Balsa Wood Framed Aircraft Research & Rough Draft Development
Main Wing Technical Design
Goal: Use your Balsa Wood Framed Aircraft Rough Draft Development as a guide to create a technical drawing of your main wing part(s).
- Thinking about your Main Wing Design, decide how many panels will make up your main wing. Any place where there is a change in angle or look, a new panel is established. This should be reflected in your top sketch perspective.
- Draw your front main wing view FIRST. This drawing is to be at real life scale, or 1:1 scale. Remember, that means you are drawing the actual size of what your creation is going to be. This drawing will also cause you to think about the panels you need to construct.
- Now use your Top View Main Wing area to draw out your main wing panels. Plan you use of this space wisely, depending on the number of panels you need. Again, these drawings need to be at 1:1 scale. You will use these drawings as your patterns for construction!
- When finished, take a moment now to really darken and thicken your technical drawing lines. Keep dimension information lighter.
- Wrap your technical drawing with wax paper as demonstrated in class.
