How does an airplane stay in the air? The answer lies in its design. Airplanes are built using lightweight materials such as aluminum and carbon fiber.
They also feature aerodynamic shapes that allow them to fly at high speeds without breaking apart, as well as finely-engineered engines and other mechanisms that allow them to take off.
Every part of an airplane, from its materials to its functions, is designed to achieve and maintain flight.
Airplanes are designed to withstand extreme conditions. For example, they are able to fly through storms and turbulence because their wings are strong enough to handle the pressure.
But just how do they do it? In this article, we’ll take a look at how exactly airplanes are able to stay in the air.
We’ll cover the history of airplanes, from the first flight to modern jets that can travel hundreds of miles per hour, looking at the science and engineering behind how airplanes can stay in the air. So let’s get started!
The History Of Flight
In order for us to understand how planes work, we need to start with where they came from.
Humans have dreamt of flying since the beginning of time, but until recently (only within the last 100 or so years) human flight was seen as impossible.
Mathematicians, engineers, and inventors spent hundreds of years coming up with their own designs for flying machines; Leonardo da Vinci, Samuel Langley, and George Cayley were among the famous scientists who tried their hand at creating a flying aircraft.
While gliders and flame-powered balloons had already allowed humans to travel through the air, there were still no sustainable and efficient ways for a person to achieve proper flight.
It wasn’t until the early 1900s when the brothers Orville and Wilbur Wright developed the Wright Flyer, which is generally accepted to be the first powered airplane capable of sustaining flight.
The Wright Brothers were able to achieve a flight of more than 850 feet, sustained over 1 minute in the air. From there, the world of aviation really took off.
The Wright Flyer is a ways away from the types of airplanes that we have now, and the designs of airplanes developed quickly over the following century.
Biplanes, which offered increased maneuverability as the sacrifice of a monoplane’s speed, helped to improve the stability of flight, while the inclusion of more-powerful engines meant that planes could fly faster and for longer.
World War I was the first war that utilized aircraft in combat; by the time World War II started, planes had massively improved.
Wooden frames were reinforced with metal for extra protection, increased engine power and maneuverability made flights longer, faster, and better suited for combat, and the planes themselves were designed to hold the added weight of guns (see also “Do Pilots Carry Guns?“), cargo, and multiple passengers.
Aircraft continued to develop following on from the end of World War II, with better designs and more advanced technology allowing for types of flight that early aviation pioneers could have never even dreamed of.
Commercial flights became increasingly popular, with larger bomber aircraft being converted to planes that could hold several passengers.
1947 saw the first time that a plane broke the sound barrier; in 1988, the Rutan Voyager became the first airplane to travel the circumference of the world without landing.
Modern planes are leagues away from the Wright Flyer. They are capable of traveling thousands of kilometers at a time without refueling, carrying hundreds of passengers, and navigating the skies with practically no risk of danger.
So How Do Planes Stay In The Air?
One thing that all planes share is lift. Lift is the force that causes an object to rise into the air. When you jump out of your bed in the morning, you use this force to get yourself airborne.
If you’re standing on the ground, gravity pulls down on you, making it harder to move forward. But if you jump up and push against the floor, then you can overcome gravity’s pull and float upwards.
This is what happens when a plane takes off: it pushes itself upward with more force than gravity is pulling it down with, created by its engines and the design of the plane itself.
Planes generate lift using two different methods. One method is called “wing” lift, where the wings of the plane create lift by creating a large amount of pressure downwards, pushing the plane upwards.
The other method is called “thrust”, where the engines push the plane upwards. Both methods work together to allow a plane to take off.
While thrust is important for allowing the plane to take off, lift is the main force that keeps the plane airborne.
Once the plane has taken off, it will continue flying because of lift. Lift is generated by the shape of the wing, and how much pressure the wing creates.
The shape of the wing means that air flows faster on the top part of it, creating greater pressure above the wing.
This helps the plane to stay stable in the air while also propelling it upwards enough to maintain its flight.
The Wright brothers’ original design used a single propeller to provide both thrust and lift. However, this design proved too inefficient, so they switched to twin propellers instead.
Twin propellers create greater lift than a single propeller, while also helping to balance the plane out.
The move to engines made it easier for planes to generate lift and thrust once technology developed enough to make them practical.
Nowadays, airplanes use multiple large and powerful engines to generate the forces needed to propel the plane through the air.
A combination of lift, thrust, and the design of the planes to optimize both, make it possible for airplanes to stay in the air as long as they have enough fuel to power them.
The development of aircraft has always hinged on one thing – how to get the plane to stay in the air.
With the rise of technologies making it easier for planes to fly long distances at high speeds, the science behind modern flight can seem like magic.
However, it’s really down to the many forces at work and centuries of innovative engineering that makes it possible for airplanes to stay in the air.
