rakettmootori põlemiskambrisse juhitavad ained: kütus, hapendi ja lisandid
a material, such as a fuel, an oxidizer, an additive, or any compound or mixture of these, carried on a rocket vehicle that releases energy during combustion and thus provides thrust to the vehicle
The propellant attains its velocity by burning with an oxidizer in a high-pressure chamber. The resultant high energy exhaust is then funneled through a converging or diverging nozzle. This velocity, coupled with the right mass properties of the propellant, provides the power, or energy, required to get the vehicle into space.
