The Basic Principle Of Flight Essay

1005 words - 5 pages

Flight has been a dream of mankind, after the completion of the first powered airplane flight initiative from the Wright brothers, aviation technology is changing rapidly. From ancient light aircraft to a hundred tons airliner or even a fighter jet that flexible than eagle, flying technology has become one of the amazing achievement in science and technology.
Aerodynamics is a fundamental principle of flight and civil aircraft unit, in order to have the ability to move on the sky, the force balance of the air lift must be greater than weight and the thrust is greater than the drag. An airplane uses wings for lift and thrust engines. Drag is reduced by the smooth shape of an airplane and its ...view middle of the document...

)
Thrust
Thrust is a force that push plane to forward, to be able to to keep moving plane need more thrust than drag. Thrust itself is a force that can best be described by Newton's second law. The basic form of this law is: F = ma (Which states that force (F) is equal to mass (m) times acceleration (a). Acceleration is the rate of change of velocity over time. Thrust (T) is produced therefore by accelerating a mass of air.)

Then let’s discuss about the basic aircraft control objects (wings, tail, elevator, rudder and ailerons). Basically the center of gravity of aircraft is located near the wing. When the body of aircraft want to lift up, its depend to the elevator up to the horizontal stabilizer on the body. When the aircraft want to turn, the rudder and aileron is needed. But if just rely on one of the function (rudder or aileron), it still can turn however the reaction is slow and the turning is difficult to operate.
Elevator
It located at the horizontal of the aircraft tail, the body responsible for the elevation (pitch) angle.
Rudder
It located at the vertical of the aircraft tail, the body responsible for the yaw angles.
Aileron
The device is on the wing, it was responsible for the roll body tilt (Rotate).
Flaps
If the passenger is sitting near to the wing, they should see some small grow at the backend of the wings when taking off or landing, the main purpose of flaps is to increase the area to get a larger lift as well as will increase air resistance to slow down. Therefore, by using the flap can shorter the runway and takeoff distance.
Landing Gear
Commonly called as aircraft feet, landing gear during takeoff and landing. It must bear the entire weight of the body, and therefore it very important. Of course, there are certain speed limit for it, speeding landing or...

The Golden Age of Flight

1080 words - 5 pages The 1930’s is considered the Golden Age of Flight due to the rapid advances in technology regarding the introduction of flight in World War I and an increase of mass production ability. As the first commercial flights began during the beginning of the decade, approximately only 6,000 passengers boarded a plane. By 1934, there were about 450,000 and in 1938 there were bout 1.2 million passengers (Air Transport). Improvements in air travel

The Physics Of Flight Essay

807 words - 4 pages The Physics of Flight Flight is composed of four basic ideas thrust, drag, weight, and lift. Drag resists forward motion and thrust fights to overcome it. Weight pulls an object down to Earth and lift tries to keep it in the air. Those four basic ideas govern all aspects of flight.
