Wing & Tail Structural Design Wing Structure to be Lightened Single Vertical Tail Redesigned Spars in Horizontal Tail Wing & Tail Structural Design

Wing & Tail Structure TEST PLAN Single spaced test wing will have ribs spaced at 2 inch intervals as designed. Double spaced test wing will have ribs spaced at 4 inch intervals. Tests on each wing: Deflection testing without skin Deflection testing with skin Torsion testing with skin Wing & Tail Structure TEST PLAN

Fuselage Design Warren Truss Tail Boom v. Pratt Truss Increased Cross Sectional Area Accommodate Passengers and Luggage Test New Design to Failure Compare with MAE434W Design Semi-Monocoque Fuselage Fuselage Design

Landing Gear design Thorough Analysis Completed Spring 2016 Simple Axle Design Chosen Design Modified with Springs and Dampers for Larger Aircraft Landing Gear design

MOTOR & Propeller Specification Motor Selection Validated in Spring 2016 Analyzed using eCalc Fall 2016 will Analyze Multiple Propellers Analysis will use eCalc and Crotor Propellers will Undergo Wind Tunnel Testing to Validate Analysis Goal is to increase Efficiency and Thrust MOTOR & Propeller Specification
