Description
Stand der TechnikState of the art
Für viele Raumfahrtsanwendungen ist es erforderlich, dass nach abgeschlossener wissenschaftlicher oder technischer Mission ein koordinierter Rückflug der Raumfahrtssonde oder Rakete erfolgt. Die Hauptschwierigkeiten liegen in der Beherrschung der Probleme beim Wiedereindringen in die Erdatmosphäre. Der eindringende Körper muss eine stromlinienförmige, glatte, hitzefeste Oberfläche ohne wesentliche Vorsprünge oder Vertiefungen haben. Bei Vorhandensein solcher Vorsprünge und Vertiefungen kommt es an diesen Stellen beim Eindringen in die Erdatmosphäre zu erheblichen Turbulenzen, wodurch eine systematisch gesteuerte Führung des entsprechenden Flugkörpers nicht mehr möglich ist.For many Space applications require that after completion scientific or technical mission a coordinated return flight of the Space probe or rocket takes place. The main difficulties lie in mastering the problems of reentering the earth's atmosphere. Of the invading bodies must have a streamlined, smooth, heat-resistant surface without significant protrusions or depressions. In the presence of such projections and Recesses occur at these sites when entering the earth's atmosphere to considerable Turbulence, whereby a systematically controlled leadership of the corresponding missile not possible anymore is.
Für viele wissenschaftlich-technische Anwendungen bei Raumfahrtsmissionen, ist es aber erforderlich, dass bestimmte Sensoren im Messeinsatz nicht durch die Außenhaut der Sonde oder Rakete verdeckt sind. Beim Einsatz von optischen Sensoren ist es zwingend notwendig, dass die zu messende Strahlung, während der Messphase, im gesamten Blickfeld (field of view) des Sensors ungehindert einfällt. Das erfordert einen entsprechenden Durchbruch in der Außenhaut der Sonde, der aber während des Durchfluges durch die Atmosphäre so verschlossen sein muss, dass er die Flugeigenschaften der Sonde oder Rakete während des Durchfluges durch die Atmosphäre nicht beeinflusst.For many scientific-technical applications for space missions, However, it is necessary that certain sensors in the measuring insert not through the outer skin the probe or missile are obscured. When using optical Sensors, it is imperative that the radiation to be measured, while the measuring phase, in the entire field of view of the sensor unimpeded. This requires a corresponding breakthrough in the outer skin the probe, but during the passage through the atmosphere must be so closed that the flight characteristics of the probe or rocket during the Flight through the atmosphere unaffected.
Eine bewährte Methode besteht darin, dass die Außenhülle des Flugkörpers ein Fenster eingesetzt bekommt, das bündig mit der Außenoberfläche abschließt und dessen Transmissionseigenschaften die Gewinnung der erforderlichen Messdaten zulässt und auch die notwendigen mechanischen Eigenschaften hat.A proven Method is that the outer shell of the missile a Window gets inserted, which is flush with the outer surface and whose Transmission properties the acquisition of the required measurement data allows and also has the necessary mechanical properties.
Bei einer Vielzahl von Messaufgaben lassen sich Fenster nicht einsetzen, weil diese entweder die zu messenden Größen zu stark verfälschen oder deren Messung nicht ermöglichen.at a multitude of measuring tasks can not be used windows, because they either falsify the quantities to be measured too much or their measurement does not allow.
Zur Abhilfe dieses Mangels wird eine Lösung vorgeschlagen, die es gestattet, dass beim Durchgang durch die Erdatmosphäre der notwendige Durchlass für den Betrieb des Sensors in Form einer Abdeckung mit der äußeren Oberfläche der Sonde oder Rakete glatt und bündig abschließt.to Remedy of this deficiency is proposed a solution that it allows, when passing through the earth's atmosphere, the necessary passage for the Operation of the sensor in the form of a cover with the outer surface of the Probe or rocket smooth and flush concludes.
Zum Messzeitpunkt wird die Abdeckung über ein Kommando so verschoben, dass das Blickfeld des Sensors vollkommen freigelegt wird. Vor dem Wiedereindringen der Sonde in die Atmosphäre wird durch ein weiteres Kommando die Abdeckung wieder in die Ausgangsposition gebracht, d. h. die Abdeckung ist wieder glatt in die äußere Hülle der Sonde oder Rakete eingefügt und verursacht damit keine besonderen Turbulenzen. Ein wichtiger Aspekt für eine Lösung mit einer wiederverschließbaren Klappe besteht noch darin, dass dieses erneute Verschließen mit sehr hoher Zuverlässigkeit erfolgen muss. Das hat folgenden Grund, wenn die Verschlussklappe nicht öffnet, kann die Messung mit dem dahinter angeordneten Sensor nicht durchgeführt werden. Wenn sich aber die geöffnete Verschlussklappe nicht wieder zu schließen ist, lässt sich wegen der Turbolenzen nach Eintritt in die Atmosphäre die rückkehrende Sonde oder Rakete nicht mehr korrekt steuern, wobei dann mit hoher Wahrscheinlichkeit alle Messergebnisse der Mission verloren sind.To the At the time of measurement, the cover is shifted by a command, that the field of view of the sensor is completely exposed. Before reentering the probe into the atmosphere is replaced by another command the cover back to the starting position brought, d. H. the cover is smooth again in the outer shell of the Probe or rocket inserted and causes no special turbulence. An important Aspect for one solution with a resealable Flap still is that this re-closing with very high reliability must be done. This has the following reason, if the flap not open, the measurement with the sensor arranged behind it can not be carried out. If but the open one Closure flap can not be closed again, can be due to the turbulence after entering the atmosphere the returning one No longer correctly control the probe or rocket, and then with high Probability all measurement results of the mission are lost.
