Description
【発明の詳細な説明】 (産業上の利用分野) この発明は、固体ラムロケット用のガス発生剤に関す
る。TECHNICAL FIELD The present invention relates to a gas generating agent for a solid ram rocket.
(従来技術) 固体ラムロケットは、通常、1次燃焼室で金属燃料分の
多いガス発生剤を燃焼させて、ガス化し、この生成ガス
を2次燃焼室へ導いて、2次燃焼室内に取り入れた空気
によって完全燃焼させるものであり、普通のロケットに
比較して、高比推力を得ることができる。(Prior Art) A solid ram rocket normally burns a gas generant containing a large amount of metallic fuel in a primary combustion chamber to gasify it, and then guides this generated gas to the secondary combustion chamber and takes it into the secondary combustion chamber. Since it is completely burned by the air, it is possible to obtain a high specific thrust as compared with an ordinary rocket.
しかしながら、この固体ラムロケットでは、1次燃焼室
から2次燃焼室へ供給される生成ガスが、空気によって
冷却されて、完全燃焼せず、そのままノズルから排出さ
れてしまい、所望の性能を得にくいという問題がある。
この問題を解消しようとして、ガス発生剤への酸化剤の
配合量を多くし、2次燃焼室へ供給される生成ガスの温
度を高めることも試みられているが、酸化剤の配合割合
を多くすると、必然的に金属燃料の割合が低下する。そ
の結果、大部分の金属燃料が1次燃焼室で燃焼してしま
い、2次燃焼室へは、燃料が少なく酸化物の多い生成ガ
スが流入し、ラムロケット本来の性能を発揮することが
できなくなってしまう。However, in this solid ram rocket, the produced gas supplied from the primary combustion chamber to the secondary combustion chamber is cooled by air, does not completely burn, and is discharged from the nozzle as it is, so that it is difficult to obtain desired performance. There is a problem.
In order to solve this problem, it has been attempted to increase the compounding amount of the oxidizer in the gas generating agent and raise the temperature of the produced gas supplied to the secondary combustion chamber, but increase the compounding ratio of the oxidizer in many cases. Then, the proportion of metal fuel inevitably decreases. As a result, most of the metallic fuel burns in the primary combustion chamber, and the produced gas with less fuel and a large amount of oxides flows into the secondary combustion chamber, and the original performance of the ram rocket can be exhibited. It's gone.
これらの欠点を補うようにしたガス発生剤として、例え

られている。As a gas generating agent for compensating for these drawbacks, for example, Journal of Spacecraft & Rocket 1982 4
As shown in the monthly issue, magnarium, which has a relatively low ignition temperature, and boron, which has a high combustion heat, are used as the metal fuel.

まい、生成ガスが2次燃焼室に流入した時、温度が低下
し、空気を付加しても燃焼しなくなってしまう。又、1
次燃焼室で溶融した金属が互いに融着し、これが1次燃
焼室のノズルをチョークするという問題もある。However, even with this conventional gas generating agent, the combustion pressure in the primary combustion chamber can only be set to about 30 kgf / cm 2 at most, and the gas generating agent is originally composed of a small amount of oxidizing agent. Therefore, the combustion of boron in the primary combustion chamber is insufficient and the boron is not heated to a temperature sufficient for complete combustion in the secondary combustion chamber. Further, the energy generated by burning a part of the metal fuel in the primary combustion chamber is relatively large because the metal fuel particles are relatively large (the size of boron particles is 1 to 3 μ, and the size of magnarium particles is 10 μm). ~ 20μ is the limit, it is usually difficult to produce finer particles than this),
The metal fuel particles are consumed due to the temperature rise themselves, and when the produced gas flows into the secondary combustion chamber, the temperature drops, and even if air is added, it will not burn. Again 1
There is also the problem that the molten metals in the secondary combustion chamber fuse together and choke the nozzles of the primary combustion chamber.

A gas generant for solid ram rockets that contains boron, magnalium, or a mixture of both as a metal fuel and has an oxidizer content of 40% or less. The following aluminum powder is blended in an amount of 1 to 3% by weight, and the content of the metal fuel composed of boron, magnalium or a mixture of the two is adjusted.
It is a gas generating agent characterized by being 30 to 50% by weight.

If the particle size of the aluminum powder is larger than 0.1 micron, the combustion efficiency in the primary combustion chamber is reduced, and the temperature of the produced gas flowing into the secondary combustion chamber cannot be kept high, which is an object of the present invention. Cannot be achieved. Aluminum powder having an average particle size of 0.1 micron or less can be produced by a gas evaporation method. The in-gas evaporation method vaporizes aluminum in a high vacuum to solidify the extremely dilute aluminum gas particles, and the aluminum particles are prevented from associating during solidification to increase the particle size, A fine aluminum powder is obtained.

するため、燃料価が低下してしまい不適当である。The blending amount of the aluminum powder needs to be 1 to 3% by weight. If the blending amount is less than 1% by weight, the combustion efficiency in the primary combustion chamber is reduced, the temperature of the produced gas supplied to the secondary combustion chamber cannot be kept high, and a sufficiently satisfactory specific thrust cannot be obtained. . On the other hand, if the blending amount exceeds 3% by weight, the blending ratio of the metal fuel having a high calorific value is reduced accordingly, and the fuel value is lowered, which is not suitable.

ができるという効果を奏し得る。(Operation and Effect of the Invention) Generally, it is said that the physicochemical properties of metal particles change as the particle size decreases. For aluminum,
Usually the melting point is around 700 ℃, but the average particle size is 0.1
Friction heat (around 300 ℃) when the powder becomes less than micron
The surface will melt in a certain degree. Aluminum ignites and burns in the vicinity of this melting surface, and therefore ignites at an extremely low temperature. In this way, the aluminum powder having an average particle size of 0.1 micron or less has a low ignition temperature, and when heat is applied, it is instantly ignited and burned. When aluminum powder is ignited and burnt in the primary combustion chamber, the combustion heat generated at that time efficiently burns the metallic fuel consisting of boron, magnalium, or a mixture of both, and supplies the high-temperature generated gas to the secondary combustion chamber. can do. As a result, it is possible to completely burn the metallic fuel having a high calorific value in the secondary combustion chamber while setting the blending ratio of the metallic fuel to an appropriate range, thereby increasing the specific thrust of the ram rocket and improving its performance. The effect of being able to be made can be produced.
