Understanding Flight Dynamics: Weight, Lift, and Thrust Analysis

This presentation explores the fundamental principles of flight dynamics, specifically focusing on the A-10 Thunderbolt and SR-71 Blackbird aircraft. We'll examine critical forces such as weight, lift, drag, and thrust, illustrating these concepts through equations and practical examples. The analysis will also cover the effects of airflow on objects, using simple experiments with paper sheets and ping pong balls to demonstrate Bernoulli's principle and the balance of forces in flight. Join us as we uncover the science behind how aircraft achieve lift and maneuver through the skies.

  7. A-10 Thunder Bolt Weight Mass(m) = 13800 kg

  8. A-10 Thunder Bolt Weight Mass(m) = 13800 kg W = ?

  9. A-10 Thunder Bolt Weight W = m ∙ g Mass(m) = 13800 kg

  10. A-10 Thunder Bolt Weight W = m ∙ g = (13,800 kg) ∙ (9.81 m/s2)

  11. A-10 Thunder Bolt Weight W = m ∙ g = 135,378 kg ∙ m/s2

  12. A-10 Thunder Bolt Weight W = 135,378 N

  13. A-10 Thunder Bolt Level Flight L = ? W = 135,378 N

  14. A-10 Thunder Bolt Level Flight L = W W = 135,378 N

  15. A-10 Thunder Bolt Level Flight L = W = 135,378 N W = 135,378 N

  16. A-10 Thunder Bolt Level Flight (L = W) L = 135,378 N W = 135,378 N

  17. SR-71 Blackbird Steady Flight D = ? T = 290, 000 N

  18. SR-71 Blackbird Steady Flight D = T T = 290, 000 N

  19. SR-71 Blackbird Steady Flight (T = D) D = 290,000 N T = 290, 000 N
