What are aerodynamics benefits of using un loadedunloaded wingtips (zero lift),does? does unloaded wingtip make inner parts of wing works more effecientefficient?
(I know that un loadunloaded wingtip reducereduces bending moment,so structural weight can be lower,thus thus reduction in L/D and higher net wing lift (lift minus wing weight), but you can conectconnect wingtip with wire and use elipticalelliptical distribution..so..)
