1. Aerospace Dimensions Introduction To Flight Chapter 1

2. Airplane Components

3. Gods, Angels, Prisoners, And Balloons ► What are three reasons why the myth of Icarus is not true? ► The Montgolfier brother’s created a manned, hot- air balloon that flew for 25 minutes in 1783.

4. Daniel Bernoulli ► Theories laid the groundwork for the science of manned flight. ► He discovered the relationship between pressure and fluids in motion. “As the speed of a fluid increases, the pressure of that fluid decreases.” Faster moving air…low pressure Slower moving air…high pressure

5. Sir Isaac Newton ► He figured out how forces are related to matter. ► Laws of Motion: Law of Inertia: Objects in motion or at rest stay until acted upon by an outside force. 2 nd Law: A force acting on an object causes it to accelerate in that direction. F = ma Law of Action/Reaction: for every action, there is an equal and opposite reaction.

6. The Language of Wings

7. The Four Forces of Flight ► The Natural Forces: Drag & Weight (Gravity) ► The Artificial Forces: Thrust & Lift

8. 3 Axis of Flight Longitudinal axis controls roll (ailerons) Vertical axis controls yaw (rudder) Lateral axis controls pitch (elevator)

9. Creating More Lift… 1. Greater surface area the greater the lift. Ex: Big wings or multiple wings. 2. Greater upper- curvature, called camber the greater the lift. Ex: C-5 Galaxies and 747 jets. 3. Increasing speed produces more lift. Ex: F- 15 Eagle.

10. Stalls ► The engine does not stop in a stall!!! Rather the airflow over the top or camber of the wing is disrupted and lift is no longer possible at that angle of attack. Solution: Decrease your pitch (drop the nose of the airplane.)
