Embodiment Construction

[0021] figure 1 and 2 Shown are Ω-shaped stringers 10 secured (eg, glued) to the skin 20 to reinforce the skin.

[0022] stringer along with figure 2 The cut plane extends perpendicular to the general direction, figure 2 The Ω shape can be clearly seen in .

[0023] The stringer 10 thus has substantially planar parallel claws 11 , 12 glued to the skin 20 . These claws 11, 12 are located on each side of the central area of ​​the stringer 10, which is formed by a base 13 substantially parallel to the skin 20 but remote from the skin, and the base 13 is extended on both sides so as to be inclined relative to the skin 20 Extends up to the flanks 14 , 15 of the respective jaw 11 , 12 .

[0024] The stringer 10 is formed, for example, from a composite material component.

[0025] The flanks 14, 15 of the stringer 10 have diameters D here, for example at regular intervals. 1 Some rows of holes 16, 17 equal to 10mm (in figure 1 and 2 Only one drainage hole for each flank is...

Abstract

A structural element of an aircraft comprises a hollow part. An indicator (40) provides a visual indication (for example by moving) if ice forms in a given region of the hollow part.

Description

technical field [0001] The invention relates to an aircraft structural part having a hollow portion and an indicator of ice formation in the hollow portion. Background technique [0002] The outer surfaces of an aircraft (whether for example at the fuselage or at the wings, for example) are generally formed by relatively thin skins, which are therefore traditionally reinforced by structural elements such as frames and stringers. [0003] In order to properly perform their mechanical functions without excessively adding weight, these structural parts generally have a shape forming a hollow portion inside the structural part, such as commonly used Ω-shaped stringers. [0004] Such hollow parts may thus form very troublesome reservoirs for liquids, typically condensate and flowing water, especially for structural parts located at low points of the relevant part (eg fuselage). [0005] The presence of water appears to be problematic when the temperatures encountered result in a...
