1) Explain the 2 primary classes of aircraft. 2) Discuss types of heavier than air aircraft.

3) Identify 2 types of fixed wing aircraft. 3:16:23 AM

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

2) Heavier- than air:

3:16:23 AM

1) Lighter-than air: 1.Hydrogen was used (flammable gas).

2.Uses gas to keep it aloft 3.Eventually slighter heavier helium (non flammable) was used

3:16:23 AM

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. 3:16:23 AM

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.

3:16:23 AM

2) Heavier-than air:

All other types.

3:16:23 AM

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. 3:16:23 AM

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

3:16:23 AM

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…

3:16:23 AM

3:16:23 AM

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