摘要： PURPOSE:To improve the durability of a sealing for a pintle and obtain a small- sized pintle driving source by installing a driving means which moves the pintle in reciprocation in the axial direction at the basic edge part of the pintle whose top edge projects to the center of the opened port part of a nozzle. CONSTITUTION:When the internal pressure of a tank 3 or the introduced air pressure varies, a gas generator 1 drives a servomotor 19 by an instruction signal supplied from a servoamplifier 27 according to a pressure signal B, and the position detection signal A of a pintle 12 by a potentiometer 26. The pintle 12 is shifted in the axial direction through a ball screw 18 and a nut holder 24, and the opening area of a nozzle 5 varies to adjust the flow rate for the combustible gas. Therefore, in a ram rocket, the combustion in a combustion chamber 4 and the thrust are stabilized by the gas generator 1. In the gas generator 1, only the top edge of the pintle 12 projects from a pintle case 6, and the structure in which the influence of the pressure of the gas stream is little is obtained, and the pintle 12 can be sufficiently driven by a small driving source.

摘要： PURPOSE:To provide a ram rocket fitted with a port cover, which has a sufficient rigidity for blocking a port when a propellent for booster is in combustion and which opens the port without being eliminated to the outside immediately after the end of the propellent combusting. CONSTITUTION:When a propellent 2 for booster provided in a ram combustor 3 is in combustion, a port 3a to take in the air into the ram combustor 3 is blocked with a port cover 8, which opens the port 3a when combustion of the propellent 2 ends. This port cover 8 is installed rotatably using a hinge 17.

摘要： PURPOSE:To increase the specific impulse by furnishing a gas generative agent which causes outflow of high temp. gas to a ram combustion chamber when sustainer propellent is in combustion. CONSTITUTION:When a combustible gas is ignited, a gas generative agent 8 is ignited by an ignitor 9 to generate a high temp. gas, which is injected to the port part of an air intake 6 lying upstream of a ram combustion chamber 3 through a nozzle 10, and thereby a high temp. region is formed upstream of the ram combustion chamber 3. Even though boron unlikely to combust is contained as a metal fuel in a sustainer propellent 12, the combusting efficiency can be enhanced by promoting combustion of the boron, wherein it involves no risk of exhaustion of the residual borron from combustion to the outside, which permits the metal fuel to work while exerting its full characteristics. This enhances the specific impulse due to combustion of the sustainer propellent 12.

摘要： PURPOSE:To preform the secondary combustion of a mixed gas, consisting of combustible gas produced by combustion of a sustainer propellant and air introduced from the outside, in good sustainment, as well as to improve the extent of propulsive performance by setting up a combustion delay part for high temperature gas use in a main combustion chamber. CONSTITUTION:When an igniter 7 is set off, a booster propellant 2 is burned in a main combustion chamber 3, and this combustion gas is jetted out of a booster nozzle 4 whereby a ramjet 1 is started. Afterward, the booster nozzle 4 is separated off at a part of a separating joint 6, while a port cover 12 of an air intake 11 is opened up by a release device 13. In consequence, combustible gas being jetted out of a nozzle 17 and air taken through the air intake 11 are mixed together, and simultaneously this mixed gas is ignited and burned by another igniter 18, thus it is jetted out of another nozzle 5. In this case, a high temperature gas is produced at a combustion delay part 8 set up in front end of the main combustion chamber 3, thereby having the combustion of the said mixed gas sustained so well.

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.
