Have you ever noticed how many travel photos feature airplane wings? These wings are more than just cool photo props; they’re incredible feats of engineering! Let’s dive into what makes airplane wings so special and how they help planes soar through the skies.
Airplanes are made up of millions of parts. For example, a Boeing 787 has over 2.3 million parts! Building these flying machines is a huge task. At the Boeing factory, workers drill about 1,000,000 holes to assemble a 747. Airplanes need to be durable, flying for many years and taking off and landing countless times. They also need to be comfortable for passengers.
When you look at an airplane, it might seem like a simple tube with wings. However, attaching the wings is a crucial and complex process. At Boeing’s factory in Renton, Washington, it takes about 12 hours to attach the wings to the airplane’s body. This step is essential because if the wings aren’t attached correctly, the plane can’t move to the next stage of assembly.
The wings are connected to the airplane using around 1,600 bolts, making them a solid part of the plane. Interestingly, the wings are not on the sides but on the bottom of the plane. They are angled slightly upward, a design known as a “dihedral,” which helps keep the plane stable during flight.
Airplane wings come in different shapes, like rectangular, elliptical, swept, and delta. Most commercial jets, like the Boeing 737, use swept wings. These wings reduce drag and perform well at high altitudes, although they need more power to lift the plane.
Modern wings have a backbone called a spar, along with ribs and stringers that give them shape. They also have control surfaces that adjust the wing’s shape to provide more lift or drag. Fuel tanks are often built into the wings as well.
At the tips of the wings, you’ll often see small, flipped-up sections called winglets. These are designed to improve fuel efficiency by reducing the little whirlwinds, or vortices, that form at the wingtips. This helps save fuel, which is important for airlines with many flights.
With a quarter of the world’s airplanes being Boeing 737s, engineers have a lot of data to improve these planes. They are always finding ways to make them safer and more efficient, like adding winglets to save fuel.
Airplane wings are truly amazing, combining complex engineering with smart design to help us travel the world. Next time you see a plane, you’ll know just how much work goes into those wings!
Gather materials like cardboard, paper, and tape to construct your own model airplane wing. Experiment with different shapes such as rectangular, elliptical, and swept wings. Test your models by blowing air over them to see which design provides the most lift. This will help you understand the importance of wing shape in flight.
Simulate the process of attaching wings to an airplane. Use a small box to represent the airplane body and cardboard pieces for wings. Try to attach the wings securely using limited materials like rubber bands or string. This activity will give you insight into the complexity and precision required in real airplane assembly.
Create your own winglet designs using paper or lightweight materials. Attach them to the tips of your model wings and test their effectiveness by observing changes in lift and stability. Discuss how winglets contribute to fuel efficiency and why they are important for modern airplanes.
Take a virtual tour of an airplane manufacturing facility, such as Boeing’s factory. Observe the process of wing attachment and other assembly stages. Reflect on the scale and precision of airplane construction and how each part, especially the wings, plays a crucial role in the aircraft’s functionality.
Research the different types of airplane wings and their specific uses. Prepare a short presentation to share with your classmates, highlighting the advantages and disadvantages of each wing type. This will help you understand the diverse engineering solutions used in aviation.

Every travel picture you see on your friends’ Snapchat might feature a plane wing, but how much do you really know about these mechanical marvels? And what is that little flippy thing? Hey everyone, Trace here for DNews. A Boeing 787 has over 2.3 million parts, and workers on the 747 have to drill 1,000,000 holes during its assembly.
Airplanes are complicated. Aircraft companies are constantly working to update how they design and build these massive machines. They need to fly for decades, take off and land frequently (a 737 takes off somewhere on Earth every 2 seconds), and of course, they need to be smooth and comfortable; that’s important too.
For me, when I see an airplane, I see an aerodynamic tube with wings attached to the bottom. Simple. But in reality, a lot of time and energy goes into ensuring the wing body is attached correctly and that there are zero defects.
That’s Kay Keovongphet, a supervisor at the Boeing 737 manufacturing factory in Renton, Washington. It’s approximately a 12-hour process. The wing body joint is the heartbeat of the final assembly, and if the wings aren’t attached, the airplane doesn’t move to the next flow day. This factory builds 42 airplanes every month—that’s more than one plane every day—but they still spend 12 hours attaching the wings to the fuselage, which is where you sit. That’s how solid they fit in there.
Todd Gray, an engineering team leader at Boeing’s Renton factory, is one of the people in charge of this process. The wings slide into the center wing box and are fastened with about 1,600 bolts. At this point, the two wings and the base of the airplane essentially become a single piece, with the fuselage riding on top of them!
That’s right, the wings aren’t on the side of the plane; they’re on the bottom. And not only are they on the bottom (called a low-wing), but they angle up slightly, which is known as a “dihedral.” Wings with a high dihedral make for a more inherently stable airplane. Basically, if the pilot lets go of the controls, inherently stable planes return to normal flight more easily.
The placement of the wings is also a design consideration—lower wings position engines and wings closer to maintenance, while high wings allow trucks to drive underneath and keep the fuselage close to the ground for easier loading.
While we’re looking at that wing, consider its shape. Wings are designed in a few different configurations: rectangular, elliptical, swept, and delta. According to NASA (the first A is for Aeronautical, after all), the “go-to” for powered jet flight is the swept wing. Swept wings have less drag and perform better at high altitudes, but they require more power to lift the plane. The 737, like most commercial jets, uses swept-wing designs.
Modern airplane wings are similar to historical designs; they have a backbone called a spar, ribs, and stringers to give them shape, along with control surfaces that change the wing’s shape to provide more lift or drag. Additionally, fuel tanks are integrated into the wings.
However, not all wings are created equal. When in flight, air flows beautifully around the wing—except at the wingtip. The tip of the wing creates little vortices, which can reduce efficiency. To combat this, you’ll see wings with flipped-up wingtips, known as winglets, which help maintain upward air pressure on the wing.
These winglets are designed for fuel efficiency, providing an extra few percent of fuel savings for the airplane. With the number of flights these aircraft undertake, that adds up to significant savings for airlines.
Since a quarter of all airplanes in the world’s fleets are Boeing 737s, engineers and mechanics have a wealth of data on the stresses and safety of these airplanes, and they are continually improving! They just started adding winglets to all the planes a few years ago!
