Airplanes Store Fuel In Their Wings For 6 Reasons
An airplane is a fixed-winged aircraft with a powerful engine capable of lifting it and propelling it ahead. It comes in a wide range of shapes and sizes, and it’s rather impressive. While fighter jets and other small planes store gasoline behind the pilot’s seat, huge planes like the Boeing 747 store massive amounts of fuel beneath their wings.
By far the most popular type of fuel storage in an airplane today is integral tanks in the wings (sometimes known as “wet wings”). Rather than putting a separate gasoline container inside the wing, this method makes use of the aircraft wing structure as a fuel tank that is sealed from the outside environment.
The Six Reasons Why Airplanes Store Gasoline In Their Wings Are Listed Below.
1. The wing is an ideal place to store fuel for a light aircraft because the electrical and hydraulic components required to control the ailerons and flaps only take up about 10% of the available space.
2. Because wet wings don’t require a tank, they save the manufacturer a lot of money. Maintaining huge tanks and bladders takes time, which affects the aircraft’s overall payload capacity.
3. Fuel storage would have been much better suited to the stiffer wing structures. The gasoline for the left engine comes from the left wing, and vice versa. The advantage of storing fuel in the wings is that gravity-based feeding is possible. The engines will continue to be supplied by gravity in the event that the gasoline pumps fail or malfunction. In addition, “center tanks” are frequently installed in the belly of modern airplanes. Gravity feeding is not a possibility because this reserve is placed beneath the engines. Gravity feeding will always be feasible as long as there is gasoline onboard, due to the depletion of this fuel first.
4. The plane’s center of mass is near the plane’s wings. Too much weight in either direction will cause performance issues or even cause the plane to tip over on the tarmac. Fuel should be stored in the aircraft’s center to maintain a steady COG throughout the flight. If the fuel was stored towards the aircraft’s nose or tail, the momentum shift would be much higher. When there is a deviation from the center of gravity, stability and controllability are impaired.
5. The term “flutter” may be endearing when applied to butterflies, but it is terrifying when applied to airplanes. Airflow across the wings causes a “unstable, self-excited structural oscillation,” according to the description. Surfaces of airplanes vibrate so much due to atmospheric conditions that they finally break. Avoiding this is one of the most important reasons for storing fuel in the wings.
6. If the aircraft’s weight, including fuel, is concentrated in the fuselage, the wing root bears the brunt of the load. This puts a lot of strain on the plane’s structure in the long run, reducing its fatigue life. Because the wings are less prone to flex upwards due to the increased stiffness that comes from storing fuel in the wing, more weight may be carried and less maintenance is required.
