                                     9/13/2012 6:11 PM

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

 3) Identify 2 types of fixed wing
 aircraft.

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




2) Heavier- than air:




6:11:36 PM
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


6:11:36 PM
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.




6:11:36 PM
   2) Heavier-than air:




All other types.




6:11:36 PM
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.

 6:11:36 PM
        B) Helicopter:

• Powered by rotating
  blades.

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




6:11:36 PM
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…



 6:11:36 PM
6:11:36 PM
       C) Amphibians: can operate either
       on land or on water.
