What part of the plane generates lift?
wings
Lift is generated by every part of the airplane, but most of the lift on a normal airliner is generated by the wings. Lift is a mechanical aerodynamic force produced by the motion of the airplane through the air.
How does an airplane get its lift?
Airplane wings are shaped to make air move faster over the top of the wing. When air moves faster, the pressure of the air decreases. So the pressure on the top of the wing is less than the pressure on the bottom of the wing. The difference in pressure creates a force on the wing that lifts the wing up into the air.
What is the equation for lift?
The lift equation states that lift L is equal to the lift coefficient Cl times the density r times half of the velocity V squared times the wing area A. For given air conditions, shape, and inclination of the object, we have to determine a value for Cl to determine the lift.
How does the shape of the fuselage affect lift?
The shape of the fuselage can even create lift. In fact, the shape of the fuselage can create enough lift that the aircraft doesn’t need wings. These are three different lifting body designs that NASA tested while studying reentry vehicles. Notice the complete lack of wings to provide lift.
What is the difference between tube-body and lift-body aircraft?
Lift-body design uses the body of the aircraft in the shape of an airfoil thereby providing lift from the body which added to the lift from the wings. A conventional tube-body aircraft gets its lift from only its wings which make up about 15\% of its structural weight.
How do you create lift in an airplane?
All that is necessary to create lift is to turn a flow of air. An aerodynamic, curved airfoil will turn a flow. But so will a simple flat plate, if it is inclined to the flow. The fuselage of an airplane will also generate lift if it is inclined to the flow.
What are wing fuselages?
Wings are, after all, planks, with carefully sculpted shapes called airfoils. NASA’s Lifting Body experiments, and the Space Shuttle, are examples of fuselages specifically designed for lift.
