Application of the Orthogonal Design Method in Studies of Ignition Powder for Thermite

摘要

In this paper, the author used Al, Mg, KNO_3 and S produced a new type of high-energy ignition powder to ignite the thermite. The method of orthogonal design has been used to optimize the formulations. In this way, 16 different prescriptions were given. By computer simulation, the energy parameters of all igniter compositions' were figured out. And the igniting effective of the selected powder was tested in the end. From the results, we can see the new powder can ignite the thermite reliably. And the method of orthogonal design applied in ignition powder formulation selection is feasible.
