Spitfire Wing

This section will describe the process to build the spitfire wing as seen in the picture to the left corner of the screen. In this section we will not discuss the wheel well, cannon, tip light, aileron, Gun or wheel bubbles. Covering well be in a separate section. We will however talk about the support wing mount brackets.




Wing box build and assembly.

The wing is supported with a box main spar. The spare has a top, bottom, front and rear spare. You build the top or bottom, and use the front and rear spare to develop the total spar. To the right is the bottom spare.


Wing Center Main Box


To the left is the front spare with a separator box. This box is the key to the proper alignment of the rest of the wing. To the right of this alignment separator will house the wheel well. The right end of this box will also have the attachment bars. This area is very well built and rugged. Further pictures will detail the total wing.


Rib construction, rib caps and cut outs.

The wing has nine wing ribs. The ribs are made from 11mm plywood. They have a rectangular cut out which allows you to slide the rib in place and glue it with T88 epoxy. And box in the rib with 1/4 inch strip material. Each rib will have a slight angle starting with zero degree pitch to 2.3 degrees by the time you get to rib thirteen.





Attach wing to center section.

At this point we see gears, center wing and gas tank attached.



Leading, trailing and wing tip build.

After the all ribs have been assembled over the box, you place a series of tapered spruce strips on the leading and trailing edge. You next sand the edge which is now 6 strips of 1/8 inch X One inch spruce. The ribs are then capped with a 5/16 wide X 1/8 inch spar cap. The original design was not completed with this strip. The designer had not decided what to do do next. I decided that the wing if covered at this time would present a potato chip airfoil. I designed a leading edge epoxy glass structure about ten inches wide at the tip and about four inches at the tip. The structure at this time became very rugged and easy to handle




Bracket construction and attachment.

The wing at this stage was not ready to be kitted by the designer. So using the same technique he used in his P51 Mustang I proceeded to design the brackets and support plates. I'll add a complete page for this process at a later date.
