Why is fuel stored in wings?
Fuel acts as a counter stress for the wings shortly after take-off when the stress of the aircraft mass acts on them (during take-off it is always the largest). This prevents a large change in the wing dihedral angle. In bigger aircraft, leaving the wing tanks empty might result in wings simply snapping off.
What is stored in the wings of a plane?
Fuel
Why is Fuel Stored in the Wings? There are several reasons fuel is stored in the wings but the main three reasons are to balance weight, counter-stress and reduce wing flutter.
What are the components of wing structure?
The principal structural parts of the wing are spars, ribs, and stringers. [Figure 2-7] These are reinforced by trusses, I-beams, tubing, or other devices, including the skin. The wing ribs determine the shape and thickness of the wing (airfoil).
Do planes carry fuel in their wings?
On passenger planes, fuel tanks are often integrated into the wings, and when there are also tanks inside the body of the aircraft, the wing tanks are used preferentially. The placement reduces the stress on the wings during takeoff and flight, by putting the heavy fuel directly inside the source of lift.
Why are fuel tanks located in the wings?
This provides the space needed to store fuel. On a conventional aircraft, placing fuel tanks in the wings places the fuel mass very close to, or on, the center of lift. This dramatically reduces Cg shift during flight and reduces the size and weight of the tailplane to maintain stable flight.
Why are the wings of an airplane so thin?
Airplane wings are designed purely from aerodynamic and structural considerations. Supersonic fighters often have much thinner wings (and store fuel in the fuselage) because those are the requirements of supersonic flight.
Why are wings designed to carry the most weight?
The simplest explanation is that the wings are designed to be the load bearing structure in the air and on the ground. So, you want the most weight to be in/on the wings. In other words, you want to keep the weight stress on the wing structure as opposed to the fuselage because the wings are designed to carry weight.
How is the thickness of a wing determined?
The wing thickness is primarily dictated by structural demands. It has to provide an aerodynamic fairing for the wing spar. Making it thinner would drive up the mass of the structure inside. To simplify things, imagine the wing spar as an I-beam.
