WING Part II

Cochrane, Alberta, Canada

I have designed and fabricated my own design of slotted flaps for my aircraft.  The hinge material is 1/4 inch phenolic instead of aluminum for ease of installation and bonding onto existing adjoining surfaces.  As a result there will be a slight drag penalty but will be reduced by a fairing cover later.  My drive rib will be the root rib which has been reinforced to the spar to give good rigidity along the flap spar.  This drive metal linkage has a6 ply fiberglass nut plate strip attached to the inside of the root rib with structural adhesive.  The AN3 bolts will be able to be lock wired so no daily inspection will be required.  The drive rib metal linkage will connect to a torque tube which will be fabricated through  the aft area under the seat.  Bolt holes are enlarged as seen in photo and will be filled with flox to create a solid core area for strength at this location.  The leading edge of the slotted flaps will have a light sandable foam added with a curved edge that will allow smooth airflow over the flap as it is deployed.

The slotted flap hinges will have the metal washers replaced with smaller 1" nylon type.

 

Below the tie down is formed in the corner against spar and one rib.  I layed in a thin flox layer in the bottom to create a flat bed along the bottom, then layed down the bid as per the manual with the bottom layer being 16 bid thick.  I then bonded in a 1/4" 2x2 block of phenolic with a 1/4" nit plate riveted in place.  A VOR antenna is installed in the right wing and a Glide Slope antenna in the left.

 

Below is the drive rib installed for the aileron.  It has the metal fork installed which is hanging out the bottom skin 1".  The three bolts on the fork bracket have metal locknuts on them and a dab of S-adhesive as well for protection.  They are not accessible in the future.

 

Below are the two u-shaped carbon fiber pieces I fabricated which are the bolt bracket, for the aileron bell crank pivot points.  The first photo shows them in the fabrication blocks and then they are in place in the wing.  Temporary  foam support walls are shown in place, supporting the 4 bid carbon fiber walls which anchor down the bell crank pivot point to surrounding surfaces.  The drive tube connecting to the aileron can also bee seen in the photo.
