Thrust

• Twisted Airfoil

15
Thrust

• Twisted primaries in large birds
• Whole wing in small birds
• Momentum in large birds

16
Wing Shapes

• A bird that soars slowly on rising air
• A bird that glides in high speed sea-breezes
• A bird that uses flight to power from the ground
  to a safe perch
• A bird that flies for extended periods at high
  speeds
• A bird that flies through dense brush at
  slow/moderate speeds
• A bird that puts on bursts of speed to catch
  other birds through dense brush

17
Wing Shape Choices

• Long / Short
• Pointed / Rounded
• Slotted / Unslotted
• Wide / Narrow

• Soaring slowly
• Glides quickly
• Fast short flight
• Fast long flight
• Moderate speed through brush
• Fast short speed through brush
