Trailing edge of an aircraft aerodynamic surface

摘要

The invention discloses a trailing edge (2) of an aircraft aerodynamic surface, which comprises an upper skin (6) and a lower skin (7), being the upper and lower skins (6, 7) made of composite material. In the trailing edge (2) a lightweight part (1) is assembled at an end section (13) of the upper and lower skins (6, 7). The lightweight part (1) is covered by a metallic sheet (8), and has a “V”-shaped cross section with arms and peak, where the peak of the “V”-shaped cross section has a rounded shape and is located opposite the end section (13) of the upper and lower skins (6, 7).

主权项

1. Trailing edge of an aircraft aerodynamic surface, comprising:
an upper skin and a lower skin, said upper and lower skins each being made of composite material and together forming an end section of the upper and lower skins; and a lightweight part comprising a rigid structure having a plurality of inner holes configured to reduce weight of the lightweight part, the rigid structure being covered by a metallic sheet, wherein the lightweight part having a “V”-shaped cross section with arms and a peak, where the arms form a central hole configured to receive the end section of the upper and lower skins, and where the peak of the “V”-shaped cross section has a rounded shape and is located opposite the end section of the upper and lower skins, and wherein the upper skin, the lower skin and the lightweight part, providing a continuous aerodynamic profile to the trailing edge.
