Description

Vorrichtung zur Herstellung von ummantelten, geformten Treibsätzen für Raketen Die Herstellung strangförmiger Körper durch plastische Verformung findet vorwiegend mittels Schneckenpressen statt. So werden z. B. zahlreiche Kunststoffe mittels Schneckenpressen verarbeitet, wobei bei der Herstellung endloser Längen ein kontinuierlicher Betrieb gewährleistet ist.Device for the production of coated, shaped propellants for rockets The production of strand-like bodies by plastic deformation takes place predominantly by means of screw presses. So z. B. numerous plastics processed by means of screw presses, with endless lengths in the production continuous operation is guaranteed.

Bei der Herstellung von rauchschwachem Pulver auf Basis Nitrocellulose hat man ebenfalls schon Schneckenpressen verwendet, wobei die Masse zu Streifen und Röhren verformt werden kann.In the production of low-smoke powder based on nitrocellulose screw presses have also been used, whereby the mass is made into strips and tubes can be deformed.

Nitrocellulose findet aber auch als Basis für Treibsätze für Raketen Anwendung. Weiterhin sind Treibmittel für Raketen bekanntgeworden, die aus plastifizierenden Bindemitteln und Oxydationsmitteln bestehen, wobei als plastische Bindemittel Kunststoffe und Kautschuke verwendet werden. Bei der Herstellung von mehrstufigen Raketensätzen, deren Profile über dem Querschnitt von innen nach außen aus zwei oder mehr Stufen bestehen, besteht die Schwierigkeit, diese Stufen homogen aufeinanderzubringen, damit jede Unregelmäßigkeit vermieden wird.Nitrocellulose is also used as the basis for propellants for rockets Use. Furthermore, propellants for rockets have become known that consist of plasticizing There are binders and oxidizing agents, with plastics being the plastic binders and rubbers can be used. In the manufacture of multi-stage rocket sets, their profiles over the cross-section from the inside to the outside of two or more stages exist, there is the difficulty of bringing these stages together homogeneously, so that any irregularity is avoided.

Es wurde nun gefunden, daß man derartige Mehrstufen-Treibsätze kontinuierlich herstellen kann, wenn man hierzu eine Kombination von mehreren Schneckenpressen benutzt. Die Grundbedingung hierbei ist, daß das zuerst gebildete Treibstoffprofil mittels dieser Schneckenkombination kontinuierlich ummantelt wird, wobei das gesamte Profil aus der Formgebungsmatrize austritt.It has now been found that such multi-stage propellant charges can be used continuously can be produced if you use a combination of several screw presses used. The basic requirement here is that the fuel profile formed first is continuously sheathed by means of this screw combination, the entire Profile emerges from the shaping die.

Fig. I zeigt z. B. eine Vorrichtung, bei der Innenkern und Ummantelung des - Treibstoffprofils gleichzeitig hergestellt werden. Die Vorrichtung besteht aus dem feststehenden Schneckendorn 1 mit eingeschraubter Innendüse 2. Um den feststehenden Dorn 1 läuft die Schneckenhohlspindel 3, die innen und außen die Gewindegänge 4 besitzt. Diese Hohlspindel 3 wird von dem Außenzylinder 5 umschlossen, der mit der Außendüse 6 verbunden ist. Durch den zweiteiligen Einfülltrichter 7 werden die Treibsatzmischungen der Schneckenpresse zugeführt. Die Hohlspindel 3 ist mit Durchbrüchen 8 versehen, so daß die Masse in das Innere der Hohlspindel gelangen kann. Innerhalb des Dornes 1 befindet sich das Doppelrohrsystem 9, wodurch eine Heizung bzw. Kühlung möglich ist. Der Außenzylinder 5 besitzt weiterhin die Heiz- und Kühlkanäle 10. Fig. I shows e.g. B. a device in which the inner core and casing of the - fuel profile are produced at the same time. The device consists of the fixed screw mandrel 1 with a screwed-in inner nozzle 2. The hollow screw spindle 3, which has internal and external threads 4, runs around the fixed mandrel 1. This hollow spindle 3 is enclosed by the outer cylinder 5, which is connected to the outer nozzle 6. The propellant charge mixtures are fed to the screw press through the two-part hopper 7. The hollow spindle 3 is provided with openings 8 so that the mass can get into the interior of the hollow spindle. The double pipe system 9 is located inside the mandrel 1, whereby heating or cooling is possible. The outer cylinder 5 also has the heating and cooling channels 10.

Fig.II zeigt eine andere Vorrichtung, mit deren Hilfe derartig ummantelte Treibsatzprofile hergestellt werden können. Hierbei haben zwei bzw. mehrere Schneckenpressen einen gemeinsamen Spritzkopf. Das Kernprofil kann aber auch schon mittels einer Schneckenpresse hergestellt werden und kontinuierlich zwecks weiterer Ummantelung in den Spritzkopf eingeführt werden. Der Spritzkopf besteht aus dem Spritzkopfgehäuse 11 und der inneren Formdüse 12. Die äußere Formgebung des extrudierten Profils wird mittels Zentrierringes 13 festgelegt. Der Zentrierring 13 wird durch den Haltering 14 gehalten. Die Masse des Kernprofils gelangt von der ersten Schneckenpresse in die Innendüse 12, während die Masse der Ummantelung von der zweiten Schneckenpresse durch die Eintrittsöffnung 15 ins Spritzkopfgehäuse 11 gelangt. Das Spritzkopfgehäuse 11 ist mit Heiz-bzw. Kühlkanälen 16 versehen.Fig.II shows another device with the help of such encased Propellant profiles can be produced. Here have two or more screw presses a common spray head. The core profile can also be done by means of a Screw press are manufactured and continuously for the purpose of further jacketing be introduced into the spray head. The spray head consists of the spray head housing 11 and the inner die 12. The outer shape of the extruded profile is set by means of centering ring 13. The centering ring 13 is through the retaining ring 14 held. The mass of the core profile comes in from the first screw press the inner nozzle 12, while the bulk of the casing from the second screw press passes through the inlet opening 15 into the spray head housing 11. The spray head housing 11 is with heating or. Cooling channels 16 provided.

Fig. III zeigt in a und bim Querschnitt zwei Profile mehrstufiger Treibsätze. Um das Kernprofil 17 sind die erste Ummantelung 18 und die zweite Ummantelung 19 angebracht.Fig. III shows in a and b in cross section two multi-stage profiles Propellants. The first casing 18 and the second casing are around the core profile 17 19 attached.

Auf diese Weise lassen sich zwei oder mehrstufige Treib.satzprofile kontinuierlich herstellen, deren Abbrandgeschwindigkeiten je nach Verwendungszweck beliebig variiert werden können.In this way, two or more stage propellant charge profiles can be created continuously produce their burn rates depending on the intended use can be varied as required.
