  1. Gliders in Flight Stability for Straight and Level Flight

  2. Glider in Flight

  3. Gliders Are Long Distance Fliers

  4. Gaining Altitude • Glider do not have an engine • Use rising air to gain altitude

  5. Balsa Glider Flight • Straight and Level = Maximum Distance

  6. Three axis of movement

  7. Movement in Yaw

  8. Movement in Roll

  9. Movement in Pitch

  10. Static Stability

  11. Dynamic Stability

  12. Lateral Stability: Roll • High wing aircraft are naturally stabilizing

  13. Lateral Stability: Dihedral

  14. Why does dihedral work?

  15. Why does dihedral work? Uniform Lift Weight

  16. Why does dihedral work? Weight Component of Weight Causing a Sideslip

  17. Why does dihedral work? Rolling Moment Lower Lift Lower AOA Higher Lift Higher AOA Induced Relative Wind

  18. Lateral Stability: Types of Dihedral No Dihedral Straight Dihedral Tip Dihedral Polyhedral

  19. Movement in Yaw

  20. Directional Stability: Keel Effect

  21. Directional Stability: Weather Vaning

  22. Directional Stability Moment Arms

  23. Directional Stability

  24. Movement in Pitch

  25. Avoiding the Stalling

  26. Center of Lift Weight and Balance Balanced, but easy to shift… VERY nose heavy! VERY tail heavy! Weight at Center of Gravity

  27. Center of Gravity Range
