What causes induced drag?

Induced drag is caused by the creation of lift on an aircraft's wings. As the aircraft generates lift, it creates vortices at the wingtips, which result in a rearward force component known as induced drag. This drag increases as the angle of attack or lift produced by the wings increases.


Why drag increases as lift increase - for helis?

As lift increases for helicopters, the angle of attack of the rotor blades must also increase to generate more lift. This higher angle creates more drag due to increased air resistance and turbulence. Additionally, the higher lift forces can lead to increased induced drag, which is generated as a byproduct of producing lift.


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.


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 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.


What are the amounts of lift and drag for a airplane?

The amounts depend on the airplane's size, shape, speed, altitude, and angle of attack, among other things.


Is lift produced by the angle of attack?

Yes, lift is primarily produced by the angle of attack, which is the angle between the wing's chord line and the oncoming airflow. As the angle of attack increases, the airflow over the wing changes, creating a pressure difference between the upper and lower surfaces, which generates lift. However, if the angle of attack becomes too high, it can lead to stall, where lift decreases sharply. Thus, maintaining an optimal angle of attack is crucial for effective lift generation.


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 induced drag aslo called lift drag?

Induced drag is the name given to the force of drag 'induced' by the act of increasing lift. Induced drag is directly related to how much lift the wing is producing, and usually angle of attack induced drag is usually caused by flow separations at high angles of attack and wing tip vortices, which is the main form of induced drag. Delta wings have massive induced drag because of their high chord which presents a high frontal area at high angles and leading edge vortices used to produce lift at low speed which generate lots of drag. At high speed and low angle however, the leading edge vortex no longer occurs and the wing has a very low frontal area which decreases the induced drag to almost nothing. Unlike other forms of drag, induced drag actually decreases with higher speed.


How does swept back wing reduce induced drag?

A swept back wing reduces induced drag by allowing the wing to better distribute lift across its span. This helps to minimize the formation of turbulent wingtip vortices which contribute to induced drag. Additionally, the sweep angle reduces the effective angle of attack at the wingtips, which further reduces induced drag.


How far does aircraft wing lift up when in flight compared to at a standstill?

Aircraft wings lift up to a higher angle of attack in flight compared to when at a standstill. This increase in angle of attack creates the necessary lift force to keep the aircraft airborne. At a standstill, the wings are typically kept at a lower angle of attack to help reduce drag and improve efficiency.


What does the term angle of attack in birds mean?

It is simply the angle that the wing of the bird is to the incoming air force. This term is used when the birds are gliding or not flapping their wings. A change in this angle can cause the bird to be either more streamlined, cause lift, drag or even descent.
