(CFP)
John Harris -Updates and Schedule -Summary
-Questions
3CFP Criteria Review
- Secure wings to fuselage
- Quick set up and tear down
- Distributes stress efficiently
4Motivation for CFP
- Problem for both Sub-groups
- Most Complex Structural Part
- Created Urgency in Individual Tasks
- Fuselage Frame
- Carbon Fiber Testing
- Foam Molding
5Candidate Solutions

11Fuselage Update
- Frame
- 1 aluminum square tubing
- Ensure durability
- Ease of manufacturing
- Skin
- Other priorities
- Put off until final dimensions of frame were
known
12Landing Gear Update
- Decided on Design
