Fly to a whole new world!
What is it's purpose
An airplanes purpose is to give fast and safe travel for people and cargo. It can be also used for the Military. There are on an average 6,000 planes in the sky every day.
How and why was it invented?
It was invented for transportation and for the curiosity of flying. The Wright Brothers wanted to make a more controlled version of a hot-air balloon, and a hang-glider.
The brothers based their idea on the Chanute-Herring glider. They wanted to make something similar to this, but to be able to fly longer and be a useful part of transportation. On December 17, 1903 Wilbur and Orville's dream of a motor powered aircraft came true. Then, 66 years later, a man landed on the moon. Helicopters and other flying machines were created due to the Wright Brothers invention. Today, there are thousands of flights daily.
How Do Airplanes Work?
Aircraft are powered by four basic forces: Thrust, Drag, Lift, Weight. Thrust is the engine powering the aircraft forwards, while Drag pulls the plane back. Drag is anything blocking the air the air from moving smoothly across the aircraft. Lift is used by the wings pushing the air down and pushing the plane forwards. Weight counteracts this, weight pulls the plane down. For an airplane to fly it needs thrust and lift.
The airplane was a great invention
Airplanes today are an extremely useful form of transportation. It transports people and cargo across the world. Most people don't appreciate how much cargo aircraft carry. Most of your goods are delivered by aircraft, especially from other countries. But sometimes airplanes aren't used for good ways, for instance 9/11. After the tragedy airplane security has been raised, and made much safer. Today, airplanes are the safest form of travel and transportation, even safer than a car.
“The desire to fly is an idea handed down to us by our ancestors who, in their grueling travels across trackless lands in prehistoric times, looked enviously on the birds soaring freely through space, at full speed, above all obstacles, on the infinite highway of the air.”- Orville Wright
