The wing twist angle is introduced to prevent stall from occurring at the wing tip before than the wing root. Usually wings are 'washout' twisted, resulting in a decreasing angle of attack starting from the root and towards the tip. Precisely, the twist angle is the angle between the zero-lift line of the profile in the current section and the zero-lift line of the root profile. As the twist angle increases along the span, the lower is the local angle of attack and the lower is the lift generated. By this we prevent the wing tip from generating as much lift as the wing root, which may cause the stall to occur at the worst place we'd like it to occur, the ailerons. By washout twist, we obtain to make stall occur at the wing root, without lost of ailerons control.

How is an airplane wing designed to lift the airplane.?
If straightened out, the top surface of the wing is longer than the bottom one. When air flows over the wing, it must travel faster over the top of the wing so there is less air pressure. higher air pressure on the bottom and lower air pressure on the top= LIFT. The higher the Airspeed the lower the air pressure is called Bernoulli's principle.
What are the side effects of Hemophilia?
This is a rather tricky question. The best answer is that it truly depends and the person. Often a "carrier" is affected by it to some degree. Factor level tests frequently show a carrier's factor levels are somewhat lower than normal. To actually be considered a hemophiliac or a "symptomatic carrier" that factor level would need to fall below 50%. The short answer is yes, there can be. The effects are often similar to the effects of mild to moderate hemophilia.

What is wing twist?
Wing twist is the change of the angle of incidence of the airfoil, along the span of the wing. This is also called wash out if the wing tip has a smaller or negative angle compared to the wing root, or wash in if the wing tip angle is bigger. Wash out is added to wings to ensure the wing tip stalls first, which makes flying behaviour more predictable and low-speed flight more controllable. For a similar reason, wing tips usually have a shorter airfoil chord than wing roots.
How does the angle of attack affect the amount of lift?
Inclination Effects on Lift. As a wing moves through the air, the wing is inclined to the flight direction at some angle. The angle between the chord line and the flight direction is called the angle of attack and has a large effect on the lift generated by a wing.
The upward angle of the wing is called the?
The upward angle of the wing of an aircraft is the dihedral angle. It is vital because it keeps the plane from unexpectedly rolling while in flight.
Why is there a twist in a propeller blade?
to keep the angle under which propeller section sees the relative velocity. Because, a propeller essentially is a wing which rotates around an axis parallel to the flight velocity. wings operate best at a certain angle of attack, which is an angle at which wing 'sees' the flow. now, propellers rotate and tangential velocity increases from root to tip. airflow velocity is obviously constant. tangent of angle between relative velocity and prop section is air velocity / tangential velocity. we want angle between propeller section and relative velocity to constant, since tangent changes from root to tip , we need to change angle of propeller section itself.
What should be the design of an helicopter wing?

What is sweepback?
the angle at which an aircraft's wing is set back from a right angle to the body
What is an angle of attack?
An angle of attack is the angle between the chord line of an airfoil and the airflow over it.
What is the angle between the airplanes wing and the direction of airflow called?
This is called the "angle of attack."
What will be the pressure below the surface of the wing of the plane flying in the air?
It depends on the angle of attack of the wing.
What is decalage on a bi-plane?
Decalage on a fixed wing Biplane aircraft is the angle difference between the upper and lower wings of a fixed wing Biplane aircraft, i.e. the acute angle contained between the chords of the wings in question.The decalage is said to be positive when the upper wing has a higher total angle-of incidence than the lower wing, and negative when its total angle of incidence is lower. Positive decalage results in greater lift from the upper wing than the lower wing, the difference increasing with the amount of decalage.Uncle Fudd
