How do airplanes fly around in the air?

Answer 1

Small aircraft can be designed and constructed by amateurs as homebuilts. Other aviators with less knowledge make their aircraft using pre-manufactured kits, assembling the parts into a complete aircraft.

Most aircraft are constructed by companies with the objective of producing them in quantity for customers. The design and planning process, including safety tests, can last up to four years for small turboprops, and up to 12 years for aircraft with the capacity of the A380.

During this process, the objectives and design specifications of the aircraft are established. First the construction company uses drawings and equations, simulations, wind tunnel tests and experience to predict the behavior of the aircraft. Computers are used by companies to draw, plan and do initial simulations of the aircraft. Small models and mockups of all or certain parts of the aircraft are then tested in wind tunnels to verify the aerodynamics of the aircraft.

When the design has passed through these processes, the company constructs a limited number of these aircraft for testing on the ground. Representatives from an aviation governing agency often make a first flight. The flight tests continue until the aircraft has fulfilled all the requirements. Then, the governing public agency of aviation of the country authorizes the company to begin production of the aircraft.

In the United States, this agency is the Federal Aviation Administration (FAA), and in the European Union, Joint Aviation Authorities (JAA). In Canada, the public agency in charge and authorizing the mass production of aircraft is the Department of Transport.

In the case of the international sales of aircraft, a license from the public agency of aviation or transports of the country where the aircraft is also to be used is necessary. For example, aircraft from Airbus need to be certified by the FAA to be flown in the United States and vice versa, aircraft of Boeing need to be approved by the JAA to be flown in the European Union.

Recently, as quieter aircraft are becoming more and more needed due to the an increase in air traffic, particularly over urban areas, MIT has designed a delta-wing aircraft that is almost silent and appears to be a practical design for widespread use.

Answer 2

Airplanes use a propeller or turbine to displace air, which causes motion of the aircraft. As the aircraft speeds up, the wings (which are shaped at a curve for a reason) displace air, creating low pressure above the wing and high pressure below the wing. This causes the air to "push up" on the wing, lifting the plane.

Answer 3

The flight of airplanes is caused by the lift generated by the faster moving air over the wings.

Answer 4

SIMPLY PUT: THE ENGINES PULL THE AIRPLANE FORWARD CAUSING AIR MOVEMENT OVER AND UNDER THE WINGS. THE AIR MOVING UNDER THE WINGS IS GREATER THAN THE AIR ABOVE THE WINGS. THIS IS CALLED LIFT.
TO COME DOWN, THE AIR FLOW IS MODIFIED BY TAB AND SPOILERS TO CAUSE THE LIFT TO DECREASE.
THIS IS A SIMPLE EXPLINATION, NOT AN EXACT SCIENCE, BUT THE MAIN IDEAS ARE THERE.

Answer 5

The shape of the leading edge of the wings causes a slight vacum over the wing as air moves over it, essentially pulling up on the wing and providing lift. small movable parts of the wing disrupt or enhance that vacum to "steer" the plane.

Answer 6

the engines on the wings spin fast enough to create a pressure against the wind so it flys and then the little flaps on the wings elevate the presure

Answer 7

It's because if they didn't fly around in the air they'd be buses.

Answer 8

I heard that all pilots are airbenders.
