notable examples include the Space Shuttle boosters and the Minuteman intercontinental ballistic missile. Their ease of storage and readiness for launch make them popular choices in many fields.
