The science of flight: Paper airplanes

A paper plane is a model of an actual (or imaginary) airplane made of paper. It is somewhat similar to the traditional Japanese folding paper craft, so some people call it aerogami. Creating paper airplanes is very interesting. Sometimes they are just for entertainment or to compete with other paper airplanes. Studying paper airplanes can teach us a lot about how the actual plane will stay in the air. Let us know more, then learn how to make paper airplanes!

There is some evidence that the paper kite and glider were born in ancient China and Japan. In Europe, during the Renaissance, the inventors tried to create a paper model of a flight machine. Wright brothers were aircraft inventors, and they did this by testing a small paper model! The toy paper airplane spread in the second half of the Second World War. As all materials and supplies are distributed, children make or accept planes made of paper instead of metal, wood or plastic!

Like a real plane, there are four main forces called aerodynamics. And it allows paper airplanes to stay in the air. The first thing you throw an airplane forward is called thrust. Lift is the force acting on the wing that helps the plane go up. Large wings increase lift. Gravity is the power to pull an airplane. Appropriate materials can make a lighter aircraft that can last longer. Finally, the drag (caused by the tail) is the opposite of thrust, which slows down the airplane. There are other factors that affect the flight of the paper airplane. The type of paper used affects its weight and the friction that exists. Aircraft design methods are also very different. The wing, fuselage, nose, tail design can completely change the flying method of the aircraft. This is an interesting experiment. Try out some variations to see which design achieves the best flight.

Paper airplanes have plenty of attractive things. Do you know that the largest paper plane has about 60 feet wingspan so far? You think you can make more big things but still you can fly? The maximum time that paper airplanes stay in the air was 29.2 seconds. Please try some tests and record your time with your own paper airplane. How late is it going on? Researchers believed that ancient Chinese made some form of paper glider, but the first genuine paper airplane began in 1909.

The first step in making a paper airplane is to decide which model you want to make. From fighter aircraft to gliders, even standard passenger aircraft, you can find various instruction manuals of paper airplanes online. For a very basic version, you need a rectangular paper, scissors, colored pencil, or a sticker to stick the sticker. Most basic paper airplanes do not require cutting, only a few simple folds are needed. More sophisticated models require more work and extra folding. Start with some basic tutorials and then try out advanced tutorials. In the process, invent your own design and see how they are compared!

As you know, the plane is not disposable - it is reusable. They are expensive to manufacture, but they can fly thousands of times. You and I can afford to travel the air as it divides the cost of the aircraft into hundreds of passengers, not tens of thousands of people. A one-time airplane will be very wasteful, but the rocket is always designed this way. If you only need to refuel the rocket instead of replacing it, you can drastically reduce the cost per shot. Prior to SpaceX, the products released were very expensive. They spend an average of 200 million dollars. SpaceX uses a new rocket to spend $ 62 million, but the number of rockets in use is decreasing. With this cheap pace, the space is no longer limited to big government budgets. Companies now can afford to do things in space

Do you know that an airplane is more expensive than a rocket? The cost of Airbus A 380 is 400 million dollars and the cost of rocket is less than 100 million dollars. There are thousands of flights on each plane and the rocket can only afford to buy tickets because it flies and is thrown away only once. Or they were familiar until SpaceX learned how to land the rocket and fly again later. Planetary Resources is a startup attempting to collect rocket fuel from asteroids. That CEO, Lewicki is the most eloquent - imagine you do not have to carry these fuels with you - imagine running around the edge of the Earth's gravity, the first space service station in the solar system Please refuel the engine and supply it to the tank before the mission phase
