What is Hoerner wing tip?
Hoerner was a pioneer researcher in the field, having written a technical paper published in 1952 that called for drooped wingtips whose pointed rear tips focused the resulting wingtip vortex away from the upper wing surface. Drooped wingtips are often called “Hoerner tips” in his honor.
What are the upturned wingtips called?
They’re called winglets, and their purpose is to reduce turbulence at the tips of an airplane’s wings. The air pressure on the bottom of a wing is greater than the pressure on top, so when air flowing across the two surfaces meets at the wing tip, it forms a vortex-a miniature tornado.
What are curved wingtips called?
Winglets, the curved surfaces at the wingtips, essentially make it easier for a plane to cut through the air. Winglets have been around for decades, but most passengers probably haven’t taken the time to find out what purposes they serve or how they came to be.
What do upturned wingtips do?
Winglets allow the wings to be more efficient at creating lift, which means planes require less power from the engines. That results in greater fuel economy, lower CO2 emissions, and lower costs for airlines.
What is a raked wingtip?
Raked wingtips, where the tip has a greater wing sweep than the rest of the wing, are featured on some Boeing Commercial Airplanes to improve fuel efficiency, takeoff and climb performance. Like winglets, they increase the effective wing aspect ratio and diminish wingtip vortices, decreasing lift-induced drag.
Why is a curved wing better?
Airplanes’ wings are curved on top and flatter on the bottom. That shape makes air flow over the top faster than under the bottom. As a result, less air pressure is on top of the wing.
What do curved wingtips do?
Curved wingtips can offer a higher level of wing flex, allowing it to adapt to changing air pressure levels.
Which wing tip shape is more aerodynamically efficient?
Elliptical Wing The elliptical wing is aerodynamically most efficient because elliptical spanwise lift distribution induces the lowest possible drag.
Why are wingtips raked?
Why does the 777x not have winglets?
Why does the 777 not have winglets? One reason that the 777 does not feature such wingtip extensions is the operational limits these would place on the aircraft. The 777-200LR and -300ER variants of the aircraft have a wingspan of 64.8 meters. This only just falls below the upper limit for the ICAO’s aerodrome code E.
Why are elliptical wings better?
An elliptical planform is the most efficient aerodynamic shape for an untwisted wing, leading to the lowest amount of induced drag.

Can I use my existing navigation light on this wing tip?
This wing tip has a flat nav pad for a standard navigation or navigation strobe assy. If you chose to use your existing nav light you will need to replace the aluminum cover that holds the navigation or navigation strobe assy in place. The three options for covers are on our web site here:
