One way of improving ignition performance of ignition tube

According to the demand of large-caliber cannon ignition system design, combining the practice of engineering development and manufacture, a new kind of ignition powder backfill structure was proposed, which is to put pressure on black powder and make high-density caky powder, then load it into metallic center ignition. The geometrical shape of caky black power and loading density are modified to modulate ignition pressure, so as to match different propellant structure.
