Joining arrangement for the lateral boxes of a horizontal tail stabiliser with a tubular central box and manufacturing method for said box
First Claim
1. Joining arrangement for two lateral boxes (11, 11′
- ) of a horizontal tail stabiliser of an aircraft, comprising upper skins (15, 15′
), lower skins (17, 17′
), using an intermediate joining part (31) both said part (31) and said lateral boxes (11, 11′
) being made of composite material, characterized in that said intermediate part (31) comprises a hollow central box (33, 63, 73) positioned laterally between the lateral boxes and including upper (35, 35′
) and lower (37, 37′
) lateral flaps to which said skins (15, 15;
17, 17′
) of the lateral boxes (11, 11′
) are joined using rivets such that upper (35, 35′
) and lower (37, 37′
) lateral flaps overlap said skins (15, 15;
17, 17′
), fitting plates (A) for a trimming device and fitting plates (B) for a pivoting device.

Abstract
Joining arrangement for the lateral boxes (11, 11′) of a horizontal tail stabilizer with a central tubular box and manufacturing method for said box. The boxes (11, 11′) are joined using an intermediate joining part (31) that comprises a central box (33, 63, 73), upper (35, 35′) and lower (37, 37′) lateral flaps, fitting plates (A) for the trimming device and fitting plates (B) for the pivoting device, the join being made with rivets between the skins (15, 15′; 17, 17′) of the lateral boxes (11, 11′) and said flaps (35; 35′; 37; 37′). The method for manufacturing the intermediate joining part (31) comprises steps to: a) Provide preforms suitable for forming said part (31); b) Form and cure the part (31) made from said preforms using an RTM method.
