2015 SAE Aero East Design Team Initial Test Flight Vibrations induced by the motor did not excite natural frequencies of the motor mount Triple tail tested successfully Distance between tail and wing section tested successfully Secondary Test Flight Rudder control surface proved insufficient Telemetry unit collected flight data Adequate Take-off distance (< 200ft) Sustained flight in high wind conditions ( mph) Tertiary Test Flight 18 lbf payload lifted Results and Discussion 15

2015 SAE Aero East Design Team Results and Discussion 16 Take-Off Speed ≈ 16 mph Max. Speed ≈ 46 mph Max. Elevation ≈ 276 ft Predicted: lbf payload

2015 SAE Aero East Design Team 17 Project Budget Parts Cost – Budgeted Parts Cost = $ – Actual parts cost ≈ $1600 – Able to reuse some parts and materials from 2014 project Travel Cost – Available Travel Budget: $4500 – Projected Travel Costs: Renting vehicles: ≈ $900 Gas Estimate: ≈ $600 Hotel reservations: ≈ $1200 Meals & Incidentals: ≈ $1400 Total: ≈ $ 4100

2015 SAE Aero East Design Team Recent Work 18 New Payload Box: – Steel and Aero Ply Construction – Steel section to act as ballast Modified Verticals, Elevators, and Rudders – Increase in control surface area – Increased structural integrity – Counter-balanced rudder design
