Description
Das Hauptpatent 2219 370 betrifft ein Verfahren zur Herstellung eines stranggepreßten Raketentreibstoffes auf der Basis von Ammonium-' oder Kaliumperchlorat, Aluminium oder Magnesium sowie Silikonkautschuk als Bindemittel, der durch das Mundstück einer Kolbenoder Schneckenpresse, das der gewünschten Treibsatz-Konfiguration entspricht, verpreßt wird, wobei gemäß dem Haupipatent 2219 370 als Bindemittel ein heißvulkanisierender Silikonkautschuk verwendet und der aus dem Mundstück austretende geformte Treibsatz durch induktive Heizung über die Vulkanisation des Silikonkautschuks gehärtet wird. Dieses Verfahren ermöglicht eine wesentliche Verbesserung und Vereinfachung der Herstellung von Raketentreibsätzen. Es eignet sich — wie beschrieben — im wesentlichen zur Herstellung von Komposittreibsf offen, dieThe main patent 22 19 370 relates to a process for the production of an extruded rocket fuel on the basis of ammonium or potassium perchlorate, aluminum or magnesium and silicone rubber as a binding agent, which is pressed through the mouthpiece of a piston or screw press, which corresponds to the desired propellant configuration, whereby, according to the main patent 2219 370, a hot-vulcanizing silicone rubber is used as the binding agent and the shaped propellant emerging from the mouthpiece is hardened by inductive heating via the vulcanization of the silicone rubber. This method enables a significant improvement and simplification of the manufacture of rocket propellants. It is suitable - as described - essentially for the production of Komposittreibsf open, the

Erfindungsgemäß wird vorgeschlagen, daß der Treibsatzmischung vor der Formung und Aushärtung
flammenfärbende Salze zugemischt werden. Danach können also die Flammen solcher Raketentreibstoffe
durch Zugabe von Alkali- oder Erdalkalisalzen angefärbt werden, ohne daß dadurch das beschriebene
Herstellungsverfahren beeinflußt wird. Als flammenfärbende Zusätze eignen sich dabei sowohl solche Salze,
die keinen oxidierenden Sauerstoff enthalten, wie Chloride, Sulfate, Oxalate oder Tartrate (z.B. Strontiumoxalat,
Bariumchlorid, Natriumtartrat), als auch solche, die überschüssigen Sauerstoff enthalten, wie
Nitrate, Perchlorate, Chlorate (z. B. Lithiumperchlorat, Natriumperchlorat, Bariumnitrat u. ä.). Im letzteren Fall

ίο Zur Herstellung der erfinduÄgsgfemäßen Pulverrohmasse
kann nach folgenden Beispielen verfahren werden:According to the invention it is proposed that the propellant mixture be admixed with flame-coloring salts prior to shaping and curing. Thereafter, the flames of such rocket propellants can be colored by adding alkali or alkaline earth salts without affecting the manufacturing process described. Salts that do not contain oxidizing oxygen, such as chlorides, sulfates, oxalates or tartrates (e.g. strontium oxalate, barium chloride, sodium tartrate), and those that contain excess oxygen, such as nitrates, perchlorates, chlorates (e.g. B. lithium perchlorate, sodium perchlorate, barium nitrate and the like). In the latter case, depending on the amount in which these substances are added, the amount of oxidizer in the mixture can be reduced, ^ f
ίο The following examples can be used to produce the raw powder mass according to the invention:

Die so erzeugten Rohmassen werden in der bereits in der Hauptanmeldung beschriebenen Weise in einen mit einem Spritzmundstück versehenen Zylinder gegeben und mit Hilfe eines Kolbens zu Strängen der gewünschten Größe gespritzt, welche beim Passieren eines mikrowellen- oder hochfrequenzerhitzten Tunnelofens durch die Erwärmung gehärtet werden.The raw materials thus produced are in the manner already described in the main application in a with given a die provided cylinder and with the help of a piston to strands of the desired size, which is injected when passing through a microwave or high-frequency heated tunnel oven hardened by the heating.
so Selbstverständlich kann die Verformung der Rohmasse zu Strängen des gewünschten Querschnitts auch mit
Hilfe von Schneckenpressen erfolgen, soweit es die Reibempfindlichkeit der Massen gestattet
Aus den solcherart hergestellten und gehärteten Strängen können durch Ablängen die Treibsätze in der
gewünschten Größe hergestellt werden.So of course, the shaping of the raw mass into strands of the desired cross-section can also be carried out with the aid of screw presses, provided that the masses are sensitive to friction
The propellant charges can be produced in the desired size from the strands produced and hardened in this way by cutting them to length.
