1. Flight Performance, Stability and Control PDR Brian Barnett Rob Benner Ryan Srogi John Keune Alex Fleck

2. Objectives Class 1 sizing of horizontal and vertical tails and control surfaces. Dihedral and static margin determination. Take-off, climb, and turn performance.

3. Tail Sizing with Historical Data

4. Tail Area = 3.31 ft. 2 = 1.29 ft. 2

5. Control Surface Sizing Max deflection = 30 deg for all control surfaces

6. Other Control Parameters Dihedral = 2 deg. –Based on historical data of high wing aircraft Static Margin = 15% –Mark Peters recommendation –Can be as low as 10% –Adjustable by moving battery pack

7. Take-off Performance

8. Climb Performance

9. Turning Performance =.141 rad/sec.

10. Tasks Remaining X-Plots for horizontal and vertical tails Location of aerodynamic center and center of gravity Endurance mission
