Slide 3

I) What are the two primary classes of aircrafts:

1) Lighter-than air:

2) Heavier- than air:

Slide 4

1) Lighter-than air:

Hydrogen was used (flammable gas).

Uses gas to keep it aloft

Eventually slighter heavier helium (non flammable) was used

Slide 5

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.

Slide 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.

Slide 7

2) Heavier-than air:

All other types.

Slide 8

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.

Slide 9

Powered by rotating blades.

blades may be tilted in any direction to control flight path.

B) Helicopter:

Slide 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…
