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.
Claims17
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.
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,
- wherein a pressure plate body has 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 plurality of aerodynamic profile elements, wherein the plurality of 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 the outlet gap between adjacent supporting projections of the plurality of supporting projections.
