Some wing parts
were finally in use today.
Team Green got a
headstart on the wing kit this session, and spent the day working on
the wing spars. This included preparing the attach angles, doublers,
and tie-downs; then attaching all those parts. The students got to
practice tapping the tie-downs in order to fit an eye screw. The
spars will serve as the main framework for the wings, providing the
most support for the forces and weight loads placed on them.
Aside from that
section, Teams Blue and Red both worked on the fuselage side skins.
The pieces required a lot of preparation: cutting, dimpling,
deburring, priming, countersinking; practically every technique was
used before actually riveting them upon the fuselage structure.
Team Purple was
split into two sub-groups: one worked to finish constructing the map
box and began work on the supporting pieces for the battery and oil
tank; the other group finished the upper firewall assembly and began
planning the fuel line system.
