Abstract

The invention relates to a grooved profile for diverting liquid, said profile being placed above the door of an aircraft, wherein the grooved profile extends along the entire width of the door opening and is connected to the fuselage and the liquid collected from the grooved profile can be diverted next to the door opening. The invention aims at improving a grooved profile in such a way that flow resistance arising during flights is further reduced. This is achieved in that the grooved profile (3, 30) is placed behind the outside plating (6) of the door (2) in a dead space (11) between the top edge of the door (2) and a frame (4) guided above the door opening when the door (2) is in closed position.

Description

Rinnenprofil zur Ableitung von Flüssigkeit Channel profile for draining liquid
Die Erfindung betrifft ein Rinnenprofil zur Ableitung von Flüssigkeit, oberhalb einer Tür eines Luftfahrzeuges angeordnet, wobei das Rinnenprofil sich über die Breite der Türöffnung erstreckt und mit dem Rumpf des Luftfahrzeuges verbunden ist und von dem Rinnenprofil aufgefangene Flüssigkeit neben die Türöffnung ableitbar ist.The invention relates to a channel profile for draining liquid, arranged above a door of an aircraft, the channel profile extending across the width of the door opening and being connected to the fuselage of the aircraft and liquid collected from the channel profile being able to be discharged next to the door opening.
Bei heutigen Luftfahrzeugen ist es üblich, oberhalb der Türöffnung ein Rinnenprofil fest auf dem Rumpf anzubringen. Dieses Rinnenprofil dient zur Ableitung von Flüssigkeit, die oberhalb des Rinnenprofils auf den Rumpf fällt und nach unten abfließt. Das Rinnenprofil erstreckt sich deshalb über die Breite der Türöffnung, um die abfließende Flüssigkeit aufzufangen und neben die Türöffnung abzuleiten. Diese Ableitung der Flüssigkeit oberhalb der Türöffnung wird immer dann erforderlich, wenn das stehende Luftfahrzeug einem atmosphärischen Regen ausgesetzt ist oder auf das Luftfahrzeug gesprühte flüssige Chemikalien beispielsweise zur Vermeidung von Eisansatz abzuleiten sind. DasIn today's aircraft, it is common to attach a channel profile firmly to the fuselage above the door opening. This channel profile is used to drain liquid that falls onto the fuselage above the channel profile and flows downwards. The channel profile therefore extends across the width of the door opening in order to catch the flowing liquid and drain it off next to the door opening. This drainage of the liquid above the door opening is always necessary when the stationary aircraft is exposed to atmospheric rain or liquid chemicals sprayed onto the aircraft are to be discharged, for example to avoid ice build-up. The
Rinnenprofil verhindert, daß die abfließende Flüssigkeit in die Türöffnung gelangt oder in der Türöffnung befindliche Personen trifft. Das ist insbesondere bei Flugzeugen bekannt.Channel profile prevents the flowing liquid from entering the door opening or hitting people in the door opening. This is particularly well known for aircraft.
Dieses Profil ist zwar dünn, aber sehr lang, weil es mindestens über die gesamte Breite der Tür reichen muß. Damit stellt das Rinnenprofil im Flugbetrieb eine der wesentlichen Störungen des sonst aerodynamisch glatten Rumpfes dar.This profile is thin, but very long because it must extend at least across the entire width of the door. The channel profile during flight operations is one of the main disorders of the otherwise aerodynamically smooth fuselage.
Das Rinnenprofil wird im wesentlichen in Richtung der um den Rumpf strömenden Luftströmung angeordnet. Aufgrund der zumindest im vorderen Rumpfbereich über die Grenzschicht hinausragenden Höhe des Rinnenprofils und den variablenThe channel profile is arranged essentially in the direction of the air flow flowing around the fuselage. Because of the height of the channel profile and the variable profile, at least in the front fuselage area
Anströmverhältnissen beim Reiseflug gelingt es nur näherungsweise, die Richtung der Luftströmung zu erreichen. Das Rinnenprofil stellt einen aerodynamischen Widerstand dar. Folglich ist eine Störung der Luftströmung entlang des Rumpfes und damit ein zusätzlicher Strömungswiderstand nicht zu vermeiden.The inflow conditions when cruising are only able to approximately achieve the direction of the air flow. The channel profile represents an aerodynamic resistance. Consequently, a disturbance of the air flow along the fuselage and thus an additional flow resistance cannot be avoided.
Aufgabe der Erfindung ist es ein Rinnenprofil so zu verbessern, daß der entstehende Strömungswiderstand im Flugbetrieb eines Luftfahrzeuges weiter reduzierbar ist. Die Aufgabe wird dadurch gelöst, daß das Rinnenprofil bei Schließstellung der Tür hinter der Außenbeplankung der Tür in einem Totraum zwischen Oberkante der Tür und einem oberhalb der Türöffnung geführten Rahmen angeordnet ist. Im Flugbetrieb ergibt sich somit der Vorteil, daß der bisherige Strömungswiderstand des Rinnenprofils bei Luftfahrzeugen grundsätzlich beseitigt ist. Die Erfindung ist bei allen Arten von Luftfahrzeugen, insbesondere Flugzeugen und Drehflüglern, anwendbar.The object of the invention is to improve a channel profile so that the resulting flow resistance during flight operations of an aircraft can be further reduced. The object is achieved in that the channel profile is arranged behind the outer paneling of the door in a dead space between the upper edge of the door and a frame guided above the door opening when the door is in the closed position. In flight operation, there is the advantage that the previous flow resistance of the channel profile in aircraft is basically eliminated. The invention is applicable to all types of aircraft, in particular aircraft and rotary-wing aircraft.
Nach einer Ausgestaltung der Erfindung ist das Rinnenprofil auf einer Rahmenblende befestigt zwischen einer unter der Kontur der Außenwandung liegendenAccording to one embodiment of the invention, the channel profile is fastened to a frame panel between one lying below the contour of the outer wall
Verriegelungsposition, die mit der Schließstellung der Tür erreicht ist und einer Entriegelungsposition, die bei Öffnungsstellung der Tür erreichbar ist, bewegbar. In der Verriegelungsposition und in der Entriegelungsposition ist das Rinnenprofil arretierbar. Es wird somit erreicht, daß bei Öffnung der Tür d.h. bereits mit Anheben der Tür und noch vor dem Schwenken der Tür das Rinnenprofil arbeitsfähig ist und oberhalb der Türöffnung abgeleitete Flüssigkeit auffangbar und neben die Türöffnung ableitbar ist. Vorteilhafterweise kann die vom Rinnenprofil abgeleitete Flüssigkeit auf ein rahmenseitiges Dichtprofil geführt werden und von dort auf die unterhalb der Türöffnung liegende Außenwandung abgeleitet werden.Locking position which is reached with the door in the closed position and an unlocking position which can be reached when the door is in the open position. The channel profile can be locked in the locking position and in the unlocking position. It is thus achieved that when the door is opened i.e. the channel profile is already operational when the door is raised and before the door is pivoted, and any liquid drained above the door opening can be collected and drained off next to the door opening. Advantageously, the liquid derived from the channel profile can be guided to a frame-side sealing profile and from there to the outer wall located below the door opening.
Das Rinnenprofil ist durch die Außenbeplankung gegen die Kraft eines Federmittels unter der Außenwandung des Rumpfes arretierbar. Das Federmittel befindet sich in Eingriff mit einem Führungsmittel, welches das Rinnenprofil führt.The channel profile can be locked against the force of a spring means under the outer wall of the fuselage thanks to the outer paneling. The spring means is in engagement with a guide means which guides the channel profile.

Figur 1 zeigt nach dem Stand der Technik den Ausschnitt einer Ansicht der Außenwandung 1 eines Flugzeugrumpfes mit geschlossener Tür 2 und einem starren Rinnenprofil 3 oberhalb der Tür. Das Rinnenprofil 3 stellt einen zusätzlichen Strömungswiderstand dar. Solche Störungen der Luftströmung entlang des Rumpfes erzeugen eine Wirbelbildung und verhindern eine ungestörte Grenzschicht. Sie sind damit eine nicht unwesentliche Geräuschquelle.According to the prior art, FIG. 1 shows a section of a view of the outer wall 1 of an aircraft fuselage with the door 2 closed and a rigid channel profile 3 above the door. The channel profile 3 represents an additional flow resistance. Such disturbances of the air flow along the fuselage create a vortex formation and prevent an undisturbed boundary layer. This makes them a not insignificant source of noise.
Die Erfindung wird anhand der nachfolgenden Figuren 2 bis 4 erläutert.The invention is explained on the basis of the following FIGS. 2 to 4.
Figur 2 zeigt die Schließstellung der Tür 2. Die Außenbeplankung 6 der Tür 2 bildet im wesentlichen eine geschlossene Kontur mit der Außenwandung 8 des Rumpfes. Es ist erkennbar, daß die Tür 2, dort wo die Außenbeplankung 6 der Tür endet, eine Blende 12 aufgesetzt hat. Diese Blende 12 ist an der Außenbeplankung 6 der Tür 2 befestigt. Die Blende 12 kann fertigungstechnisch auch eine Verlängerung der Außenbeplankung 6 sein. An der Innenseite der Außenbeplankung 6 ist eine türseitige Dichtung 7 angeordnet, die die Tür 2 in Umfangsrichtung umfaßt. Die Dichtung 7 liegt an einem rahmenseitigen Dichtprofil 13 auf, welches auf einer Rahmenblende 5 montiert ist. Die Rahmenblende 5 ist am Türrahmen 4 befestigt. Türseitige Dichtung 7 und rahmenseitiges Dichtprofil 13 bilden einen hermetischen Abschluß des Rumpfinnenraumes gegenüber der äußeren Atmosphäre. Das Rinnenprofil ist in einem Totraum 1 1 angeordnet, der vorhanden ist zwischen oberer Rahmenblende 5, türseitiger Dichtung 7 und Türblende 12. In diesem Totraum 1 1 wird das Rinnenprofil 3 in Verriegelungsposition gehalten.Figure 2 shows the closed position of the door 2. The outer paneling 6 of the door 2 essentially forms a closed contour with the outer wall 8 of the fuselage. It can be seen that the door 2, where the outer paneling 6 of the door ends, has a panel 12. This panel 12 is attached to the outer paneling 6 of the door 2. In terms of production technology, the panel 12 can also be an extension of the outer paneling 6. On the inside of the outer paneling 6, a door-side seal 7 is arranged, which surrounds the door 2 in the circumferential direction. The seal 7 rests on a frame-side sealing profile 13 which is mounted on a frame panel 5. The frame panel 5 is attached to the door frame 4. Door-side seal 7 and frame-side sealing profile 13 form a hermetic seal of the fuselage interior from the outside atmosphere. The channel profile is arranged in a dead space 1 1, which is present between the upper frame panel 5, the door-side seal 7 and the door panel 12. In this dead space 11, the channel profile 3 is held in the locking position.
Das Rinnenprofil 3 befindet sich in Eingriff mit einem auf der Rahmenblende 5 montierten Führungsmittel 14. Am Führungsmittel 14 stützt sich ein Federmittel 10 gegenüber dem Rinnenprofil 3 ab. Gegen die Kraft des Federmittels 10 wird das Rinnenprofil 3 durch die als Anschlag wirkende Türblende 12 in Verriegelungsposition arretiert. Das Rinnenprofil 3 ist vorteilhafterweise nicht mehr auf der Außenwandung 8 des Rumpfes angeordnet, so daß die Nachteile des Standes der Technik entfallen. Die Verriegelungsposition des Rillenprofils 3 wird grundsätzlich in Schließstellung der Tür 2 (geschlossener Zustand) erreicht. Das Rillenprofil fängt die Flüssigkeit mit einem im wesentlichen U-förmig gestalteten Profil.The channel profile 3 is in engagement with a guide means 14 mounted on the frame panel 5. A spring means 10 is supported on the guide means 14 opposite the Channel profile 3 from. Against the force of the spring means 10, the channel profile 3 is locked in the locking position by the door panel 12 acting as a stop. The channel profile 3 is advantageously no longer arranged on the outer wall 8 of the fuselage, so that the disadvantages of the prior art are eliminated. The locking position of the groove profile 3 is basically reached in the closed position of the door 2 (closed state). The groove profile captures the liquid with an essentially U-shaped profile.
Figur 3 zeigt das Rinnenprofil 3 in Öffnungsstellung der Tür 2. Die Öffnungsstellung der Tür 2 umfaßt das Anheben und/oder Schwenken der Tür 2. Da die in Figur 3 erreichte Entriegelungsposition des Rinnenprofils 3 bereits im Bewegungsschritt des Anhebens der Tür 2 erfolgt und dieser Schritt bereits zum Zustand des öffnens der Tür gehört, wird nachfolgend aus Gründen der Vereinfachung lediglich von Öffnungsstellung der Tür gesprochen.Figure 3 shows the channel profile 3 in the open position of the door 2. The open position of the door 2 includes lifting and / or pivoting the door 2. Since the unlocking position of the channel profile 3 reached in Figure 3 already takes place in the moving step of lifting the door 2 and this step Already belongs to the state of the opening of the door, for reasons of simplification, only the opening position of the door is referred to below.
Bereits beim ersten Schritt der Öffnungsstellung, dem Anheben der Tür, bewegt das Federmittel 10, aufgrund der gespeicherten kinetischen Energie, das Rinnenprofil 3 entlang dem Weg des Führungsmittels 14 in die Entriegelungsposition. Bereits jetzt wird ablaufende Flüssigkeit von der Außenwandung 8 des Rumpfes durch das Rillenprofil 3 erfaßt und abgeleitet. Die Ableitung der Flüssigkeit kann vorteilhaft auf das bereits vorhandene, rahmenseitige Dichtprofil 13 erfolgen. Vom Dichtprofil 13 kann die Weiterleitung neben die Türöffnung auf die äußere, untere Rumpfwandlung erfolgen.Already in the first step of the opening position, the lifting of the door, the spring means 10, due to the stored kinetic energy, moves the channel profile 3 along the path of the guide means 14 into the unlocking position. Already running liquid is detected and drained from the outer wall 8 of the fuselage through the groove profile 3. The liquid can advantageously be drained off onto the already existing, frame-side sealing profile 13. From the sealing profile 13, the forwarding can take place next to the door opening to the outer, lower fuselage wall.
Der weitere Schritt des Schwenkens der Tür beim Öffnungsvorgang läßt die bereits erreichte Entriegelungsposition des Rinnenprofils 3 unberührt. In der Entriegelungsposition kann das Rinnenprofil 3 etwas außerhalb der Kontur der Außenwandung 8 arretiert sein. Eine Arretierung des Rinnenprofils 3 wird durch die auf einen an der Außenwandung 8 innen liegenden Anschlag 9 treffende Rinnennase 15 erreicht.The further step of pivoting the door during the opening process does not affect the unlocking position of the channel profile 3 that has already been reached. In the unlocked position, the channel profile 3 can be locked somewhat outside the contour of the outer wall 8. The channel profile 3 is locked in place by the channel nose 15 hitting a stop 9 located on the inside of the outer wall 8.
Figur 4 zeigt ausschnittsweise und schematisch wie im Rinnenprofil 30 gesammelte Flüssigkeit auf das rahmenseitige Dichtprofil 130 ablaufen kann. Das Rinnenprofil 30 befindet sich in Entriegelungsposition. Die Tür 2 ist nicht gezeigt. Am unteren Ende des rahmenseitigen Dichtprofils 130 (nicht dargestellt) wird die Flüssigkeit wieder auf die Außenwandung 8 des Rumpfes geleitet. In einer weiteren vorteilhaften Ausgestaltung kann das Federmittel 10 aktiv von einer Antriebseinheit (nicht dargestellt) gesteuert werden. Die Antriebseinheit könnte die Bewegung des Federmittels elektrisch, pneumatisch oder hydraulisch steuern. Die Bewegung ist nur notwending für das Erreichen derFIG. 4 shows sections and schematically how liquid collected in the channel profile 30 can run off onto the frame-side sealing profile 130. The channel profile 30 is in the unlocked position. The door 2 is not shown. At the bottom of the frame-side sealing profile 130 (not shown), the liquid is directed back onto the outer wall 8 of the fuselage. In a further advantageous embodiment, the spring means 10 can be actively controlled by a drive unit (not shown). The drive unit could control the movement of the spring means electrically, pneumatically or hydraulically. The movement is only necessary for reaching the
Entriegelungsposition. Die Rückstellung des Rinnenprofils 3 in die Verriegelungsposition könnte durch die mit dem Rinnenprofil in Anschlag zu bringende Türblende 12 erfolgen.Unlocking position. The resetting of the channel profile 3 into the locking position could take place through the door panel 12 to be brought into contact with the channel profile.
Eine weitere Ausgestaltung sieht vor, die Profilrinne 30 zugleich zur Verbesserung der Abdichtung der Tür auszunutzen. Die Rinne 30 ist in einem solchen Fall vorzugsweise aus einem elastischen Material gefertigt.A further embodiment provides that the profile channel 30 is also used to improve the sealing of the door. In such a case, the channel 30 is preferably made of an elastic material.
Die Rinne 30 könnte auch aus mehreren Teilen bestehen, die eventuell rechts und links ausklappbar sind, um die seitliche Dichtung zu verbessern. The channel 30 could also consist of several parts, which can possibly be folded out to the right and left, in order to improve the side seal.
