  1. DO NOW LESSON # 1. Identify 3 major aerospace manufacturing companies. 2. Explain how a person such as your self can own part of an airline company.

  2. . Lesson # 2 4/1/2014 6:58 PM Instructional Objectives: (SWBAT): • Focus Point: How are Aircraft Classified? 1) Explain the 2 primary classes of aircraft. 2) Discuss types of heavier than air aircraft. 3) Identify 2 types of fixed wing aircraft.

  3. I) What are the two primary classes of aircrafts: 1) Lighter-than air: 2) Heavier- than air:

  4. 1) Lighter-than air: • Hydrogen was used (flammable gas). • Uses gas to keep it aloft • Eventually slighter heavier helium (non flammable) was used

  5. 1) Non-rigid: “free balloon” or “hot air balloon”, has no internal or external framework. Has no steering mechanism. II) Lighter-than air: 2) Rigid: blimp, gas is contained in a fabric covered wooden or metal frame work. A gondola (control car) is underneath which carries engines and personnel.

  6. Note: The Hindenburg was a German Zeppelin, after a successful passenger flight began across the Atlantic caught fire while landing in New jersey in May 1937, killing 36 people and injuring many.

  7. 2) Heavier-than air: All other types.

  8. 1) Rotary wing: III) Heavier-than air: • Lift is generated by moving blades overhead which act as “revolving wings” A) Autogiro: non powered air driven blades. Forward flight is accomplished by use of a conventional engine and propeller. Forward motion caused free wheeling rotating blade.

  9. B) Helicopter: • Powered by rotating blades. • blades may be tilted in any direction to control flight path.

  10. 2) Fixed wing: A) Seaplanes: (flying boats) uses floats or hulls in place of conventional landing gear to take off and land on water . B) Landplanes: classified by location of wing, landing gear type etc…

  11. C) Amphibians: can operate either on land or on water.

  12. . Lesson # 2 April 1, 2014 • Focus Point: How are Aircraft Classified? SUMMARY (ACCOUNTABLE TALK): 1) What are the 2 primary classes of aircraft? 2) What are the 2 types of heavier than air aircraft? 3) What are the 3 types of fixed wing aircraft?
