A solid-propellant rocket or solid rocket is a rocket with a rocket engine that uses solid propellants (fuel/oxidizer). The earliest rockets were solid-fuel rockets powered by gunpowder . The inception of gunpowder rockets in warfare can be credited to the ancient Chinese, and in the 13th century, the Mongols played a pivotal role in ...
Solid fuel rockets have lower specific impulse, a measure of propellant efficiency, than liquid fuel rockets. As a result, the overall performance of solid upper stages is less than liquid stages even though the solid mass ratios are usually in the .91 to .93 range, as good as or better than most liquid propellant upper stages.
Ammonium perchlorate composite propellant (APCP) is a solid rocket propellant. It differs from many traditional solid rocket propellants such as black powder or zinc-sulfur, not only in chemical composition and overall performance but also by being cast into shape, as opposed to powder pressing as with black powder. This provides manufacturing ...
North Korea's Hwasong-18 intercontinental ballistic missile (ICBM), launched for the second time on Wednesday, uses solid-fuel technology, giving it the capability to launch with little preparation.
Hybrid-propellant rockets use a combination of solid and liquid propellant, typically involving a liquid oxidizer being pumped through a hollow cylinder of solid fuel. All current spacecraft use conventional chemical rockets (solid-fuel or liquid bipropellant) for launch, though some [note 3] have used air-breathing engines on their first stage ...
Solid-fuel rockets (or solid-propellant rockets or motors) are chemical rockets which use propellant in a solid state. Liquid-propellant rockets use one or more propellants in a liquid state fed from tanks. Hybrid rockets use a solid propellant in the combustion chamber, to which a second liquid or gas oxidiser or propellant is added to permit ...
Solid fuels are extensively used in rocketry as solid propellants. [1] Solid fuels have been used throughout human history to create fire [2] and solid fuel is still in widespread use throughout the world in the present day. [3] [4] Solid fuel from biomass is regarded as a renewable energy source which can contribute to climate change ...
Pages in this category describe sounding rockets or carrier rockets which use solid-fuel exclusively, or solid-fuel rocket stages. This category does not include solid-fuel rockets used as missiles .
