Abstract

PURPOSE:To ignite propellant uniformly to obtain a pressure-time waveform without any disturbance and suppress the maximum bore pressure as low as possible by a method wherein boosting charges are fixed by burnt-out retaining vessels at the circumference of the blades of a flying projectile having the blades for stabilizing the flight of the projectile. CONSTITUTION:Rod type boosting charges 2 are arranged around the blades 1 of a flying projectile so as to include a part B including the blades 1 of the flying projectile while burnt-out retaining vessels 3a, 3b for retaining the boosting charges are provided. The retaining vessels 3a, 3b are made so as to coincide with the configurations of surrounding metallic devices while the vessel 3a is fixed by a primer 6 and the vessel 3b is fixed by the tapers of the blades 1 of the flying projectile. The retaining vessel 3a retains boosting charges 2 so as to surround the primer 6 and retains combustion gas from the primer 6 to achieve the effect of sending the combustion gas axially toward the side of a warhead for a short period of time until the retaining vessel 3a itself is burnt out.

Furthermore, JP-A-57-134699 reports a method for fixing an auxiliary fire tube (7) consisting of an igniter and an extinguishable auxiliary fire tube body to the wing section (1), as shown in Fig. 4. However, it is not sufficient to propagate the combustion gas (ignition energy) of the ignition powder in the axial direction (warhead side), and as shown in Figure 6, the pressure (P) inside the cartridge - time (1 ) When measuring the curve, there is a disturbance in the waveform, and this method does not provide uniform ignition of the propellant.
