1. Aviation “The Power of Flight” Engineering Technology Mr. Austin Engineering Technology Mr. Austin

2. Objectives Understand the concepts and properties of flight Identify different characteristics of wing and body structure Enhance vocabulary using aviation terminology Understand the concepts and properties of flight Identify different characteristics of wing and body structure Enhance vocabulary using aviation terminology

3. Unit Thinking Skills T-2: Evaluate information and technology applications critically, competently, and creatively T-8: Practice responsible use of technology systems, information, and software T-2: Evaluate information and technology applications critically, competently, and creatively T-8: Practice responsible use of technology systems, information, and software

4. Types of Transportation Air transportation Systems (Lighter- Than-Air Craft) (Heavier-Than-Air Craft) Water Transportation systems Land transportation systems Air transportation Systems (Lighter- Than-Air Craft) (Heavier-Than-Air Craft) Water Transportation systems Land transportation systems

5. Aerodynamics The study of the motion of air and how it reacts to objects passing through it

6. Lighter-Than-Air Craft Held aloft by captive gases Helium and Hot Air Density 1.23kg/m 3 Most energy efficient

7. Lighter-Than-Air Craft Balloons 1700’s Lift—Hot Air Airships Dirigibles (steerable) Hydrogen/ Helium Hindenburg Hot Air: 600kg Airship: 2400kg (same size balloon) Balloons 1700’s Lift—Hot Air Airships Dirigibles (steerable) Hydrogen/ Helium Hindenburg Hot Air: 600kg Airship: 2400kg (same size balloon)

8. Heavier-Than-Air Craft Most abundant aircraft Takes more energy to keep them in the air Easier to control Gliders, Planes, helicopters

9. Gliders Fixed winged aircraft No power source Still used today Must use thrust of another aircraft Fixed winged aircraft No power source Still used today Must use thrust of another aircraft

10. Airplanes Works on the principles of lift, gravity, thrust, and drag Can be agricultural or personal Speed range 7 mph to Mach 6.7 Can have more than one wing (Biplane) Can seat hundreds of people

11. Forces on a plane Thrust Drag Gravity Lift Thrust Drag Gravity Lift

12. Control of Air Craft Yaw Pitch Roll

13. Helicopters More access to places Vertical take off and landing Can “hover” in the air Rotating wings (rotary blades) make it fly Tail (auxiliary) rotor keeps the vehicle from spinning with the blades

16. Air traffic Control Flight Paths (Airway) Jet Routes Commercial East—19,000ft West—34,000ft Lanes are 8 nautical miles wide Restricted Fly Zones Flight Paths (Airway) Jet Routes Commercial East—19,000ft West—34,000ft Lanes are 8 nautical miles wide Restricted Fly Zones

17. Review What are the two types of Air Craft? What are the 4 forces on a plane and where are they located? What are the three controls of a plane and what do they control? What does aerodynamic mean? What are the two types of Air Craft? What are the 4 forces on a plane and where are they located? What are the three controls of a plane and what do they control?
