Aircraft fuel tanks are a major component of aircraft fuel systems. They can be classified into internal or external fuel tanks and can be further classified by method of construction or intended use.
Aircraft using integral fuel tanks normally have sophisticated fuel systems that include in-tank boost pumps. There are usually at least two pumps in each tank that deliver fuel to the engine(s) under positive pressure.
In most large aircraft, the fuel is stored in the wings, although some aircraft also have tanks in the center body, or the center fuselage, called center tanks. Additionally, widebody aircraft have extra tanks in the tail or the horizontal stabilizer, which are used to control the center of gravity of the aircraft during long-haul flights.
Fuel Tanks. Aircraft fuel tanks are subjected to vibration, aerodynamic forces, heat, cold, inertial loads, and even lightning strikes during typical operation. The tanks must be designed to withstand all these forces, and not deform under any loading in the design envelope.
Small piston-engine powered aircraft often have a single-tank fuel system. On newer aircraft, two fuel tanks, with one in each wing, are more common. A two-tank system requires additional components to allow controlled provision of fuel to the single engine.
Fuel tanks are a vital component of an aircraft’s fuel system. They store fuel on the aircraft, typically in the wings, fuselage, or both. Modern aircraft utilize different types of fuel tanks, such as integral tanks (part of the aircraft structure) and bladder tanks (flexible fuel containers).
Aircraft fuel tanks are critical components that play a vital role in the performance, safety, and efficiency of any aircraft. These tanks are designed to store and supply fuel to the engines during flight, and their design specifications significantly impact the overall operation of the aircraft.
There are three basic types of aircraft fuel tanks: rigid removable tanks, bladder tanks, and integral fuel tanks. The type of aircraft, its design and intended use, as well as the age of the aircraft determine which fuel tank is installed in an aircraft.
The fuel system in the aircraft that you fly has one purpose: Delivering a steady flow of fuel from the tanks to the engine so it doesn’t miss a beat, regardless of power settings, the aircraft’s altitude, or attitude.
Fuel Tanks: The fuel tanks, normally located inside the wings of an airplane, vary in construction by aircraft, but generally use aluminum, a "wet-wing," or flexible bladders. Tanks will have a filler opening on top of the wing through which they can be filled.
