An experimental study on internal ballistic performance of an impulsive SRM with a large value of L  for a middle way guidance system of a long range rocket has been completed at a dynamic ground test

such as static firing test

dynamic spinning test and ambient temperature limitation test.The tests show a good agreement of experimental data with the predicted ones.It is indicated from experimental results that the major performance of the impulsive SRM meets the requirements of dynamic testing with the rocket guidance system

but also is associated with some evident features of the impulsive SRM with large value of L .
