Are plane wings supposed to flex?
Yes, plane wings are designed to flex to varying degrees during flight. This flexing or bending of the wings, also known as wing deformation, occurs due to aerodynamic forces that act on the wings as the plane moves through the air.
During takeoff, climb, descent, and landing, the wings experience varying degrees of lift, drag, and other forces that cause them to deform or flex.
The flexing of the wings is part of the normal behavior of an airplane and is not a cause for concern. In fact, it is a critical design feature that improves the safety and efficiency of modern aircraft.
The flexing of wings absorbs and distributes the stresses that occur during flight, allowing the wings to withstand the forces of turbulence, gusts, and other in-flight disturbances.
In addition to aerodynamic forces, the weight of the plane, its fuel, and passengers also affect the amount of wing flex. More massive planes typically have stiffer wings that do not flex as much as lighter aircraft.
However, some modern planes are engineered to have wings that flex significantly, an example being the Boeing 787 Dreamliner.
Wing flex is a critical design feature of modern airplanes that is necessary for safe and efficient flight. The amount of flex depends on the aircraft’s weight, size, and design. The wings are engineered to withstand the forces of flight without damage or creating any safety concerns.
Therefore, it is perfectly normal and expected for airplane wings to flex during flight.
Is wing Flex normal?
Yes, wing flex is a normal phenomenon in aircraft engineering. Wing flex is the bending of the wings during the flight, caused by various forces such as the weight of the aircraft, the force of lift generated by the wings, and turbulence.
The amount of wing flex varies depending on the type and size of aircraft, speed, and altitude.

Are flexible wings better?
Flexible wings can be better in certain situations compared to rigid wings.
One advantage of flexible wings is their ability to adapt to changing flight conditions. Flexible wings can deform or bend under different loads, allowing for greater control and stability during flight.
For instance, flexible wings can change shape to reduce turbulence caused by gusts of wind or maneuver more efficiently in tight spaces.
Additionally, flexible wings may be lighter and cheaper than rigid wings, due to the absence of stiff materials such as composites or metals. This can lead to lower manufacturing and maintenance costs as well as improved fuel economy.
However, flexible wings also have a few disadvantages. For instance, highly flexible wings may be less efficient at generating lift because they may not maintain the same airfoil shape under varying loads.
This can result in lower lift-to-drag ratio, reduced maximum lift capacity, and also higher stall speeds.
Furthermore, flexible wings have limited structural durability and may be prone to wear and tear over time. The wings can degrade faster due to environmental factors such as moisture, heat, and ultraviolet radiation.
This can pose a greater risk of failure or accidents if not monitored and maintained properly.
Overall, the effectiveness of flexible wings depends on the specific flight requirements and design goals. For some applications such as gliding, soaring, and slow-speed flight, flexible wings can be highly advantageous due to their ability to conform to the flow of air.
However, for high-performance aircraft that require precise control and maximum lift capacity, rigid wings may be the better choice to ensure optimal aerodynamic performance and safety.
Why do planes not fall off wings?
Planes do not fall off wings due to several factors that work together to keep the plane airborne. The design of the plane’s wings is essential to its ability to fly. The wings are designed with a curved shape on top, known as an airfoil, and a flat bottom.
This design creates a difference in air pressure between the top and bottom of the wings, causing lift, which keeps the plane airborne.
Additionally, the plane’s velocity and angle of attack determine the amount of lift generated. Airplane pilots use the control surfaces, such as flaps and ailerons, to adjust the angle of attack and generate lift.
The greater the velocity and angle of attack, the more lift generated.
The weight of the aircraft and the distribution of the weight also play a significant role in keeping the plane airborne. The center of gravity should be positioned in such a way that it is balanced with the lift generated.
If the weight distribution is not balanced correctly, the plane may become unstable and potentially crash.
Lastly, aerodynamic forces, such as drag and thrust, help keep the plane airborne by creating momentum and counteracting gravity. Thrust is the force generated by the engines, pushing the aircraft forward, and overcoming drag to maintain its speed.
The drag acts as an opposing force to the aircraft’s motion, slowing it down and stabilizing its flight.
The design of the wings, the velocity and angle of attack, weight distribution, and aerodynamic forces all work together to keep planes from falling off wings. Without these factors, the plane would not be able to generate the necessary lift to remain airborne and would succumb to gravity.
Are wing seats good on a plane?
Wing seats are considered a popular choice for many travelers, mainly because they offer a great view of the plane’s wings and the sky. Passengers seated in the wing area can enjoy an unobstructed view of the outside world during take-off, cruising, and landing.
However, while the view may be spectacular, some passengers might not prefer the wing seats due to some disadvantages that come with them. Firstly, the proximity to the wing can limit the view of the land below, especially during take-off and landing.
Secondly, some wing seats, especially those nearest to the engines, may experience some noise and vibrations during the flight, which can be disturbing to some passengers.
On the positive side, wing seats are generally considered as the safest seats on a plane. They are positioned in the center of the plane, and in case of turbulence or an emergency, they experience the least amount of movement compared to the seats located at the front or the back of the airplane.
Additionally, wing seats offer a smooth and stable ride, which can be comforting, especially for passengers who are nervous flyers.
Whether wing seats are good or not may depend on individual preferences and priorities. If one values a great view and less turbulence, then wing seats might be the right choice. However, if one is more concerned about noise, vibrations and wants a clear view of the land below, then they might opt for other sections of the plane.
Whatever your choice may be, it is essential to make sure you choose a seat that meets your needs and make your flight as comfortable and enjoyable as possible.

Can a 787 break the sound barrier?
The sound barrier, also known as Mach 1, is the threshold at which an aircraft is said to be supersonic, which is approximately 1,225 kilometers per hour (761 miles per hour) or 340 meters per second.
The Boeing 787 Dreamliner has a maximum speed of approximately 640 miles per hour or 1,030 kilometers per hour, which is less than half the speed required to break the sound barrier.
Moreover, the design of the Boeing 787 Dreamliner has a few limitations that prevent it from breaking the sound barrier. Firstly, the wings of the aircraft were designed to be less swept compared to supersonic planes such as the F-15 or the Concorde.
This design helps the Dreamliner to achieve better lift-to-drag ratio and fuel efficiency. However, this also means that it would require a significant design overhaul to improve the aerodynamics of the plane to achieve supersonic speed.
Secondly, the engines of the Boeing 787 Dreamliner have been designed to provide maximum fuel efficiency, which means they cannot produce enough thrust to push the aircraft beyond its top speed. Hence, changing the engine design to produce more thrust would require new engine designs or modifications in the existing engines, which would significantly increase the weight of the aircraft, and it would not be feasible from a cost perspective.
The Boeing 787 Dreamliner is not designed and built to break the sound barrier. The plane’s aerodynamic limitations and engine design make it impossible to achieve supersonic speeds. The Boeing 787 Dreamliner is designed primarily for fuel efficiency and long-range travel, making it one of the most popular commercial airliners in the industry today.
Why was the wing of aircraft curved?
The wing of an aircraft is curved for a variety of reasons, all of which relate to the fundamental principles of aerodynamics. At its most basic level, the curved shape of an aircraft wing is designed to create lift, or the upward force that allows the plane to stay in the air.
The curved shape of an aircraft wing, also known as an airfoil, is specifically designed to split the airflow around it into two streams: one that flows over the top of the wing and one that flows underneath.
Because of the curve, the air that flows over the top of the wing has a greater distance to travel than the air that flows underneath, creating an area of lower pressure above the wing. This difference in pressure creates lift, which is what allows the plane to fly.
In addition to providing lift, the curved shape of an aircraft wing is also designed to reduce drag, or the resistance that the air exerts on the plane as it moves through it. By reducing drag, planes are able to fly faster, more efficiently, and with greater maneuverability.
The curved shape of the wing helps to smooth the airflow around the aircraft, reducing areas of turbulence and minimizing the resistance that the air exerts on the plane.
There are many different factors that go into designing the perfect wing shape for an aircraft, including its size, weight, speed, altitude, and the specific demands of its mission. Engineers use sophisticated computer modeling and wind tunnel testing to determine the optimal dimensions and curvature for each wing to ensure that it provides the right balance of lift, drag, and stability.
The curved shape of an aircraft wing is essential for providing the lift required for flight and reducing the drag that can slow down a plane. By carefully designing and refining the specific shape of the wing, aircraft designers are able to create planes that are fast, efficient, and capable of handling a wide range of missions and environments.
Why is a curved wing better?
A curved wing, also known as a cambered wing, is better than a straight wing for several reasons. The primary purpose of a wing is to provide lift to an airplane to help it stay airborne. The curved shape of a cambered wing helps to create a pressure difference between the upper and lower surfaces of the wing.
This pressure difference generates lift, which allows the airplane to fly.
When air flows over a curved wing, it has to travel a greater distance over the top than the bottom, which means the air pressure on top of the wing is lower than on the bottom. So, the lift generated by a cambered wing is greater than that of a straight wing.
Additionally, curved wings produce more lift at lower speeds, which is beneficial for many aircraft, such as small planes and helicopters.
Another important aspect of a curved wing is that it helps to reduce drag. Drag is the force that opposes an object’s motion through the air, and it can significantly reduce an airplane’s speed and efficiency.
A cambered wing is designed to reduce drag by creating a smooth and streamlined airflow over the wing’s surface. The curved shape of the wing produces a rolling motion of air molecules that helps to minimize turbulence and drag.
Furthermore, curved wings can also improve an aircraft’s maneuverability. The cambered shape of the wing allows for faster roll rates and tighter turns, which can be critical in certain situations. For example, fighter jets require high maneuverability to perform aerial combat or evade enemy missiles.
Overall, the curved wing is better than a straight wing because it provides greater lift, reduced drag, and better maneuverability. These features are essential in designing and building efficient and effective aircraft for various purposes, including commercial and military use.
Why do some planes wings curved up?
Airplanes are designed with various wing shapes and sizes based on the intended purpose of the aircraft. One such design includes wings that are curved up. These types of wings are called “upturned wings” or “winglets.”
The primary reason for constructing upturned wings is to improve the overall aerodynamic efficiency of the aircraft.
The curved up design of the wings reduces the drag caused by turbulence at the wingtip. Turbulent air is formed when the air moves across the wingtip, which can slow down the airflow and create a lot of disturbance within the air.
This turbulent air causes drag, which is a resistance that holds back the forward motion of the airplane. Therefore, to counteract turbulence and reduce drag, the upturned wings curve upward to minimize turbulence and reduce the drag due to vortex formation at the wingtips.
Upturned wings provide multiple benefits besides reducing drag. The wings, when curved upwards, increase the lift generated by the wings, consequently improving fuel efficiency. The curvature increases the wingspan of the aircraft, which decreases the amount of drag due to the reduced wing loading.
This, in turn, makes it easier for the plane to maintain altitude with less force.
Another benefit of upturned wings is the increase in stability that it provides to the airplane. The extra lift generated as a result of the wing curvature allows the aircraft to glide more smoothly and maintain its altitude, even during gusty or turbulent weather.
The primary reason why some planes have upturned wings is due to their ability to reduce drag, increase lift, and improve the aircraft’s stability, all of which contribute to the aerodynamic efficiency of the aircraft.
These wings are a testament to the various innovations and design techniques that engineers around the world are continually developing to make air transportation more energy-efficient, cost-effective, and environmentally sustainable.
