R
R The inboard flap is a fowler flap with a tab on its trailing edge. In its
R retracted position the inboard flap assembly is the wing trailing edge
R between the fuselage side and the outboard flap.
R
R The spars,the ribs and the skin of the inboard flap are made of aluminum.
R The nose of the tab is also made of aluminum. The trailing edge and the tab
R are made of honeycomb core with a skin made of aluminum sheet metal.
R
R The drive strut assembly-track 1 attaches the inboard flap assembly to the
R carriage assembly-track 1. Two bolt connections attach the drive strut
R assembly-track 1 to the drive trunnion. A forked bolt assembly attaches the
R drive strut assembly-track 1 to the rotary actuator-track 1.
R
R An eccentric spherical bearing attaches the drive trunnion to the carriage
R assembly-track 1. The drive trunnion is a fail-safe part.
R
R At RIB10 there are two brackets. The brackets attach the drive strut
R assembly-track 2. Bolts connect the drive strut assembly-track 2 to the
R brackets. The drive strut assembly-track 2 is a fail-safe part.
R A bracket at RIB9 attaches the carriage assembly-track 2 with an eccentric
R spherical bearing.
R
R Three hoisting fittings are installed to lift the inboard flap.
R At each end of the inboard flap assembly there are adjustable seal
R assemblies.
R
R The tab of the inboard flap is operated by a linkage system which is
R installed at RIB3 and the track 2 station. The linkage system at RIB3 is
R attached to the shroud box and the tab. Drive rods operate via bellcranks
R the tab. At track 2 station there is a drive rod linked to the carriage.
R The support system of the tab is installed at RIB6. It has brackets and rods
R which support the tab during the extension of the flap. Fairings at RIB3 and
R RIB6 cover the linkage and the support system.
R
R At the outboard end of the flap there is an interconnection strut . It
R connects the inboard and the outboard flaps. In case of a drive station
R failure, the interconnection strut carries the loads which result from such
R failure.
