seems to have "reinvented" quite a lot, right?
von Hoerner, some others worked ahead of Whitcomb afaik.
( Theoretical understanding of area rule, remedial shock bodies started in WWII.)
True enough, but then why weren’t they used earlier than the Learjet application. We didn’t winglets on, say, the Trident or the 727, 737 until long after the WW II experiments. If there had been an application on a German or European jet airliner design, I haven’t seen it.
basic idea was floated around/before WWI ?
fuel was cheap ( we had box carriers with gas turbine propulsion (gen3) that cruised faster ( 27..30kn ) than most warships
more happened in the glider domain. academics and smallish commercial.
For gliders anything that reduces drag is welcome.
I'd like to see a comparison of the various types versus the window of usefulness.
Argument I seem to remember was that winglets, fences, endplates, ... each peak ( or have wider scope of usefulnes ) in different segments of flight regime.
Even between B winglets ( how brilliant to homestead a generic term ) and A sharklets seem to exist differences in profiling though the basic shape seems to be first blush similar.
Another interesting domain is belly fairings. ( historic evolution but also solutions like the recently available SHARP modification for better short field performance on A320. Look ma, no moving parts
