# What Make Paper Airplanes Fly?

## What Make Paper Airplanes Fly?

Lift comes when the air below the airplane wing is pushing up harder than the air above it is pushing down. It is this difference in pressure that enables the plane to fly. … The wings of a plane are curved so that the air moves more quickly over the top of the wing, resulting in an upward push, or lift, on the wing.

## What force makes a paper airplane fly?

thrust
When you throw a paper plane in the air, you are giving the plane a push to move forward. That push is a type of force called thrust. While the plane is flying forward, air moving over and under the wings is providing an upward lift force on the plane.

## What causes a airplane to fly?

Airplanes fly because they are able to generate a force called Lift which normally moves the airplane upward. Lift is generated by the forward motion of the airplane through the air. This motion is produced by the Thrust of the engine(s).

## What is the science behind paper airplanes?

The air around you is one thing that helps a paper airplane fly. … The aerodynamics of a paper airplane will determine the distance and ease at which it flies. The aerodynamics of the plane will need to have little drag and be light enough to defy gravity. Paper airplanes also use the forces of lift and thrust.

## How do paper airplanes fly physics?

Paper airplanes are subject to the same physics as any jet you see in the sky. The forces of thrust, lift, drag, and gravity all work together to send your homemade aircraft flying. To understand how these forces work to create flight, think about movement: something has to push that plane forward.

## Why can planes fly upside down?

Stunt planes that are meant to fly upside down have symmetrical wings. They don’t rely at all on wing shape for lift. To fly upside down, a stunt plane just tilts its wings in the right direction. The way a wing is tilted is the main thing that makes a plane fly, and not the wing’s shape.

## How do planes fly against gravity?

Lift (upward force) and thrust (forward push, provided by a propeller) get a plane into the air. Gravity and drag (air resistance, which is friction caused by air rubbing against the plane) try to pull the plane down and slow its speed. … Lift from the wings is used to overcome the force of gravity.

## Why do heavier paper airplanes fly farther?

A paper airplane with a larger mass in the body and smaller wings will fly faster than one with a smaller body mass and larger wings because its “wing load” is larger.

## What type of paper airplane flies the farthest?

Drag, lift, weight and thrust – this need to be in balance for the plane to fly (Scholastic 2014). From the results of testing design number 2 flew the furthest with both the plane launcher and people throwing it.

## How do you make a paper airplane fly longer?

Here are a few ideas to get you started:
1. #1: Increase Lift. As the plane travels, air moves quickly over the top of the wings. …
2. #2: Limit Drag. Air molecules push against the front of the plane as it travels, slowing it down. …
3. #3: Change The Thrust. …
4. #4: Try A New Material.

## How does the weight of a paper airplane affect it?

The larger the paper airplane the more it will weigh, the more it weighs the more lift will be needed to keep it flying. Eventually weight will become greater than lift and the paper airplane will descend to the ground. In addition the larger the paper airplane the larger its wings can be.

## How does the type of paper affect a paper airplanes flight?

The type of paper used can affect its weight and the amount of friction that exists. How the plane is designed can also vary tremendously. The design of the wings, body, nose and tail can all drastically change the way the plane flies.

## How do you make a dart paper airplane?

4. Fold in One Wing. …
5. Open the Wings and Flip Over Your Plane. …
6. Fold in the Wing That Has Not Yet Been Folded. …

## What makes the best paper airplane?

## Is it possible to fly a 747 upside down?

The answer is yes for a “little” bit! Unlike military fighters, commercial planes do not have the engine power for sustained inverted flight and rely on lift from the wings. … Commercial airliners are only tested and certified for upright flight.” However, one Boeing aircraft has flown upside down – twice!

## Can pilots see at night?

The short answer is no. If you’ve ever gazed out your window into the inky blackness during a nighttime flight, you’ve probably wondered how the pilots are able to see anything from the cockpit. So, in the traditional sense at least, once the sun sets, pilots fly blind. …

## Which animal can fly upside down?

Almost all bat species hang upside down. Their feet have evolved to be relaxed in a clenched position (difficult for a human to imagine). When they’re ready to fly, they let go and gain momentum from falling, since their little legs and wings can’t give them the kind of lift birds get.

## What force pulls an aircraft down?

Gravity
Gravity is the force pulling the plane down. When the gravity is stronger than the lift, the plane goes down.

## What force keeps a plane in the air?

Lift
Weight is the force caused by gravity. Lift is the force that holds an airplane in the air. The wings create most of the lift used by airplanes.

## What fuel is used in Aeroplane?

Aviation kerosene
Aviation kerosene, also known as QAV-1, is the fuel used by airplanes and helicopters equipped with turbine engines, such as pure jet, turboprops, or turbofans.

## What material is airplane body made of?

The skin of an aircraft is the outer surface which covers much of its wings and fuselage. The most commonly used materials are aluminum and aluminium alloys with other metals, including zinc, magnesium and copper.

## How are airplane wings made?

The wings start from just assembling the metallic frame of spars and ribs, followed by adding the flight systems and aerodynamic components, fuel tanks, engine holders, and finally, the wingtips. All of this happens on an assembly line, where parts are added and tested being shipped to aircraft assembly plants.

## What material is used in aircraft construction?

Aluminium and its alloys are still very popular raw materials for the manufacturing of commercial aircraft, due to their high strength at relatively low density. Currently, high-strength alloy 7075, which contains copper, magnesium and zinc, is the one used predominantly in the aircraft industry.

## How fast does a paper airplane go?

According to Blackburn, “For maximum height and for a good transition to gliding flight, the throw must be within 10 degrees of vertical” — which shows that a speed of at least 60 miles per hour (97 kilometres per hour) is the amount needed to throw the paper plane successfully.

## How does gravity affect a paper airplane?

Gravity helps create lift for paper airplanes. Gravity is the force that pulls objects toward the Earth. … When paper airplanes are thrown up, gravity pulls them down. This movement causes a difference of air pressure on the airplane wings, which then causes lift.

## How do paper airplanes reduce drag?

One of the keys to reducing drag on the paper plane is to have thin wings. This has to do with a paper plane’s Reynolds Number, which indicates the significance of the viscosity of the fluid (air) on flight.

## How do you make a paper airplane fly straight and far?

Paper airplane that flies far and straight Flying Technique:

Hold the Plane behind the centre of the plane’s gravity centre. Keep your left foot slightly forward and launch it in 30 – 40 degrees angle, throw it steadily with a medium force. If it fails, tweak the tail wing slightly up and try again.

## How do you make a paper airplane that flies like a bird?

Peregrine Falcon—High-speed Wings
1. Fold the paper in half.
2. Fold the top down 2”.
3. Fold the top again in order to double the thick edge.
4. Fold the top edge in half again.
5. Turn the paper over and fold the top corners to meet at the center line.
6. ​Turn the paper over again and fold the plane in half towards you.

## What is the world record for flight time with a paper airplane?

29.2 sec
The longest time flying a paper aircraft is 29.2 sec and was achieved by Takuo Toda (Japan), in Fukuyama City, Hiroshima, Japan, on 19 December 2010.

## How does wingspan affect the flight of a paper airplane?

“Yes, wingspan will affect flight, however there will be a point where the size of the wingspan will create too much weight and drag to be effective. For a glider, which a paper airplane is the more lift the glider has the longer it can fly. However, you must keep the weight and drag in check to avoid flight failure.”

## Do longer paper airplanes fly farther?

Yes, the more air that can get under the wings the longer the airplane will stay airborne increasing the chances it will fly farther.

## How do you make a Suzanne paper airplane?
