Description

Die Erfindung bezieht sich auf eine Hydrofoilfinne zur Befestigung an einem Board. Weiterhin bezieht sich die Erfindung auf ein Hydrofoil mit einer Hydrofoilfinne.The invention relates to a hydrofoil fin for attachment to a board. Furthermore, the invention relates to a hydrofoil with a hydrofoil fin.

Hydrofoils ermöglichen es, beim Kitesurfen oder Jetskifahren das Board aus dem Wasser zu heben, um hierdurch den Strömungswiderstand zu verringern. Sie umfassen in der Regel eine Kielfinne, im folgenden auch als Hydrofoilfinne bezeichnet, mit einem ersten Endabschnitt zur Befestigung an dem Board sowie einen vorderen Flügel und einen hinteren Flügel, die in Fahrtrichtung hintereinander liegend angeordnet und mit einem zweiten Endabschnitt der Kielfinne verbunden sind. Wird das Board aus dem Wasser gehoben, bleiben lediglich ein Teil der Hydrofoilfinne und die beiden Flügel in das Wasser eingetaucht. Hierbei können große Biege- und Torsionsmomente an der Hydrofoilfinne auftreten.Hydrofoils make it possible to lift the board out of the water when kitesurfing or jet skiing, thereby reducing the flow resistance. They generally comprise a keel fin, hereinafter also referred to as a hydrofoil fin, with a first end section for attachment to the board and a front wing and a rear wing, which are arranged one behind the other in the direction of travel and are connected to a second end section of the keel fin. If the board is lifted out of the water, only a part of the hydrofoil fin and the two wings remain immersed in the water. Large bending and torsional moments can occur on the hydrofoil fin.

Eine Hydrofoilfinne nach dem Oberbegriff von Patentanspruch 1 ist aus US 3,669,589 bekannt.A hydrofoil fin according to the preamble of claim 1 is from US 3,669,589 known.

Weitere Hydrofoilfinnen sind in WO 87/01345 und US 5,211,594 beschrieben.Other hydrofoil fins are in WO 87/01345 and US 5,211,594 described.

Der Erfindung liegt die Aufgabe zu Grunde, ein Hydrofoilfinne zu schaffen, welche sich bei geringem Bauteilgewicht durch eine hohe Biege- und Torsionssteifigkeit auszeichnet.The invention is based on the object of creating a hydrofoil fin which is distinguished by a high bending and torsional rigidity with a low component weight.

Diese Aufgabe wird durch eine Hydrofoilfinne gemäß Anspruch 1 gelöst. Diese umfasst insbesondere einen Kernbereich aus einer Vielzahl von Torsionskästen und eine den Kernbereich umgebende Außenschale aus mehrlagigem Faserverbundwerkstoff.
Die Torsionskästen weisen Wände aus Faserverbundwerkstoff auf, um eine besonders leichtgewichtige und steife Bauweise zu erzielen. Insbesondere weisen die Torsionskästen jeweils vier Wände aus mehrlagigem Faserverbundwerkstoff auf, welche jeweils parallel zur Längserstreckungsrichtung der Hydrofoilfinne verlaufen. Dabei ist der Faserverlauf in mindestens einer der Lagen des Faserverbundwerkstoffs zu der Längserstreckungsrichtung der Hydrofoilfinne mit einem ersten Winkel angestellt und der Faserverlauf in mindestens einer weiteren der Lagen zu der Längserstreckungsrichtung der Hydrofoilfinne mit einem zweiten Winkel angestellt, so dass sich die jeweiligen Fasern kreuzen.This object is achieved by a hydrofoil fin according to claim 1. This includes in particular a core area made up of a large number of torsion boxes and an outer shell made of multi-layer fiber composite material surrounding the core area.
The torsion boxes have walls made of fiber composite material in order to achieve a particularly lightweight and rigid construction. In particular, the torsion boxes each have four walls made of multi-layer fiber composite material, which each run parallel to the longitudinal direction of the hydrofoil fin. The fiber course in at least one of the layers of the fiber composite material is set at a first angle to the longitudinal direction of the hydrofoil fin, and the fiber course in at least one other of the layers is set at a second angle to the longitudinal direction of the hydrofoil fin, so that the respective fibers cross.

Vorteilhafte Ausgestaltungen sind Gegenstand weiterer Ansprüche.Advantageous refinements are the subject of further claims.

So können Lagen mit positivem und negativem Anstellwinkel zur Längserstreckungsrichtung einander abwechselnd angeordnet sein.Layers with a positive and negative angle of attack relative to the longitudinal direction can be arranged alternately.

Im Hinblick auf ein besonders geringes Bauteilgewicht können die Torsionskästen als Hohlkammern ausgebildet werden. Es ist jedoch auch möglich, mit einem Schaumstoff gefüllte Torsionskästen zu verwenden.With regard to a particularly low component weight, the torsion boxes can be designed as hollow chambers. However, it is also possible to use torsion boxes filled with a foam.

Beispielsweise können die Torsionskästen als umwickelte Schaumstoffprofile mit sich kreuzendem Faserverlauf ausgebildet sein. Die Schaumstoffprofile bilden bei der Herstellung gewissermaßen die Kerne für die Wicklungen der Fasern.For example, the torsion boxes can be designed as wrapped foam profiles with a crossing fiber course. The foam profiles form the cores for the winding of the fibers.

Ferner können mindestens zwei Torsionskästen vorgesehen sein, welche in einer Ebene quer zur Längserstreckungsrichtung der Hydrofoilfinne einen unterschiedlichen Querschnitt aufweisen. Dies ermöglicht eine einfache Anpassung an einen strömungsgünstigen Profilquerschnitt der Hydrofoilfinne.Furthermore, at least two torsion boxes can be provided, which have a different cross section in a plane transverse to the longitudinal direction of the hydrofoil fin. This enables simple adaptation to a streamlined profile cross section of the hydrofoil fin.

Gemäß einer weiteren vorteilhaften Ausgestaltung weist die Außenschale aus mehrlagigem Faserverbundwerkstoff mindestens eine Lage mit in Längserstreckungsrichtung der Hydrofoilfinne ausgerichtetem Faserverlauf auf.According to a further advantageous embodiment, the outer shell made of multi-layer fiber composite material has at least one layer with a fiber course oriented in the longitudinal direction of the hydrofoil fin.

Weiterhin kann die Außenschale zusätzliche Lagen aufweisen, deren Faserverläufe zur Längserstreckungsrichtung der Hydrofoilfinne angewinkelt sind und einander kreuzen. Gemäß einer weiteren vorteilhaften Ausgestaltung besitzt die Hydrofoilfinne einen Befestigungsabschnitt zur Ankopplung an ein Board. Dabei erstreckt sich der Kernabschnitt mit den Torsionskästen bis in den Befestigungsabschnitt hinein, um eine optimale Anbindung der Hydrofoilfinne an das Board zu ermöglichen und eine weitere Steigerung der Biege- und Torsionssteifigkeit zu erzielen.Furthermore, the outer shell can have additional layers, the fiber courses of which are angled to the longitudinal direction of the hydrofoil fin and cross each other. According to a further advantageous embodiment, the hydrofoil fin has a fastening section for coupling to a board. The core section with the torsion boxes extends into the fastening section to enable an optimal connection of the hydrofoil fin to the board and to achieve a further increase in bending and torsional rigidity.

Das Ausführungsbeispiel zeigt ein Hydrofoil 1 zur Befestigung an einem Board 2, welches sich zum Kitesurfen und Jetskifahren eignet.The exemplary embodiment shows a hydrofoil 1 for attachment to a board 2, which is suitable for kitesurfing and jet skiing.

Das Hydrofoil 1 umfasst eine Kielfinne, im Folgenden auch Hydrofoilfinne 3, einen Verbindungsstab 4, einen vorderen Flügel 5 und einen hinteren Flügel 6. Diese Komponenten können lösbar miteinander verbunden sein, so dass diese einzelnen ausgetauscht werden können. Es ist jedoch auch möglich, zwei oder mehr der vorgenannten Komponenten in einem einstückigen Bauteil unlösbar miteinander zu vereinen.The hydrofoil 1 comprises a keel fin, hereinafter also a hydrofoil fin 3, a connecting rod 4, a front wing 5 and a rear wing 6. These components can be detachably connected to one another so that these can be replaced. However, it is also possible to combine two or more of the aforementioned components in a one-piece component.

Die Hydrofoilfinne 3 weist einen ersten Endabschnitt 7 zur Befestigung an dem Board 2 sowie einen zweiten Endabschnitt 8 zum Anschluss des Verbindungsstabs 4 auf. Sie ist stab- oder balkenförmig ausgebildet und weist einen stromlinienförmigen Profilquerschnitt (vgl. Fig. 3) auf. Die Hydrofoilfinne 3 besitzt in ihrer Längserstreckungsrichtung A eine Höhe von etwa 400 bis 1200 mm. Der Profilquerschnitt weist eine größte Weite von etwa 5 bis 20 mm und eine Länge in Fahrtrichtung von etwa 50 bis 200 mm auf.The hydrofoil fin 3 has a first end section 7 for attachment to the board 2 and a second end section 8 for connecting the connecting rod 4. It is rod-shaped or bar-shaped and has a streamlined profile cross-section (cf. Fig. 3 ) on. The hydrofoil fin 3 has a height of about 400 to 1200 mm in its longitudinal direction A. The profile cross section has a greatest width of about 5 to 20 mm and a length in the direction of travel of about 50 to 200 mm.

Der erste Endabschnitt 7 kann einen flanschartigen erweiterten Befestigungsabschnitt 9 ausbilden, der eine gegenüber dem restlichen Querschnitt der Hydrofoilfinne 3 erweiterte Auflagefläche für die Unterseite des Boards 2 bildet. Es ist auch möglich, die Hydrofoilfinne 3 durch das Board 2 hindurch zu stecken, so dass der flanschartige Befestigungsabschnitt 9 von oben auf dem Board 3 aufliegt. Ferner ist es möglich, im Board 2 eine Aufnahmeöffnung auszubilden, in welcher ein Endabschnitt 7 der Hydrofoilfinne 3 formschlüssig aufgenommen ist. Eine flanschartige Erweiterung an dem Befestigungsabschnitt 9 kann in diesem Fall auch entfallen.The first end section 7 can form a flange-like extended fastening section 9, which forms a support surface for the underside of the board 2 which is enlarged compared to the remaining cross section of the hydrofoil fin 3. It is also possible to insert the hydrofoil fin 3 through the board 2 so that the flange-like fastening section 9 rests on the board 3 from above. Furthermore, it is possible to form a receiving opening in the board 2, in which an end section 7 of the hydrofoil fin 3 is received in a form-fitting manner. A flange-like expansion on the fastening section 9 can also be omitted in this case.

Der zweite Endabschnitt 8 der Hydrofoilfinne 3 weist eine Aufnahme 10 für den Verbindungsstab 4 auf. Über den Verbindungsstab 4 sind der vordere Flügel 5 und der hintere Flügel 6 an der Hydrofoilfinne 3 befestigt. An den Flügeln 5 und 6 auftretende Kräfte werden über den Verbindungsstab 4 in der Aufnahme 10 gegen die Hydrofoilfinne 3 abgestützt.The second end section 8 of the hydrofoil fin 3 has a receptacle 10 for the connecting rod 4. The front wing 5 and the rear wing 6 are fastened to the hydrofoil fin 3 via the connecting rod 4. Forces occurring on the wings 5 and 6 are supported against the hydrofoil fin 3 via the connecting rod 4 in the receptacle 10.

Im Hinblick auf eine hohe Biege- und Torsionssteifigkeit sowie ein geringes Bauteilgewicht weist die Hydrofoilfinne 3 einen sehr leichtgewichtigen, gleichwohl steifen Kernbereich 11 auf, welcher von einer Außenschale 12 aus mehrlagigem Faserverbundwerkstoff, beispielsweise kohlefaserverstärktem Kunststoff (CFK) oder glasfaserverstärktem Kunststoff (GFK), umgeben ist. Die Außenschale 12 ermöglicht insbesondere eine strömungsgünstige Ausgestaltung des Profilquerschnitts wie in Figur 3 dargestellt.With regard to a high bending and torsional rigidity and a low component weight, the hydrofoil fin 3 has a very light, yet stiff core area 11, which is surrounded by an outer shell 12 made of multi-layer fiber composite material, for example carbon fiber reinforced plastic (CFRP) or glass fiber reinforced plastic (GFK) is. The outer shell 12 enables, in particular, a streamlined configuration of the profile cross section as in FIG Figure 3 shown.

Der Kernbereich 11 der Hydrofoilfinne 3 besteht aus einer Vielzahl von Torsionskästen 13, welche der Hydrofoilfinne 3 eine hohe Steifigkeit verleihen. Diese Torsionskästen 13 weisen jeweils Wände aus mehrlagigem Faserverbundwerkstoff, insbesondere kohlefaserverstärktem Kunststoff (CFK) oder glasfaserverstärktem Kunststoff (GFK), auf. Wie die Figuren 3 und 4 zeigen, sind die Torsionskästen 13 derart angeordnet, dass jeweils vier Wände 14 eines solchen Torsionskastens 13 parallel zur Längserstreckungsrichtung A der Hydrofoilfinne 3 verlaufen. Die Anzahl der Torsionskästen kann gegebenenfalls auch auf einen einzigen Torsionskasten reduziert werden. Eine größere Anzahl ist jedoch für eine hohe Biege- und Torsionssteifigkeit besser geeignet.The core area 11 of the hydrofoil fin 3 consists of a large number of torsion boxes 13, which give the hydrofoil fin 3 a high degree of rigidity. These torsion boxes 13 each have walls made of multi-layer fiber composite material, in particular carbon fiber reinforced plastic (CFRP) or glass fiber reinforced plastic (GFK). As the Figures 3 and 4 show, the torsion boxes 13 are arranged such that four walls 14 of such a torsion box 13 each run parallel to the longitudinal direction of extension A of the hydrofoil fin 3. If necessary, the number of torsion boxes can also be reduced to a single torsion box. However, a larger number is more suitable for high bending and torsional rigidity.

Figur 5 zeigt einen einzelnen Torsionskasten 13 mit vier einander jeweils paarweise gegenüberliegenden Wänden 14. Dieser kann gegebenenfalls durch weitere Wände 15 in Längserstreckungsrichtung A geschlossen sein. Figure 5 shows a single torsion box 13 with four walls 14 opposite each other in pairs. This can optionally be closed by further walls 15 in the longitudinal direction A.

Zumindest die zur Längserstreckungsrichtung A parallelen Wände 14 weisen jeweils mindestens eine Lage mit einem Faserverlauf 16 auf, der zu der Längserstreckungsrichtung A der Hydrofoilfinne 3 mit einen ersten Winkel α1 von vorzugsweise 45° angestellt ist. Der Faserverlauf 17 in mindestens einer weiteren der Lagen ist zu der Längserstreckungsrichtung A der Hydrofoilfinne 3 mit einen zweiten Winkel α2 von vorzugsweise -45° angestellt, so dass sich die jeweiligen Fasern kreuzen. Auch die weiteren Wände 15 können Lagen mit sich kreuzendem Faserverlauf aufweisen.At least the walls 14, which are parallel to the longitudinal direction of extension A, each have at least one layer with a fiber course 16, which is set to the longitudinal direction of extension A of the hydrofoil fin 3 with a first angle α 1 of preferably 45 °. The fiber course 17 in at least one other of the layers is set at a second angle α 2 of preferably -45 ° to the longitudinal direction of extension A of the hydrofoil fin 3, so that the respective fibers cross. The other walls 15 can also have layers with a crossing fiber course.

Dabei können an den Torsionskästen 13 insbesondere Lagen mit positivem und negativem Anstellwinkel α1 und α2 zur Längserstreckungsrichtung A unmittelbar aufeinander folgend und einander abwechselnd angeordnet sein.In this case, in particular layers with positive and negative angles of attack α 1 and α 2 with respect to the longitudinal direction A can be arranged directly one after the other and alternately on the torsion boxes 13.

Die Torsionskästen 13 können jeweils mit einem Schaumstoff 18 gefüllt sein, wie dies in Figur 5 dargestellt ist. Es ist jedoch auch möglich, einige oder alle Torsionskästen 13 als Hohlkammern auszubilden.The torsion boxes 13 can each be filled with a foam 18, as shown in FIG Figure 5 is shown. However, it is also possible to design some or all of the torsion boxes 13 as hollow chambers.

Insbesondere können Torsionskästen 13 als umwickelte Schaumstoffprofile mit sich kreuzendem Faserverlauf ausgebildet werden, wobei das jeweilige Schaumstoffmaterial als Wicklungskern dient.In particular, torsion boxes 13 can be formed as wrapped foam profiles with a crossing fiber course, the respective foam material serving as the winding core.

Im Kernbereich der Hydrofoilfinne 3 sind die Torsionskästen 13 gebündelt angeordnet, so dass sich deren Wände 14, 15 gegeneinander abstützen. Dieses Bündel wird durch die Außenschale 12 umschlossen, welche ihrerseits ebenfalls aus mehrlagigem Faserverbundwerkstoff besteht.The torsion boxes 13 are arranged in bundles in the core area of the hydrofoil fin 3, so that their walls 14, 15 are supported against one another. This bundle is enclosed by the outer shell 12, which in turn also consists of multi-layer fiber composite material.

Figur 3 zeigt lediglich beispielhaft und ohne Beschränkung hierauf eine Anordnung der Torsionskästen in zwei Reihen. Die Anzahl der Reihen kann sowohl kleiner als auch größer gewählt werden. Zudem können Torsionskästen mit unterschiedlichem Querschnitt verwendet werden, um beispielsweise eine bessere Anpassung an einen gewünschten Profilquerschnitt zu erzielen. Grundsätzlich kann auch von einer Anordnung in Reihen abgesehen werden. Figure 3 shows an example of and without restriction to an arrangement of the torsion boxes in two rows. The number of rows can be chosen both smaller and larger. In addition, torsion boxes with different cross-sections can be used, for example to achieve better adaptation to a desired profile cross-section. In principle, an arrangement in rows can also be dispensed with.

Im Unterschied zu den Torsionskästen 13 weist die Außenschale 12 eine oder mehrere Lagen mit einem zur Längserstreckungsrichtung A der Hydrofoilfinne 3 ausgerichtetem Faserverlauf 19 auf, wie dies in Figur 4 angedeutet ist. Zwischen solchen Lagen mit parallelem Faserverlauf 19 zur Längserstreckungsrichtung A können weitere Lagen vorgesehen sein, deren Faserverläufe 20 und 21 zur Längserstreckungsrichtung A angewinkelt sind, beispielsweise mit +/- 45°, und einander kreuzen.In contrast to the torsion boxes 13, the outer shell 12 has one or more layers with a fiber course 19 aligned with the longitudinal extension direction A of the hydrofoil fin 3, as shown in FIG Figure 4 is indicated. Between such layers with a parallel fiber course 19 to the longitudinal direction of extension A further layers can be provided, the fiber courses 20 and 21 of which are angled to the longitudinal direction A, for example at +/- 45 °, and cross each other.

Im Hinblick auf eine besonders steife Anbindung an das Board 2 kann sich der Kernabschnitt 11 mit den Torsionskästen 13 bis in den ersten Endabschnitt 7 der Hydrofoilfinne 3 hinein erstrecken, d.h. bei dem dargestellten Ausführungsbeispiel bis in den flanschartigen erweiterten Befestigungsabschnitt 9 hinein oder bis in einen im Board 2 formschlüssig aufgenommenen Abschnitt der Hydrofoilfinne 3.In view of a particularly rigid connection to the board 2, the core section 11 with the torsion boxes 13 can extend into the first end section 7 of the hydrofoil fin 3, i.e. in the exemplary embodiment shown, into the flange-like extended fastening section 9 or into a section of the hydrofoil fin 3 that is positively received in the board 2.

Die Aussteifung des Kernbereichs 11 erstreckt sich vorzugsweise über die gesamte Länge der Hydrofoilfinne 3 in Längserstreckungsrichtung A bis zu dem zweiten Endabschnitt 8, an welchem die Flügel 5 und 6 mittels des Verbindungsstabs 4 befestigt sind.The stiffening of the core region 11 preferably extends over the entire length of the hydrofoil fin 3 in the longitudinal direction A to the second End section 8 to which the wings 5 and 6 are fastened by means of the connecting rod 4.

Der Verbindungsstab 4 kann, sofern eine entsprechende Struktur nicht in die Hydrofoilfinne 3 aus Faserverbundwerkstoff integriert wird, aus Metall, vorzugsweise einer Stahl-, Titan- oder Aluminiumlegierung, gefertigt sein. Er weist einen Durchmesser im Bereich von etwa 10 bis 25 mm auf, wodurch der Strömungswiderstand im Wasser gering bleibt. Die Länge des Verbindungsstabs 4 liegt vorzugsweise im Bereich von 400 bis 900 mm. Im Hinblick auf eine einfache Fertigung und Montage kann der Verbindungsstab 4 mit einem konstanten Durchmesser ausgeführt sein. Es können jedoch auch lediglich Abschnitte, beispielsweise der Bereich, welcher in der Aufnahme 10 festgelegt ist, mit konstantem Querschnitt ausgeführt sein.If a corresponding structure is not integrated into the hydrofoil fin 3 made of fiber composite material, the connecting rod 4 can be made of metal, preferably a steel, titanium or aluminum alloy. It has a diameter in the range of approximately 10 to 25 mm, which means that the flow resistance in the water remains low. The length of the connecting rod 4 is preferably in the range from 400 to 900 mm. With a view to simple manufacture and assembly, the connecting rod 4 can be designed with a constant diameter. However, only sections, for example the region which is defined in the receptacle 10, can also be designed with a constant cross section.

Der vordere Flügel 5 und der hintere Flügel 6 sind in Fahrtrichtung hintereinander liegend angeordnet und jeweils lösbar an einem Ende des Verbindungsstabs 4 befestigt. Insbesondere sitzt der vordere Flügel 5 an einem vorderen Endabschnitt und der hintere Flügel 6 an einem hinteren Endabschnitt des Verbindungsstabs 4, so dass der vordere Flügel 5 in Fahrtrichtung vor der Hydrofoilfinne 3 und der hintere Flügel 6 in Fahrtrichtung hinter der Hydrofoilfinne 3 liegt.The front wing 5 and the rear wing 6 are arranged one behind the other in the direction of travel and each detachably attached to one end of the connecting rod 4. In particular, the front wing 5 sits at a front end section and the rear wing 6 at a rear end section of the connecting rod 4, so that the front wing 5 lies in front of the hydrofoil fin 3 in the direction of travel and the rear wing 6 lies behind the hydrofoil fin 3 in the direction of travel.

Sowohl die Befestigung des Verbindungsstabs 4 an der Hydrofoilfinne 3 als auch die Befestigung der Flügel 5 und 6 an dem Verbindungsstab 4 können lösbar ausgebildet sein. Hierdurch können Verbindungsstäbe 4 unterschiedlicher Länge an der Hydrofoilfinne 3 befestigt werden, um die Lage der Flügel 5 und 6 zu verändern. Ferner können unterschiedliche vordere und hintere Flügel 5 und 6 an dem Verbindungsstab 4 befestigt werden. Die Flügel 5 und 6 können aus Faserverbundkunststoff oder einem Schichtverbundwerkstoff hergestellt sein.Both the fastening of the connecting rod 4 to the hydrofoil fin 3 and the fastening of the wings 5 and 6 to the connecting rod 4 can be made detachable. As a result, connecting rods 4 of different lengths can be attached to the hydrofoil fin 3 in order to change the position of the wings 5 and 6. Furthermore, different front and rear wings 5 and 6 can be attached to the connecting rod 4. The wings 5 and 6 can be made of fiber composite plastic or a layered composite material.

Durch die vorstehend erläuterte Struktur der Hydrofoilfinne 3 wird eine sehr steife Abstützung von an derselben sowie an den Flügeln 5 und 6 angreifenden Biege- und Torsionskräften gegen das Board 2 erzielt. Dies wirkt sich vorteilhaft auf das Fahrverhalten beim Kitesurfen und Jetskifahren aus.Due to the structure of the hydrofoil fin 3 explained above, a very stiff support of the bending and the same as well as on the wings 5 and 6 is provided Torsional forces against the board 2 achieved. This has an advantageous effect on the driving behavior when kitesurfing and jet skiing.

Die Erfindung wurde vorstehend anhand eines Ausführungsbeispiels näher erläutert. Sie ist jedoch nicht hierauf beschränkt, sondern umfasst alle durch die Ansprüche definierten Ausgestaltungen. Insbesondere können technische Einzelmerkmale auch dann miteinander kombiniert werden, wenn dies nicht ausdrücklich beschrieben ist, solange eine solche Kombination technisch möglich ist.The invention was explained in more detail above using an exemplary embodiment. However, it is not limited to this, but encompasses all the configurations defined by the claims. In particular, individual technical features can also be combined with one another if this is not expressly described, as long as such a combination is technically possible.
