Abstract
A vehicle 1 has shell-like cladding elements 3 which are arranged on the vehicle structure 2. An Inspection flap 5 is provided, which can be moved from a closed position into an open position by an actuating mechanism 7 and when in the open position, permits temporary access to a hollow space H of the vehicle. The actuating mechanism 7 has at least one push-to-open fitting 8 which interacts with the inspection flap 5 in such a way that when a force RB is exerted on the inspection flap 5 in the direction of the hollow space H, the inspection flap 5 is transferred from the closed position into the open position in an ejection direction RA. The push-to-open fitting 8 has an ejection plunger 9 guided in a plunger housing 10, which is preloaded in the closed position and is locked in the plunger housing 10 by means of a locking mechanism 11. The locking mechanism 11 is formed in such a way that when a force is exerted counter to the ejection direction Ra the locking mechanism 11 is released and the ejection plunger 9 is pressed in the ejection direction RA, wherein the ejection plunger 9 is permanently arranged on an inner side of the inspection flap 5. The flap is made from a fibre and matrix composite material. The flap construction aims to reduce discontinuities within a vehicles aerodynamic surface.
Description
Vehicle and method for producing an inspection flap
The invention relates to a vehicle with shell-like cladding elements, in which at least one inspection flap is provided. The invention likewise relates to a method for producing such an inspection flap.
Fibre composite components which have been produced from a fibre composite material are suitable in particular for lightweight construction because of their weightspecific strength and rigidity. Fibre composite materials here have a fibre material and a matrix material, which can be present separately before the production of the fibre composite component or can be provided in the form of so-called pre-pregs. The matrix material as a rule wets the fibre material completely and thus, following the hardening of the matrix material, forms an integral unit with the fibre material. This achieves the situation where the load-bearing fibres of the fibre material are forced into their predefined direction, and thus the load-bearing properties are used in a component-specific manner.
It is precisely in air and space travel and in automobile construction that the fibre composite materials, for example unidirectional laminates, offer a high lightweight construction potential for structural components and cladding elements, which means that, in particular in vehicles, weight can be saved and thus the fuel consumption and the costs can be reduced. In particular in aircraft, the external flow surface of cladding elements plays a particularly great role since, with the aid of entirely aerodynamically smooth, i.e. gap-free and step-free, surfaces, laminar flow is made possible, which further reduces the resistance of the aircraft. In this way, the energy needed for the onward movement of the aircraft can be reduced, which likewise leads to fuel savings.
To increase the probability of a laminar boundary layer on the flow surface, the flow surface which is formed by the outer surface of the cladding elements should be to the greatest possible extent continuously curved and as a result aerodynamically smooth and, in particular, exhibit no discontinuities within the surface. Fixing elements such as bolts or rivets which are led through the flow surface would
- 2 promote a change of the laminar boundary layer into a turbulent boundary layer, and are thus not suitable to provide laminar flow surfaces.
In addition, inspection flaps or maintenance flaps which are provided within the cladding elements and which are intended to permit access to hollow spaces located behind must, for the purpose of a laminar boundary layer, end flush and flat with the adjacent cladding elements, in order thus to ensure a good transition into the flow surfaces.
One problem in inspection or maintenance flaps within the cladding elements and thus within the flow surface of vehicles consists in the fact that these inspection or maintenance flaps need an actuating mechanism with which the inspection or maintenance flap can be opened and closed manually. These actuating mechanisms which, for example, can be handles, must be designed to be sufficiently large in order to be able to ensure their handleability and accessibility into the interior, for example even with winter gloves. However, these handles work as imperfections of an aerodynamic surface and are thus not suitable to be used as a basis for a flow surface around which laminar flow can take place.
It is therefore an aim of the present invention to provide an improved vehicle in which, within the flow surface of the outer cladding elements around which laminar flow can take place, an inspection flap is introduced which does not have a disruptive effect on a laminar boundary layer in the region of the vehicle and in particular promotes the maintenance of a laminar boundary layer. It is likewise an aim of the present invention to provide an improved method with which such an inspection flap within a cladding element can be produced.
According to a first aspect of the invention, a vehicle is provided according to Claim 1.
According to Claim 1, a vehicle with shell-like cladding elements is claimed, the cladding elements being arranged on a vehicle structure of the vehicle. In at least one of the cladding elements, an inspection flap, also called a maintenance flap, is provided, which can be moved from a closed position into an open position by an
-3actuating mechanism and which, in the open position, permits temporary access to a hollow space of the vehicle located behind.
Such inspection or maintenance flaps within the cladding of vehicles are used in particular to provide temporary access to the technical elements of the vehicle located behind the cladding elements, in order to maintain the former and, in the event of a defect, to replace them if necessary. Precisely in aircraft, such inspection or maintenance flaps are intrinsically important for daily operation, since otherwise access to the technical elements of the aircraft, which are highly safety-critical, cannot be ensured.
According to the invention, provision is now made for the actuating mechanism to have at least one push-to-open fitting, which interacts with the inspection flap in such a way that when a force is exerted on the inspection flap in the direction of the hollow space, the inspection flap is transferred from the closed position into the open position in an ejection direction, wherein the push-to-open fitting has an ejection plunger guided in a plunger housing, which is preloaded in the closed position and is locked in the plunger housing by means of a locking mechanism, the locking mechanism being formed in such a way that when a force is exerted counter to the ejection direction, the locking mechanism is released and the ejection plunger is pressed in the ejection direction, wherein the ejection plunger is permanently arranged on an inner side of the inspection flap.
According to the invention, provision is thus made for the actuating mechanism for opening and closing the inspection flap to have a push-to-open fitting, in which an ejection plunger is preloaded and locked in the closed position, the locking mechanism being formed in such a way that, with a pressure counter to the opening direction, the locking mechanism is released and the ejection plunger forces the inspection flap in the direction of the open position. The ejection plunger is permanently arranged on the inspection flap and thus prevents the inspection flap in the closed state from being able to move readily from its closed position. This is necessary in particular for flow surfaces in faster vehicles, such as aircraft, for example.
-4According to the invention, it is thus possible for an inspection or maintenance flap to be provided within cladding elements of surfaces around which flow takes place, without actuating elements, such as handles or hollows, arranged on the outer surface being needed, wherein the inspection or maintenance flap nevertheless can be opened simply and quickly. Thus, surfaces with a laminar boundary layer property, within which one or more inspection or maintenance flaps are located, can thus also be implemented.
According to an advantageous embodiment, the inspection or maintenance flap is produced from a fibre composite material having fibre and matrix material, in order thus to take account of the principle of lightweight construction.
It is conceivable that the inspection flap is produced from multiple plies of fibre material, wherein the ejection plunger is permanently arranged in a metallized region of the fibre material plies. This permanent arrangement of the ejection plunger within the metallized region of the inspection flap can be carried out, for example, by means of welding or soldering. Here, it is particularly advantageous if the ejection plunger is formed from a material which in particular can be welded or soldered onto the metallized region of the inspection flap.
It is self-evident that the ejection plunger is permanently arranged on an inner side of the inspection flap, wherein the inner side is oriented in the direction of the hollow space, to which access is to be permitted temporarily through the open state of the inspection flap.
A vehicle in the sense of the present invention is a movable object such as an airborne vehicle, a road vehicle, a rail vehicle or a water vehicle. Airborne vehicles in the sense of the present invention are in particular aircraft such as commercial aircraft or passenger aircraft, or rotary aircraft such as helicopters.
In a further advantageous embodiment, the cladding elements are partly or wholly likewise produced from a fibre composite material having fibre and matrix material, which means that all of the cladding of the vehicle is produced from fibre composite
-5materials and thus account is taken optimally of the principle of lightweight construction.
In order to promote the most durable laminar boundary layer in operation, it is quite particularly advantageous if the inspection flap ends flat on the outside with the surrounding cladding elements in the closed position and no jumps in the surface exist at the transitions between the cladding elements and the inspection flap.
In a further advantageous embodiment, the plunger housing is arranged on the vehicle structure, which means that the inspection flap in the closed position is firmly fixed to the vehicle structure.
In a further advantageous embodiment, the locking mechanism is arranged in the plunger housing, so that the ejection plunger is kept preloaded in the plunger housing in the closed position. If a force counter to the ejection direction is then exerted on the ejection plunger, then the locking mechanism within the plunger housing is released and the preloading force forces the ejection plunger in the ejection direction, so that the inspection flap moves from the closed position into the open position.
In order to close the inspection flap again, i.e. to transfer the inspection flap from an open position into the closed position, the inspection flap is pressed in the direction of the vehicle or hollow space of the vehicle, the ejection plunger being pressed counter to the preloading force in the plunger housing until the ejection plunger acts on the locking mechanism and thus locks the ejection plunger in the closed position.
Preloading the ejection plunger in the closed position in the direction of the open position can, for example, be effected by means of a spring, which is located in or on the plunger housing.
Here, it is conceivable that the ejection plunger guided linearly in the plunger housing is guided in the plunger housing in such a way that the ejection plunger remains in the plunger housing in the open position and there rests on an end stop. This prevents the inspection flap being able to be removed completely. However, it is also conceivable that the ejection plunger can be removed completely from the plunger
-6housing, which means that unimpeded access to the hollow space located behind is made possible. When the inspection flap is inserted, the ejection plunger must then be introduced into the plunger housing again and pressed in the direction of the hollow space.
In a further advantageous embodiment, the shell-like cladding elements together with the inspection flap in the closed position form on the outside a flow surface around which laminar flow can take place.
A second aspect of the invention provides a method for producing an inspection flap according to Claim 10. Accordingly, first of all a fibre composite material having a fibre material and a matrix material is provided, and also an ejection plunger of a push-to-open fitting of an actuating mechanism, as described above.
Then, in a region in which the ejection plunger is to be arranged, the fibre material is metallized with a metallic material, in order to cancel out the anisotropic material property of the fibre material there locally in the metallized region and to provide an isotropic region within the fibre material. Before or after the hardening of the matrix material infused into the fibre material, the ejection plunger is then soldered or welded onto an inner side of the inspection flap in the metallized region of the fibre material, which means that, following the hardening of the matrix material, the ejection plunger enters into an integral and therefore permanent connection with the fibre material.
Here, it is conceivable that the inspection flap is built up from multiple fibre material plies, wherein a plurality of the fibre material plies are metallized in a common region.
- 7 The invention will be explained by way of example by using the appended figures, in which:
Figure 1 - shows a schematic illustration of part of a vehicle with an inspection flap in the closed state;
Figure 2 - shows a schematic illustration of the inspection flap in the open state; and
Figure 3 - shows a schematic illustration of an inspection flap in the production process.
Figure 1 shows a detail of an outer structure of a vehicle 1, which has a vehicle structure 2 and external cladding elements 3. The cladding elements 3 form on their outer layer a flow surface 4 which, in particular, is intended to form a laminar boundary layer and on which a fluid is guided along at all times during the movement of the vehicle.
Within one of these cladding elements 3 there is an inspection flap 5 which, in the exemplary embodiment of Figure 1, is illustrated in a closed position. Here, the closed position means that the outer flow surface 6 of the inspection flap 5 ends flat at its transition points to the cladding elements 3 and their flow surface 4 there, and thus promotes the maintenance of the laminar boundary layer on the flow surfaces 4 and 6.
Arranged between the vehicle structure 2 and the inspection flap 5 is an actuating mechanism 7 which, in the exemplary embodiment of Figure 2, has at least two push-to-open fittings 8. The actuating mechanism 7 with the push-to-open fittings 8 is formed such that, in the closed position, an actuating force applied to the inspection flap 5 on the outer flow surface 6 in an actuating direction Rb leads to the inspection flap 5 being pressed in an ejection direction RAand thus being transferred from the closed position into the open position.
For this purpose, the push-to-open fitting has an ejection plunger 9, which is guided linearly in a plunger housing 10 and, in the closed position, is held by a locking mechanism 11 and preloaded with the aid of a spring 12. If, then, by actuating the
-8inspection flap 5 in the actuating direction Rb the locking mechanism 11 is released, then the preloading spring 12 presses the ejection plunger 9 in the ejection direction Ra, which means that the inspection flap 5 is shifted in the ejection direction Ra and thus transferred into the open position.
The open position is shown in Figure 2, wherein here the ejection plunger 9 has been guided wholly out of the plunger housing 10. This permits unimpeded access to the hollow space H located behind the cladding elements 3.
According to the invention, the ejection plunger 9 is arranged directly on the inner side of the inspection flap 5 and is permanently connected to the latter, so that in the closed position the inspection flap 5 is held securely by the plunger housing 10 arranged on the vehicle structure 2. If, then, the inspection flap 5 is inserted again, then the ejection plungers 9 are inserted into the respective plunger housing 10 and pressed in the actuating direction Rb, counter to the force of the preloading spring 12, until the locking mechanism 11 engages in the plunger housing 10 and keeps the respective ejection plunger 9 in the closed position in the plunger housing, counter to the preloading force of the preloading spring 12.
Figure 3 shows, schematically, part of an inspection flap 5 which is built up from multiple layers in fibre plies. In a metallized region 13, the fibre plies of the fibre material of the inspection flap 5 have been metallized by a metallic material, which means that in this region the anisotropic material property of the fibre material has been cancelled out and has accordingly been made isotropic. In this metallized region 13, the ejection plunger can then be soldered on or welded on, i.e. connected integrally to the metallized region, which means that the ejection plunger 9 forms a firm hold with the inspection flap 5.
Impregnation of such a hybrid fibre-metal semifinished product with a liquid matrix material and the subsequent hardening permits the implementation of integrally fabricated load introduction points which, in conjunction with a suitable mating piece, permit the use of a handle-less opening system for inspection flaps of fibre composite synthetic material design with a defect-free surface on one side. Because of the uninterrupted surface facing away from the ejection plunger 9, such an element can
-9be integrated in plate-like or slightly curved plastic laminates, which can be used as a covering plate or inspection flap on surfaces around which flow takes place.
