摘要： PURPOSE:To permit the quick and sure ignition of solid fuel by a method wherein an ignition charge, having a large igniting property by high-temperature air, is provided at the vicinity of an air intake for the solid fuel. CONSTITUTION:A propulsive projectile 1 is provided with an air intake 3 at one end of the outer tube 2 and a nozzle 4 at the other end of the same while a solid fuel 5, having a combustion chamber 6 in the inner space thereof, is provided at the inner periphery of the outer tube 2 and an ignition charge 8, having a large igniting property by high-temperature air, is provided on the side surface of a partitioning 2a, projected to the inner peripheral side of the outer tube 2 at the air intake 3 side of the solid fuel 5, through a restricter 7. The ignition charge 8 is bonded and secured to the inward partitioning 2a of the outer tube 2 through the restricter 7. When the ramjet propulsive projectile 1 is fired from a gun barrel 9 with a transonic speed, shockwave is formed at the air intake 3 and the ignition charge 8 is reacted easily by the high-temperature air of the transonic speed to generate high- temperature combustion flame whereby the surface of the solid fuel 5 is baked, the solid fuel 5 is decomposed easily and is mixed with the inflow high- temperature air thereby igniting the solid fuel 5 quickly and surely.
