The study on waste grain rate can reduce or eliminate the waste drug for maximum use of solid rocket grain. By the method of analytic formulae, the burning area and rate formulae of waste grain were derived and an example of waste grain burning law was given. The results show that the larger the arc and slot length are, the larger the rate is, and with the design parameters increase, the increase amplitude of the rate becomes smaller, the rate has a nearly linear relationship with slot depth: The smaller the depth is, the less the rate is.
Key words： slotted tube grain; waste grain rate; solid rocket; burning law
