2 Top View

3 Front and Side Views

4 Ducted Fan PROS  More efficient than comparable propeller  Customer interest  Improved safety  Quieter  Enables hand launch/belly landing CONS  Cost  Motor constraint  Duct weight  Duct design  Accessibility

5 Wing Shape Quasi-elliptic planform for decreased induced drag Ease of analysis and manufacturablility Structural integrity Mid-span dihedral FrontBack

6 Control Surfaces Dual-boom mounted tail  Broad, elevated configuration  Removes tail from direct fanwash Flapperons  Reduces weight and mechanical complexity http://en.wikipedia.org/wiki/Image:Sea.vixen.flying.arp.jpg

7 Ground Interface Advantages  Hand launch  Inexpensive  Reduces weight  Increased versatility of sites  No drag from gear Potential Issues  Durability  Crash Issues Hand Launch/Belly Landing

8 Table of Physical Properties Assumptions Cl max 1.2-1.6 η fan 80% C d0 0.01-0.04 L/D6-14 V stall 30 [ft/sec] Calculations from Assumptions W/hp2.5-3 W/S1.2-1.4 Weight~4.5 [lbs] S3.2 [ft 2 ] P1.5 [hp]

9 Key Technical Requirements  High-speed flight  Economic loiter and cruise  45 degree climb angle  10 degree descent angle  No landing gear exposed in flight
