Closed wing - Wikipedia
WebDec 28, 2024 · It featured a cylindrical-wing design surrounding the main airframe, rather than traditional wide, flat wings. It never quite took off. … A closed wing is a wing that effectively has two main planes which merge at their ends so that there are no conventional wing tips. Closed wing designs include the annular wing (commonly known as the cylindrical or ring wing), the joined wing, the box wing and spiroid tip devices. Like many wingtip devices, the … See more Wingtip vortices form a major component of wake turbulence and are associated with induced drag, which is a significant contributor to total drag in most regimes. A closed wing avoids the need for wingtips and thus might be … See more Pioneer years An early example of the closed wing was on the Blériot III aircraft, built in 1906 by Louis Blériot and Gabriel Voisin. The lifting surfaces comprised two annular wings mounted in tandem. The later Blériot IV replaced the … See more • Filippone, Antonio (September 2006). "Non-Planar Wing systems".
