MAIN WING CONSTRUCTION
INTRODUCTION
.....
The main wing is a sandwich composite structure with solid foam
core, two layers of UNI at 45 degrees to the trailing edge of the wing
for torsional stiffness and surface durability, and spanwise tapes of
UNI for bending strength. The T.E. of the wing is perpendicular to BLOO.
(i.e. the trailing edge of the wing has no sweep). The ailerons are on
the inboard section of the wing, and are actuated by an aluminum torque
tube. Shear loads are taken by a vertical shear web.
.....
The main wing is constructed in one piece from tip to tip for
strength, lightness, and ease of construction.
CUTTING THE SPAR CAPS
.....
Begin by cutting the UNI spar caps using the suggested layout on
this page. Letter each one of them with a felt tipped marker for
identification later, in addition to marking a centerline in the middle,
(where the cap will cross BLOO when installed on the main wing). The
technique for cutting the spar caps is described in the Composite
Materials Education Chapter and should be reviewed at this time. Be sure
to carefully roll up and store the spar caps after cutting to prevent
damage.
JIGGING THE MAIN WING
.....
Construction begins by jigging the main wing on the jig table.
Locate the main wing cores that you have previously hot-wired. It is not
necessary to use either the aileron slot foam cores, or the main wing
trailing edge cores, at this time.
.....
Find the main wing core female jigging templates (6).
.....
Now study the sketches. The main wing cores are jigged upside down
on the jigging table using the main wing core female jigging templates.
If your table is not at least 200 inches long, you will have to extend
it with a few 2x4's using bando, in order to locate the BLOO main wing
core female jigging templates. Note that the shear web is perpendicular
to BLOG, and that the main wing core female jigging templates have
leading and trailing edges that are tangent, respectively, with the
leading edges of the main wing cores, and the main wing shear web.
.....
Begin by drawing a straight line along your jigging table and
marking the locations (BL's) of the main wing core female jigging
templates. Next, temporarily set the main wing core female jigging
templates on the table so that their trailing edges are along that
straight line and their positions coincide with the appropriate BL
locations. A string stretched spanwise with a weight attached at either
end (see CANARD chapter) may be useful.
