    • PROBLEM TO BE SOLVED: To realize restraint of oscillating combustion without influencing upon characteristics of combustion speed, etc., of a solid propellant by providing a solid particle producing mechanism to produce solid particles to function as an oscillating combustion restrainer on the upstream side of the solid propellant. SOLUTION: A solid rocket 11 is constituted by providing an insulation 13 on the inner surface of a cylindrical pressure container 12 and loading a solid propellant 14 in the inside of this insulation 13. A nozzle 15 is provided on the downstream side of the solid propellant 14, and an igniter 16 is provided on the upstream side of the solid propellant 14. The igniter 16 contains an oscillating combustion restrainer and ZrC powder to function not to inhibit turning to be smokeless or lean-smoke, and this igniter 16 is structured to doubly work as a solid particle producing mechanism 17. Consequently, on the solid rocket 11, ZrC solid particles are supplied from the solid particle producing mechanism 17 doubly to use by the igniter 16 while the solid propellant 14 is ignited by the igniter 16 and burns and thrust is generated as combustion gas is blown out from the nozzle 15.

    • PURPOSE:To provide a combustion heater which is capable of stably producing high temperature high pressure gas with uniform total temperature, and in which reduction of heat load of an internal cylinder with the aid of secondary air is satisfactory, and in which damage by a fire due to adhesion of a kept flame can reliably be prevented. CONSTITUTION:A conical internal cylinder 4 is provided at an upstream portion in an external cylinder constituting a combustion chamber, to which secondary air is directly uniformly blown out from a mixing air supply nozzle 2b. The combustion chamber is divided into a combustion region 5 and a secondary air passage 7 through the internal cylinder 4, and a mixing air passage outlet 7a is constructed such that flow velocity of mixing air is 0.8 times or more the flow velocity of combustion gas. Into the combustion region 5, a fuel and an oxydizing agent flow to produce the combustion gas. The oxydizing agent supplied to the secondary air passage 7 cools the internal cylinder 4 uniformly and is fed to a mixing region 6 from the mixing air pasasge outlet 7a. Hereby, the internal cylinder 4 is effectively uniformly cooled with the aid of the secondary air, and simultaneously the internal cylinder 4 is prevented from being burned owing to adhesion of a flame at the secondary air outlet.

    • 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.

    • PURPOSE:To improve strength and durability of a combustion device by provid ing a silicon carbide coating layer in the internal surface of a carbon compound material while a chemical vapor deposition film of carbon in the external sur face of this carbon compound material. CONSTITUTION:A carbon compound material 23, serving as the main unit of a combustion device 11, respectively provides a silicon carbide coating layer 24 in the internal surface of the material 23 and a chemical vapor deposition film 25 of carbon in the external surface. Thus providing sufficient air-tightness in the carbon compound material 23, it surely inhibits high pressure gas from its transmission to the material while remarkably improves its corrosion resis tance. While by covering respectively the internal and external surfaces of the carbon compound material 23 with the fine and hard quality coating layer 24 and the chemical vapor deposition film 25, the carbon compound material 23 enables its existing surface flaw to be completely embedded as well as suffi ciently prevent the generation of a new surface. Further the carbon compound material 23 in its turn the combustor 11 remarkably improves its strength and durability. Here the silicon carbide coating layer 24 can be formed by diffusion, conversion, etc., in addition to coating of silicon carbide.
