Aircraft

In the past, there was no air transport, only land and offshore transportations were available, the is due the technology of design and material which engineers have got, and in one day air transports were available, but there was many major problems with the aircrafts, this is all because the design and material of the aircraft was made off, the first materials which were mainly used was wood and linen fabric. Then years passed, aircrafts started to be more safe and useful, aircraft industries used aluminum alloy, and more years passed industries started to use stainless steel and titanium, which was farther more safe and good

In the aircrafts components the first main part is the fuselage or the airframe which is mostly made now from titanium or fibers of glass, carbon graphite or boron, it’s the core of the aircraft, and the wing and tail are attached to it therefore it must be very strong. Most wings are made from stainless steel and mixture of titanium, the design of the wing is long and almost flat underneath, so the air can move faster under it and produce more pressure on it, so there is less pressure above the wing. The material and design of the plane is light and sharp, so it can fly easily and reduce the drag fore.

Overall as we can see that the most important of making the airplanes fly in a good performance it’s the design of it and the material used on it, without any of those, major problems can happen, so to avoid this things, engineers must use the right material and the correct design to give more lift, avoid all harmful rays and all other factors.

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 tire 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: ~

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.

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.

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.

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

Purpose: ~
-The frame is made from light aluminum 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.
