Boeing has announced the use of new winglets on the Boeing 737 Max.   “Boeing has unveiled a new Advanced Technology winglet design concept for its 737 MAX family which the manufacturer says will provide customers with up to an additional 1.5 per cent fuel-burn improvement, depending on range, on top of the 10 to 12 per cent improvement it is already claiming for the new 737 variant.”

Here is a paper airplane with the advanced technology winglet.  It uses the barnaby platform traditionally made:  The leading edge is folded over repeatedly to make a thick leading edge.  I then cut out the wingtips and split them with a scissors.  They are still multiple sheets of paper, so they are wrapped with magic tape to keep the layers together.

A close-up.  The difference between advanced technology and split blended winglets:  split blended winglets are staggered on the wingtip, and advanced technology winglets are stacked.  Split blended winglets are curved, and advanced technology winglets are straight.  This implementation of advanced technology winglets has them curved.

And here is the straight version.  The lower winglet is shorter.
