Why are wings mounted sometimes on top of the fuselage instead of the bottom?

When the wing of an aircraft is located above the fuselage, the aircraft is generally considered more stable. High-wings increase stability in roll. It does not significantly affect stability in pitch and yaw; for those appropriate tail design is needed.

Why do some planes have wings on top and some on bottom?

Many short-takeoff-and-landing aircraft have high wings because they are designed for utility work on unimproved strips; a high wing is farther from the bushes, and a low fuselage is easier to load with cargo.

How are airplane wings attached to the fuselage?

The wings are attached to the main fuselage body using a lug. The bending moment and shear loads from wing to the fuselage structure is transferred through the lug structure. The attachment is done by series of pinned lug between wing side of wing box and fuselage.

Why are Cessna wings on top?

High-wing airplanes give pilots and passengers a better view of the ground below the aircraft. This is especially true of 4-seat and larger planes, where there is less a chance of a wing blocking your view. Low-wing airplanes allow for a better view above the plane thanks to the wings being below the fuselage.

Why do cargo planes have wings on top?

Placing the wings on top of the fuselage allows the bottom of the fuselage to be closer to the ground. This is less of a problem for airlines. Commercial cargo can usually count on ground equipment for loading and unloading cargo containers on aircraft.

What is the main purpose of the fuselage?

fuselage, central portion of the body of an airplane, designed to accommodate the crew, passengers, and cargo. It varies greatly in design and size according to the function of the aircraft.

Why are cargo planes wings on top?

Which wing generates the most lift?

Each wing was tested 20 times. It was concluded that Airfoil Three generated the most lift, with an average 72 grams of lift. Airfoil One generated the second most lift with an average of 35 grams.

How are airplane wings held on?

The outboard hinged part of the wing is called the aileron; it is used to roll the wings from side to side. Most airliners can also be rolled from side to side by using the spoilers.

What is the primary structure of the fuselage?

The fuselage of a transport aircraft is a cylindrical shell consisting of the skin, longitudinal stringers and longerons, and transverse frames and bulkheads.

What type of wing produces the most lift?

Airfoil Three generated the most lift due to the oval arc shape. Lift is caused by the faster movement of air on the top side of an airfoil.

Where are the wings of an aircraft attached to the fuselage?

The wings of an aircraft can be attached to the fuselage at the top, mid-fuselage, or at the bottom. They may extend perpendicular to the horizontal plain of the fuselage or can angle up or down slightly.

How does the weight of an airplane engine affect its wings?

In cases where the engine is attached to the wing — which are often — the weight of the engine also acts on the wing when it is on the ground. When in flight, the shape of the wing (commonly called airfoil) allows it to generate lift.

What forces act on airplane wings when they are on the ground?

When on the ground, the only two forces acting on the wings are the weights of the wing itself and that of the fuel in it. In cases where the engine is attached to the wing — which are often — the weight of the engine also acts on the wing when it is on the ground.

What gives rise to a bending moment in a plane?

The action of the two weight forces gives rise to a bending moment. As expected, the forces acting on a plane’s wing are different when it’s on the ground from when it’s flying in the air. When on the ground, the only two forces acting on the wings are the weights of the wing itself and that of the fuel in it.
