Abstract: The test on relativity of the burning rate in φ-118mm standard motor and in certain solid motor is conducted. It is demonstrated, that among the burning rates of the propellant grain sample, the φ-118mm standard mptor and the certain solid motor no relativity exists in their respective tolerances.Strong relativity is found only between the burning rates in the φ-118mm standard motor and the certain solid motor. A mathematical regressive equation on burning rates is presented in this paper, which is first mentioned and applied in commercial production of tactical solid motors in our country.
