A propellant (or propellent) is a mass that is expelled or expanded in such a way as to create a thrust or another motive force in accordance with Newton's...

hypergolic in Wiktionary, the free dictionary. A hypergolic propellant is a rocket propellant combination used in a rocket engine, whose components spontaneously...

Rocket propellant is used as reaction mass ejected from a rocket engine to produce thrust. The energy required can either come from the propellants themselves...

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...

liquid-propellant rocket or liquid rocket uses a rocket engine burning liquid propellants. (Alternate approaches use gaseous or solid propellants.) Liquids...

Firearm propellants are a specialized type of propellant used to discharge a projectile (typically a bullet, slug, or pellets) through the barrel of a...

Smokeless powder is a type of propellant used in firearms and artillery that produces less smoke and less fouling when fired compared to black powder....

cartridge case that typically holds the primer, propellant and projectile together as a unit. Instead, the propellant and primer are fitted to the projectile...

The highest specific impulse chemical rockets use liquid propellants (liquid-propellant rockets). They can consist of a single chemical (a monopropellant)...

A propellant tank is a container which is part of a vehicle, where propellant is stored prior to use. Propellant tanks vary in construction, and may be...

An orbital propellant depot is a cache of propellant that is placed in orbit around Earth or another body to allow spacecraft or the transfer stage of...

A rocket engine uses stored rocket propellants as the reaction mass for forming a high-speed propulsive jet of fluid, usually high-temperature gas. Rocket...

using propellant or a jet engine using fuel, generates thrust. A propulsion system with a higher specific impulse uses the mass of the propellant more...

to exhaust expelled at high speed. Rocket engines work entirely from propellant carried within the vehicle; therefore a rocket can fly in the vacuum of...

cartridges. Ball propellant can be manufactured more rapidly with greater safety and less expense than extruded propellants. Ball propellant was first used...

particles. It comprises a can or bottle that contains a payload, and a propellant under pressure. When the container's valve is opened, the payload is forced...

Propellant 23 may refer to: Fluoroform Propellant 23 (The Avengers) This disambiguation page lists articles associated with the title Propellant 23. If...

RP-1 (alternatively, Rocket Propellant-1 or Refined Petroleum-1) is a highly refined form of kerosene outwardly similar to jet fuel, used as rocket fuel...

perchlorate composite propellant (APCP) is a solid rocket propellant. It differs from many traditional solid rocket propellants such as black powder or...

A propellant management device (PMD) provides a way to expel propellant in a low-gravity environment. Devices can use surface tension as the primary expulsion...

cycle of a bipropellant rocket engine. In the staged combustion cycle, propellant flows through multiple combustion chambers, and is thus combusted in stages...

In aerospace engineering, the propellant mass fraction is the portion of a vehicle's mass which does not reach the destination, usually used as a measure...

a projectile. In guns, internal ballistics covers the time from the propellant's ignition until the projectile exits the gun barrel. The study of internal...

Moon, and Mars, Starship will rely on orbital refueling; a ship-to-ship propellant transfer demonstration is expected to occur in 2025. SpaceX also plans...

similar to a gridded electrostatic ion thruster and used mercury for propellant. Suborbital tests were conducted during the 1960s and in 1964, and the...

single package. Until the 20th century, black powder was the most common propellant used but has now been replaced in nearly all cases by modern compounds...

Aluminum-Ice Rocket Propellant, or ALICE, is a rocket propellant that consists of nano-aluminum powder and water. After mixing, the material is frozen...

firearm ammunition packaging a projectile (bullet, shot, or slug), a propellant substance (smokeless powder, black powder substitute, or black powder)...

approximately 12 people, with goals to "build out and troubleshoot the propellant plant and Mars Base Alpha power system" and establish a "rudimentary base...

A hybrid-propellant rocket is a rocket with a rocket motor that uses rocket propellants in two different phases: one solid and the other either gas or...
