Embodiment Construction

[0020] The present invention is described below based on the drawings explained above.

[0021] pass figure 1 and 2 , first describe the sealing profile 1 conventionally used to connect the first element 2 and the second element 3, for example in the embodiment the first element 2 comprises an aerodynamic lining 2 equipped with openings 4, with which the sealing profile 1 consisting of the device 3 The second element 3 fits and seals in the opening.

[0022] Thus, the sealing profile is provided with a rectilinear portion, which is fixed on the aerodynamic lining 2 of the first element. The first section 1a terminates in a circular tubular section 1b protruding relative to the first element 2, the tubular section occupying part of the opening 4, as in figure 1 shown in .

[0023] For example, the device 3 may be a device, usually included in the aircraft, that ventilates the APU when the aircraft is stationary on the ground and the APU is activated. Thus, the ventilation ...

Abstract

The invention relates to a sealing profile made of deformable material with which first (2) and second (3) elements can be connected and sealed, and when assembled and sealed the first (2) and second (3) ) component is used to prevent the sealing profile from being extruded and deformed. For this purpose, the sealing profiles (6 and 7) are given the shape of a wedge, which protrudes beyond the first element (2), against which the second element (3) presses on its inclined surface in order to facilitate its deformation and the first ( 2) and the connection and sealing of the second (3) element. In this position the surface of the wedge protruding beyond the first element (2) presses against the second element (3). The invention is preferably intended for use in aerospace structures, in particular structures in which the first and second elements form part of an aerodynamic surface.

Description

technical field [0001] As stated in the title of this descriptive description, the present invention relates to a sealing profile for achieving fitting and sealing between two elements; and its purpose is to facilitate said fitting and sealing, all of which in a way that prevents any loss of impermeability. [0002] In general, the invention can be applied to any sector of industry where it is necessary to achieve an assembled and impermeable connection between two elements, and in particular it can be applied to the aeronautical industry in order to achieve the formation of aerodynamic The connection and sealing between the various elements of the lining components. Background technique [0003] In the field of aeronautical structural design, it is necessary to ensure the fit and seal between elements whose outer surfaces form aerodynamic surfaces. An example of such a coupling is that when the auxiliary power unit (APU, usually installed in the aircraft) is in operation ...
