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 third law of motion, and "propel" a vehicle, projectile, or fluid payload. In vehicles, the engine that expels the propellant is called a reaction engine.

The meaning of PROPELLANT is capable of propelling. How to use propellant in a sentence.

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, as with a chemical rocket, or from an external source, as with ion engines. Rockets create thrust …

All the substances that create this reaction mass directly (for example, water rockets) or indirectly by a chemical reaction (for example, Falcon 9) constitute Rocket Propellants. So, by definition Rocket propellants includes both the oxidizer and the fuel.

Mar 24, 2024 · In the context of rocketry, propellant is the fuel and oxidizer combination that generates the thrust needed to launch a rocket into space. Without propellant, rockets would not be able to overcome Earth’s gravity and reach the speeds necessary to escape the atmosphere.
