The function of a propellant in a model rocket is to provide the necessary thrust to propel the rocket upward. It undergoes a rapid combustion process, generating hot gases that expand and are expelled out of the rocket's nozzle, creating lift according to Newton's Third Law of Motion. The efficiency and burn rate of the propellant determine the rocket’s performance, including its maximum altitude and speed. Properly formulated propellants ensure reliable and safe launches.
A rocket functions by burning an internal fuel source as a propellant. The thrust is then pushed through a nozzle to increase performance.
The propellant in a rocket serves as the fuel that is burned to generate the thrust needed for propulsion. It undergoes a chemical reaction that releases energy, creating a high-pressure exhaust that is expelled out of the rocket nozzle, producing thrust in the opposite direction based on Newton's third law of motion.
In a real rocket, there is short a time in atmosphere and the aerodynamics are less important. In a model rocket, all flight in the atmosphere and the aerodynamics are very important. In a real rocket, it has a liquid or solid rocket engine and a large propellant mass fraction. In a model rocket, it has a solid rocket engine and a small propellant mass fraction . In a real rocket, there are four forces during atmospheric flight. In a model rocket, there are four forces throughout flight. In a real rocket, there is a long powered flight . In a model rocket, it has a very short powered flight . In a real rocket, it has passive stability and active control . In a model rocket, it has passive stability and no control. In a real rocket, it has expensive materials such as aluminum, titanium, and nickel alloy. In a model rocket, it has inexpensive materials such as balsa, cardboard, and plastic. In a real model, there is a high speed and the heating is very important. In a model rocket there is low speed and the heating is not important.
A solid propellant rocket works by using a fuel and oxidizer that are chemically mixed and solidified into a single mass, known as solid propellant. When ignited, the combustion of this propellant produces high-pressure gas that expands rapidly. This gas is expelled through a nozzle at the rear of the rocket, generating thrust according to Newton's third law of motion. As the propellant burns, the rocket continues to accelerate until the fuel is depleted.
Two common types of rocket propellant are liquid propellant and solid propellant. Liquid propellant consists of fuel and oxidizer stored separately and combined in the combustion chamber, allowing for controlled thrust and engine shutoff. Solid propellant, on the other hand, consists of a mixture of fuel and oxidizer that is preloaded into the rocket, providing a simpler design but less control over the burn once ignited. Each type has its advantages and applications in different rocket systems.
The length of time from ignition of propellant to when all propellant has been consumed.

The only use I know of for this term is in model rocketry. A model rocket's engine is made up of several layers of propellant. After the propellant, the primary layer that shoots the model rocket up, has burned out, a layer called the "delay charge" burns. This layer doesn't push the rocket, it just puts out smoke so you can see where the rocket is and creates a delay before the last layer called the "ejection charge" which pushes out the parachutes or whatever method method is used to recover the rocket. I'm adding a link to a wikipedia page on model rocketry. If there is another meaning, maybe someone who knows will come by.
ROBERT HUTCHING GODDARDOn 6th March 1926 he got succeeded in launching its first liquid propellant rocket.
The three basic parts of a rocket are the rocket engine, which provides thrust for liftoff, the propellant tanks, which store the fuel and oxidizer, and the payload, which is the cargo the rocket is carrying into space.
