Why are there no forward swept wings?

This is because forward sweep also has a disadvantage. When an airplane turns and applies high G-loads on forward-swept wings, their tips bend upward and, as they do, the leading edges twist upward too, increasing the angle of attack. If the twist goes too far, the wing fails structurally; that’s bad.

Why don’t we use flying wings?

I think the other answers cover a lot of the pros and cons fairly well, but in my experience the primary reason flying wings aren’t commonly used is that they do not provide enough internal volume for passengers or payload.

Why did old planes have two wings?

Biplanes were the original aircraft design in aviation to provide a lightweight yet sturdy structure. Newer materials and designs are much stronger and can be built with one wing. Having two wings stacked on top of each other also meant that the wings have twice the area so this allowed for the span to be shorter.

Why do propeller planes have straight wings?

Straight wings are better for lower velocities and swept wings are better for higher, near-transonic velocities. , Retired now, but was in aerospace for over 30 years, mechanics, inspection and mainly project management. Swept wings are more efficient at higher airspeeds than most prop planes can fly at.

What is the point of forward swept wings?

Forward-swept wings make an aircraft harder to fly, but the advantages are mainly down to manoeuvrability. They maintain airflow over their surfaces at steeper climb angles than conventional planes, which means the nose can point higher without the aircraft going into a dangerous stall.

Can a wing fly without any body?

There is no way any aircraft should fly with essentially all of one wing missing. However, part of the F15’s lift comes from the shape of the engine intakes and fuselage.

Why are biplane wings staggered?

It’s called a staggered wing and is done to reduce aerodynamic interference between wings in certain circumstances. A wing with positive (forward) stagger is most common because it improves both downward visibility and ease of cockpit access for open cockpit biplanes.

Can a plane fly with half a wing?

No, an airplane cannot fly with only one wing. With only one wing, the weight is shifted to one side of the plane. This makes it impossible to balance. There have been instances in history where pilots had to improvise when their planes lost one of their engines.

Why can a swept wing aircraft go faster?

A swept wing is the most common planform for high speed (transonic and supersonic) jet aircraft. In transonic flight, a swept wing allows a higher Critical Mach Number than a straight wing of similar Chord and Camber. This results in the principal advantage of wing sweep which is to delay the onset of wave drag.

Why do swept back wings stall at the tip?

Because the swing is swept backwards, the lines of equal pressure are swept back too, which creates a pressure gradient that draws the boundary layer toward the wingtips, making it thicker, while making it thinner towards the root. The thicker boundary layer has the tendency to stall first.
