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.
What else can I help you with?
Why were wings swept back in an airplane and what advantage does it have over non swept back wings. in English please. for example it reduces drag and increases speed or something in simple form?
1. swept back wings are contributes to more lateral stability, 2. swept back wings produce less lift, so in turbulent weather they are less susceptible to abrupt changes, 3. They are designed with low thickness and high fineness ratio, hence less form drag, 4. genarally they are tapered, so less induced drag, 5. Capable of flying at high mach no. as actual relative wind speed is at an angle to the wing leading surface and therefore the wind component perpendicular to the wing leading edge is less, and hence the wing senses less speed than actual. so they can fly to high mach no.'s. if a straight wing is changed into a swept back wing similar parameters of area,aspect ratio, taper,section and washout, the CL is reduced. this is due to premature flow separation from the upper surface at the wing tips. suppose sweep angle of 45 degree CL reduced 30%
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.
How do you reduce drag?
To reduce drag, you can: Streamline the shape of the object to minimize resistance. Smoothen the surface to reduce friction. Eliminate unnecessary protrusions or features that contribute to drag.
What are the ways to reduce drag?
To reduce drag, you can streamline the shape of the object, minimize surface roughness, and reduce the frontal area exposed to the flow of air or water. Additionally, reducing speed can also help decrease drag forces.
How are airplanes designed to reduce drag?
Airplanes are designed to reduce drag by incorporating streamlined shapes and smooth surfaces to minimize air resistance. Winglets at the end of wings help reduce the formation of vortexes that create drag. Advanced materials and coatings are also used to reduce skin friction drag on the aircraft's surface.
What is Advantage of swept back wing?

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.
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.
How does drag affect a paper airplane?
Drag effects paper airplane just as it affects anything else that moves. It is either parasitic or induced on paper airplanes. Drag may reduce a paper airplanes speed and/or range.
Are airplanes designed to reduce or increase drag?
Airplanes try to reduce drag so they can cut back on fuel costs, and shave time off their route.
Induced drag in airplane is reduced by?
winglet
What is zero lift coefficient of drag?
For no lift, The induced drag will be zero. However, there will still be drag due to viscous forces and pressure forces.
How do you reduce drag?
To reduce drag, you can: Streamline the shape of the object to minimize resistance. Smoothen the surface to reduce friction. Eliminate unnecessary protrusions or features that contribute to drag.
Why are aeroplanes shaped the way they are?
To produce lift with the least amount of induced drag.
Why are planes wings different shapes when looking from above?
Wings that are straight-edged are stable at low airspeeds. However, they produce a lot of drag and limit the airspeed. Wings that are swept back have less drag and are capable of greater speed, but they are unstable at low speed.
