WINGS - GENERAL - DESCRIPTION AND OPERATION
___________________________________________
1. General
_______
(Ref. Fig. 001)
The aircraft wing is a continuous structure which goes through the fuselage between Frames 36 and 42. It is made in three parts:
-
the center wing (zone 140)
-
the left outer wing (zone 500)
-
the right outer wing (zone 600).
The center wing is part of the fuselage and gives attachment points for the
outer wings. Each outer wing has a wingbox, leading and trailing edges and a
wing tip. The leading edge has attachments for the slats and the trailing
edge has attachments for the main landing gear, aileron, flaps and spoilers.
A wingtip fence is installed on the wingtip.

3. Description
___________
A. Center Wing
R The center wing is installed in the center fuselage between Frames 36 and R 42 and includes:
-
the front and rear spars (at Frames 36 and 42)
-
the upper and lower skin-panels
-the two main frames (Frames 36 and 42) R - a set of 38 aluminium alloy rods (four assemblies of six rods and two R assemblies of seven rods)
-the left RIB1 and the right RIB1.
The center wing has attachments for the left and the right outer wings at the left RIB1 and the right RIB1. The center wing-box has an integral fuel tank. Access to this fuel tank is through the access doors in Frame
42.
B. Outer Wing
Each outer wing includes:
-
the wing box
-
the wing tip
-
the leading edge and the leading edge devices
-
the trailing edge and the trailing edge devices.
(1) Wing Box
The main structure of each outer wing is the wing box which tapers from the wing root to the wing tip. Its front and rear spars extend from RIB1 to RIB27. The rear spar is made in three parts and has joints at RIB6 and RIB22.
The wing box has 27 ribs. The ribs are continuous between the front and the rear spars. The top surface of the wing box has two skin panels, and the bottom surface has three panels. Each of the wing panels extends forward of the front spar and aft of the rear spar. The leading and the trailing edge structures attach to these projections and to the front and rear spars. Stringers give strength to the top and the bottom skin panels.
The wing box makes an integral fuel tank and a vent surge tank. 21 access panels in the lower skin give access to the fuel tank and the vent surge tank. The wing box also has attachments for:
-
the leading edge and the leading edge devices
