PART
ONE: ~

*Air
Frame: the whole of an aircraft without its engines, it’s the body which
protects and holds all the aircraft components.

*Jet
Engines: it is used to suck high amounts of air and to compress the air and the
result is high power of thrust.

*Wings:
~ are long pieces of metal and its function is to equalize the plan during
flight, wings consists of: ~

-Spoiler:
its function is to reduce the speed and stop the plan while landing.

-Flap:
its function is to increase the lift or drag, and it’s used to reduce landing
speed.

-Ailerons:
its function is to allow the plan to roll left or right and bank during flight.

*Fin: ~
it is a long vertically wing and it consists of: ~

-Rudder:
its function is to move the nose of the plane left or right.

*Tail
Plane: ~ it is a short wing, its function is to produce lift and balance the
plane, and it consists of: ~

-Elevator:
its function is to move the nose of the plane up or down.

*Wheels:
are huge circles of tyre and its function is to support the whole weight of the
plane and to move the plane on the land during landing and takeoff.

PART
TWO: ~

i)                   
The component parts:~

-Wings consist of spoiler, flap, aileron, leading edge flap,
port navigation light, landing lights and fuel tanks.

-Fin consists of rudder.

-Tail plane consists of elevator.

ii)                  
Locate components:~

-Wings are located in the middle of the aircraft, ailerons
and flaps are located in the rear edge of each wing.

-Jet engines are located just under the first point of the
wing.

-Fin is located vertically at the end of the plane; rudder
is connected to it just behind it.

-Tail Plane is located horizontally at the end of the plane
and elevator is connected to it just behind it.

-Wheels: one is located just down in front of the plane and
the other two wheels are located under the wings.

iii)                
Connect components:~

Almost all of the wings fin and tail plane are connected
with long strong bolts and hinges, except part of the wings, fin and tail plane
are connected to the airframe by welding.

-wheels are connected by flywheel and flywheel is joined to
the landing gear shaft by bolts.

iv)                
Material:~

-Totally all of the aircraft components are made from high
light strong aluminium or mixture of titanium, except some other parts like the
wheels which are made from strong heat resistance rubber.

v)                 
Purpose:~

-The frame is made from light aluminium and the plane almost
looks like a bird, the purpose is to increase the speed of the plane during
flight, increase the lifting force and to reduce the drag force from the plane.

PART
THREE: ~

*What
is it called?

-It is
called aircraft known as Boeing 747.

*What
is it function?

-Its
function is to travel thro air and to takeoff and land during each flight.
