Abstract

In order to allow or improve a laminar air flow in a transition region between aerodynamic profile elements, a pressure plate arrangement is proposed. The pressure plate arrangement comprises a pressure plate body and at least one cover strip, in particular a sealing strip. The pressure plate body has an outlet region from which free-flowing sealant can exit during pressing. The cover strip already contains cured sealant and presses the free-flowing sealant flat in order to be able to form the transition region.

First claim

The invention claimed is:

1. A production arrangement for producing a laminar flow surface between a plurality of profile elements, the production arrangement further comprising:
a plurality of aerodynamic profile elements forming a joint portion therebetween, the plurality of aerodynamic profile elements comprising a first aerodynamic profile element and a second aerodynamic profile element wherein a transition region is located between the first and second aerodynamic profile elements and configured to allow a laminar fluid flow flowing from the first aerodynamic profile element via the transition region to the second aerodynamic profile element,
a free-flowing or pasty sealant arranged on the joint portion, and
a pressure plate arrangement configured for pressing the free-flowing or pasty sealant within the joint portion, the pressure plate arrangement comprising a pressure plate body and at least one cover strip between pressure plate body and the free-flowing or pasty sealant, the pressure plate body having an outlet region which is configured to allow the free-flowing or pasty sealant to exit during pressing thereof and a plurality of supporting projections located on a common side of the transition region, the plurality of supporting projections support the pressure plate body against one of the first or second aerodynamic profile elements, wherein the supporting projections are arranged spaced apart from one another in a longitudinal direction of the pressure plate body extending parallel to a length of the transition region and delimit outlet gaps of the outlet region between the adjacent supporting projections of the plurality of supporting projections.

2. The production arrangement according to claim 1 , wherein the outlet region is arranged on a longitudinal edge region of the pressure plate body extending parallel to the longitudinal direction of the pressure plate body.

3. The production arrangement according to claim 2 , wherein a second outlet region is arranged on a second longitudinal edge region of the pressure plate body extending parallel to the longitudinal direction of the pressure plate body and spaced apart from the longitudinal edge region in a transverse direction of the pressure plate body.

4. The production arrangement according to claim 1 , wherein the pressure plate body, has at least one of
a pressure surface for pressing free-flowing or pasty sealant; or
a non-stick region comprising a pressure surface, with non-stick properties in relation to the sealant.

5. The production arrangement according to claim 4 , wherein the at least one cover strip is releasably fastened to the pressure plate body.

6. The production arrangement according to claim 5 , wherein the at least one cover strip is releasably fastened to the pressure surface.

7. The production arrangement according to claim 1 , wherein the pressure plate body has a plurality of positioning projections for positioning the pressure plate body relative to a further element, wherein the positioning projections are arranged spaced apart from one another in the longitudinal direction of the pressure plate body.

8. The production arrangement according to claim 7 , wherein, the positioning projections are arranged with a larger spacing than a spacing of the supporting projections.

9. The production arrangement according to claim 8 , wherein, the positioning projections are arranged at an integral multiple of the spacing of the supporting projections, and delimit outlet gaps of the outlet region between them.

10. The production arrangement according to claim 1 , wherein a further cover strip is provided which is spaced apart from the at least one cover strip in a longitudinal direction and delimits a filling gap with the at least one cover strip.

11. The production arrangement according to claim 10 , wherein a plurality of aligning elements which can be releasably fastened to the profile elements and which are configured to interact with the pressure plate arrangement such that the pressure plate arrangement is positionable along a joint portion formed by the profile elements so as to follow the joint portion.

12. The production arrangement according to claim 1 ,
wherein the pressure plate body comprises a longitudinal edge region from which the supporting projections project,
wherein, as seen in plan view, the pressure plate body, together with the supporting projections, delimits the outlet gaps only on three sides,
wherein, as seen in plan view, the fourth side of the outlet gap is delimited by a further element.

13. The production arrangement according to claim 1 , wherein a crosslinking device which is configured for at least one of partially crosslinking or curing free-flowing or pasty sealant and which is arranged on the pressure plate body, wherein the crosslinking device has a heating device for heating free-flowing or pasty sealant in order to partially crosslink or cure the free-flowing or pasty sealant.

14. The production arrangement according to claim 1 , wherein a crosslinking device which is configured for at least one of partially crosslinking or curing free-flowing or pasty sealant and which is arranged on the pressure plate body, wherein the crosslinking device has an irradiating device for irradiating free-flowing or pasty sealant in order to partially crosslink or cure the free-flowing or pasty sealant.

15. The production arrangement according to claim 1 , wherein the first and second profile elements and each of the plurality of supporting projections are located along a lengthwise edge of the pressure plate body.

16. A method for producing the at least one cover strip for use in the production arrangement according to claim 1 , comprising the following steps:
a) applying free-flowing and/or pasty sealant, which is also used in one of the devices, to a base plate;
b) pressing the free-flowing or pasty sealant to a defined thickness by means of a further plate to obtain a plate-shaped free-flowing or pasty sealant;
c) partially crosslinking or curing the plate-shaped free-flowing or pasty sealant to form a plate-shaped partially crosslinked or cured sealant; and
d) cutting the plate-shaped partially crosslinked or cured sealant to obtain the at least one cover strip.

17. A production method for producing a transition region between a plurality of aerodynamic profile elements, wherein the transition region is configured to allow a laminar fluid flow flowing from a first of the aerodynamic profile elements via the transition region to a second of the aerodynamic profile elements, comprising the following steps:
a) arranging the aerodynamic profile elements such that the aerodynamic profile elements define a joint portion;
b) applying free-flowing or pasty sealant to the joint portion, and, to form the transition region, pressing the free-flowing or pasty sealant by means of a pressure plate arrangement delimiting an outlet gap for free-flowing or pasty sealant, wherein a quantity of the free-flowing or pasty sealant is dimensioned such that, during pressing, some of the free-flowing sealant exits from the outlet gap as excess sealant;
c) partially crosslinking or curing the free-flowing and/or pasty sealant; and
d) removing the excess sealant,
