The aircraft's wings are where fuel is kept. There are a few causes.
Because fuel is one of the heaviest parts of an airplane, the primary motivation is to balance the weight. Fuel may make up as much as one-third of the gross weight of the airplane on certain lengthy journeys. If this additional weight were stored in the fuselage, less cargo room would be available, and the aircraft's structure would be under more stress. A large amount of the weight is brought directly to the source of lift when fuel is loaded into the wings, which lessens the pressure on the wings during flight and distributes the load more evenly throughout the airframe.
Additionally, gravity feeding—which enables gasoline to reach the engines without the need for pumps in the event of a malfunction—is made possible by storing fuel in the wings.Fuel tanks in the wings, especially when full, give the aircraft strength and stability during takeoff, therefore this is another reason to counteract stress. When the tanks are full, the wings become more stiff and the aircraft's total takeoff weight is distributed more evenly. As the airplane accelerates down the runway, this aids in keeping the wingtips level and down to balance the disproportionately heavy fuselage.
Additionally, it lessens wing flutter. The phenomenon known as "wing flutter" occurs when aerodynamic forces cause the wings to vibrate. If not adequately regulated, this may result in damage or possibly the failure of the wing structure. A clever and effective method of making good use of available space, balancing weight, reducing stress, and reducing wing flutter is to store fuel in the aircraft's wings. Because it does away with the need for bulky tanks or bladders that require constant maintenance and have a limited cargo capacity, it also saves money for manufacturers and airlines.
