Thrust is the forward movement of the plane. … After this, paper airplanes are really gliders, converting altitude to forward motion. 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 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. When these four forces are used in balance, paper airplanes will fly longer.
The Dynamics of Flight
A thinner design works best for paper airplanes because it fundamentally creates less material to drag the plane, while thicker designs will create more resistant force to impede the plane’s flight. Lastly, the thrust is any force that propels the plane forward.
Expert Level: The Hammer. While there are far more advanced paper airplanes, this one, in my opinion, is the perfect balance of complexity and accessibility for the Average Paper Airplane Joe. It has far more folds than the previous two models, and also flies the best and farthest.
In the same way a rock that is thrown pushes its way through the air as compared to a cotton ball, a paper airplane with more mass flies faster and farther than a paper plane with less mass, up to a point. If the mass is too great, the wings can’t hold the plane in the air.
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.
The weight of the paper plane also affects its flight, as gravity pulls it down toward Earth. All of these forces (thrust, lift, drag and gravity) affect how well a given paper plane’s voyage goes.
The wide planes traveled an average distance of 30 feet 2 inches. The long narrow planes traveled an average of 21 feet and 3 inches. The wide planes traveled an average of 9 feet 1 inch farther than the long narrow planes. We determined that wide airplane designs fly farther than long narrow designs.
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.
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.
As the plane moves forward, its wings cut through the air to generate a small amount of lift. As the air rapidly flows over and under the paper wing, a tiny vacuum is formed over the top of the wing to hold the plane aloft. As the forward motion diminishes, the airflow over the paper wing slows and the lift is reduced.
Like all things that fly, there are 4 forces of flight that act on a paper airplane, thrust, weight , lift and drag.
The four forces are lift, thrust, drag, and weight. As a Frisbee flies through the air, lift holds it up.
How long can I stay up? Gliders can remain flying as long as there is lift available. Using thermals, this is about 8 hours. By using prevailing winds blowing up a slope, a glider can be flown for as long as the wind is blowing.
Among the most sensational is that the size of the flock has a significant impact on how fast the birds can fly. The larger the flock, the higher the speed. … The result is clear: bigger flocks travel faster, no matter what species they belong to.
Each wing was tested 20 times. It was concluded that Airfoil Three generated the most lift, with an average 72 grams of lift. Airfoil One generated the second most lift with an average of 35 grams.
There are four main load sources acting on an aeroplane – aerodynamic forces, inertia, ground reactions and thrust.
Planes do not actually defy gravity, though. Instead, the tilt and area of a plane’s wings manipulate the air particles around the plane, creating a strong enough lift that the force of gravity is overcome by the force of the air beneath the wings.
Weight and aerodynamics (airfoil) are the two important factors in determining the sink rate. The lighter the glider is, the better the sink rate. … Also, an airfoil with a larger lift coefficient translates into a better sink rate. Weight is the most important of these two factors.
