HOW TO DRAW AN AIRPLANE VIDEO COMING SOON!


 

How Planes Fly

Lets learn about the Aerodynamics-
(The study of how air moves around objects)

1. The airfoil shape creates a lift force that pushes up the wing.

2. Four forces act on a plane in flight: thrust, drag, lift and weight.

3. Control surfaces on the wings and tail plane move to change the forces acting on the plane.


Lift Force

When a plane is moving along, the shape of the wing means that the air flowing over the wing travels farther than the air under the wing. The faster moving air above the wing has a lower pressure than the slower-moving air below the wing. This creates the lift that pushes the aircraft up into the air.

Flight Forces

When a jet plane flies in a horizontal line, the lift force balances the weight of the plane pushing down.

When a plane takes off, all of the engines power is used to generate a huge lift force. The lift force is greater than the plane's weight. The plane rises into the air. When the plane lands, the pilot reduces the speed. the plane's weight is then greater than the lift force. The plane lowers itself into the ground.

Forces called thrust and drag also act on a plane in flight. Thrust is the forward force caused by air rubbing against the plane's surface.

WOULD YOU LIKE TO BE A PILOT?

It takes many years to become an airline pilot. Pilots study many subjects, including aviation, avionics, and navigation. They must pass many practical, theoretical, and medical tests.
Most airlines also require pilots to have a certificate that shows at least 1,500 hours of flying experience.

After they are hired by an airline, a new pilot will spend several weeks training to fly a certain kind of airplane. Flight simulators are used to practice dealing with every possible emergency situation. It usually takes several years of flying as a first officer before a pilot can become a captain.


PILOT was a word long before there were any airplanes! Centuries before the first person steered a plane, a pilot was a person who steered a ship.



Controlling Flight

 


 


Airplanes have different parts that make them fly. Like the ELEVATOR FLAPS that when are moved up and down they make the nose go up and down.

RUDDERS are on the tail wing and it makes the airplane turn left and right.

Propeller
Propellers act as moving wings, driving a plane forward. Its a blade that spins with others to drive craft on top of the water.

Wheels and Pontoons

When a plane lands it needs to use its wheels to safely land on the ground, otherwise it would be nearly impossible to land a plane if it had to skid to a stop.

Some planes are built with air-filled tanks, or PONTOONS on the bottom in order to land on water.

How Wings Work

Wing Shape

A wing is curved and streamlined. In the air, a wing divides airflow into two flows, one traveling under the wing and one going over the top. The one on top moves faster.

The two flows of air move differently. That difference helps me lift the wing.

The fast moving air on top pulls on the air above it and takes it downward. The faster air moves, the less air pressure there is. So the air pressure above a wing is lower than below the wing.

The air; the angle of the wing, and air pressure differences around the wing create lift.

The higher air pressure below pushes the wing up.


 

JET PLANES IN THE AIR

How do get engines work?

Jet engines suck air in, compress it, and heat it in a combustion chamber. The heated air is expanded n a turbine. The expanded air shoots out the back at a speed higher than the air around it. This pushes the airplane forward, creating thrust.

Modern airliners all use a kind of jet engine called turbofan. This engine sucks air in with a giant fan. Some of the air passes straight through, and some of it is heated in the combustion chambers.


HOW DO JET PLANES STAY IN THE AIR?

To understand how an airplane flies, it helps to think of air like water flowing around the airplane. Airplane wings are curved so that air flows more quickly over the top of the wing than underneath. This reduces pressure difference between the top and bottom of the wing creates lift. The force of lift helps make airplanes fly.

The two forces, thrust and lift, work against the force of gravity.

Flight Forces
When A Jet Plane flies in a horizontal line, the lift force balances the wieght of the plane pushing down. When a plane takes off, all of the engine's power is used to generate a huge lift force. The lift force is greater than the plane's weight. The plane rises into the air. When the plane lands, the pilot reduces the speed. The planes wieght is then greater than the lift force. The plane sinks to the ground. Forces called thrust isthe forward force created by the engines. Drag is the backward force caused by air rubbing against teh plane's surface.
