*.Focus Point: How are Aircraft Classified?Instructional Objectives: (SWBAT):1) Explain the 2 primary classes of aircraft.2) Discuss types of heavier than air aircraft.3) Identify 2 types of fixed wing aircraft. Lesson # 2 *
-
*I) What are the two primary classes of aircrafts: 1) Lighter-than air:
2) Heavier- than air:
-
*1) Lighter-than air: Hydrogen was used (flammable gas).
Uses gas to keep it aloft
Eventually slighter heavier helium (non flammable) was used
-
*II) Lighter-than air: 1) Non-rigid: free balloon or hot air balloon, has no internal or external framework. Has no steering mechanism.
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.
-
*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.
-
*2) Heavier-than air: All other types.
-
*III) Heavier-than air:1) Rotary wing: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.
-
*Powered by rotating blades.
blades may be tilted in any direction to control flight path. B) Helicopter:
-
*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
-
*
-
*C) Amphibians: can operate either on land or on water.
-
*.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?Lesson # 2*
