Explanation
The linear burning rate of propellant is defined as the distance that the propellant disappears along the normal direction of combustion surface per unit time. Its mass burning rate is defined as the mass ft with phase disappearing between propellants per unit time and per unit area. The energy release rate of propellant is controlled by its shape (combustion area) and combustion speed, so burning rate is one of the important performance indicators of propellant.
