What is the difference between angle of attack and positive angle of attack?
Angle of attack may be negative or positive - it's simply the angle between the wing chord line and the oncoming airflow. If it's positive then the aircraft will benefit from the lift that is provided, if it's negative then there is no lift (but there's still drag). This is a potentially dangerous situation, unless you wish your aircraft to descend.
What is the transmission angle?
Angle between coupler link and output link for a given crank angle is called transmission angle, it is maximum when crank angle is 180 degree and minimum when crank angle is 0 degree
What is tHe purpose of inlet guide vanes in gas turbine?
In axial flow compressors, the primary purpose of IGVs (fixed or variable) is to guide the airflow onto the first stage rotor blades at an appropriate or required angle of attack.
What is difference between electrical angle and mechanical angle?
Electrical angle is half of mechanical angle in unipolar electrical machines. In multipolar electrical machines, the relationship between the mechanical angle and electrical angle is Electrical angle = (P/2) x Mechanical angle where: P = Number of poles.
What is angle of lap?
the angle of the pulley
What is an angle attack?
The angle of attack is the angle that the kite flys into the air at. The angle depends on the wind seeded in the area you are flying the kite in.
Why high angle of attack is used in fighter air crafts?

What is the angle of attack on an airplane?
The angle of attack is an aerodynamic term which refers to the angle between the mean wing chord of the airfoil and the direction of airflow. This is different from the pitch angle of the aircraft in that the pitch angle refers to the aircrafts position in relation to the horizon, whereas angle of attack refers to the aircrafts angle in relation to airflow.
How does angle of attack affect lift and drag?
A higher angle of attack has an increase of both lift and drag.
What is the difference between the angle of attack and angle of incidence?
Zero degrees.
What is the angle between the airplanes wing and the direction of airflow called?
The angle between the airplane's wing and the direction of airflow is called the angle of attack. This angle is important for generating lift and controlling the aircraft's flight.
What is the point at which lift starts to drop off?
This is termed the Critical Angle of Attack and represents a maximum in the Lift Coefficient vs. Angle of Attack curve. If the angle of attack is increased beyond this point, the wing will stall. For most airfoils, the critical angle of attack is around 15 deg. For swept back wings it is typically higher.
What control stall margin?
Stall margin is the difference in the critical angle of attack and the angle of attack in which you are operating.Example:Suppose, critical angle of attack= 15°AOA operating in a flight= 5°then, Lift by the wing balances the weight of the airplane with a STALL MARGIN= 10°Stall Margin is being controlled by an angle of attack and the position of flap control..CHEERS!
How does the angle of attack affect the accuracy of attack in fencing?
the steeper the angle of attack the easier it is for your opponent to pare' your thrust or lunge. the steeper the angle of attack, the less your thrust is lined up with your line of sight, giving a larger emphasis on depth perception in the attack, and in a stressed, rushed situation, that often results in the touch being either high or low.
What will happen to the boundary layer when the angle of attack increases?
When the angle of attack increases, the boundary layer will thicken and separate from the surface of the airfoil earlier, leading to increased drag and reduced lift. This can eventually lead to flow separation and stall if the angle of attack is too high.
The upward angle of the wing is called the?
angle of attack. It is the angle between the chord line of the wing and the oncoming airflow. A higher angle of attack generates more lift but also increases drag.
What is the difference between the Angle of Attack and th Angle of Incidence?
Hi!The angle of incidence is built into the aircraft, and cannot be changed. This angle is the angle that the wing makes with a level surface (such as if the ground if the aircraft were parked).The angle of attack (commonly abbreviated AoA), is the angle that the chordline of the airfoil makes with the relative wind. So if you were in straight and level flight, maintaining altitude, the angle of attack would be zero degrees.When an aircraft exceeds a critical angle of attack (which is determined by the design of the airplane), the airflow will peel off of the wing, causing the wing to stop producing lift. The aircraft is, in this scenario, stalled.Hope this helps.Source(s):PPL ASEL 6/17/08
