The results of experimental combustion tests of some gunpowder types (ballistite, pyroxylin, mixed, model compositions) at pressure decay from the initial level of P i =4÷250 MPa to the final level of P f =0.1÷50 MPa with the pressure decay speeds of P ' = (1 ÷ 800)∙10 2 MPa/sec are presented in the paper.
