Cookie: units are in slugs, lbf, inch, seconds

Currently the Drag Buildup is not functional

• to be fixed: fuselage geometry definition need to interface with drag buildup parameters
• LG drag?

I don’t have a good justification for the aft section to be 24 inches to start with. empennage being 60-70% of the wingspan is a good place for starters

Limitations of this program

Masses that are not (yet) accounted for

• servos, wire
• adhesives
• connection between empennage and fuselage

Improvements to be made on estimations:

• Wing— currently uses just foam
• Fuselage— Dean has it work in progress

Configuration

Wing

No quarter chord sweep for the main wing

only one section, constant taper

taper ratio fixed at $\lambda=0.4$

Landing Gear

Assumes NLG is placed at the start of the main fuselage
