Drag Fly
Do the wiglets on the new airliners reduce drag, and if they do how much. example 737 or 747?
I heard from a pilot that this can increase the range on some planes so they can fly longer routs. Example 757 can fly trans atlantic with them.
Winglets reduce parasitic drag and improve fuel efficiency by up to 6%.
To say that something increases lift and does not reduce drag is erm… not a good statement. The increase in lift at the same air speed allows for a tiny reduction in pitch and drag. So while reduction in drag is not the direct effect it is a side effect and it is the side effect for which the winglets are added.
Another way of looking at it is that they reduct the energy used to create the wingtip vortices, but the vortices are created by the higher pressure air under the wing tip wrapping around to the low pressure area above the wing tip… which reduces lift and increases parasitic drag.
Another way of solving the same issue is to sweep back the win tips.
(below) No, they reduce the wingtip vortex. Anything the aircraft does that doesn’t result in it moving forward, including making noise and pretty twisty patterns in the air, results in higher energy consumption and less efficient opperation. Wing tip vortices are bad, not good. They are an expression of lost energy.
