A ring wing is a wing that effectively has two main planes merging at its ends, so there are no conventional wingtips . Closed-wing concept designs include the annular wing (commonly known as a cylindrical or ring wing), joint wing, box wing, and spiro tip devices:
With the ring wing title, the Lockheed commercial transport would be 52 meters long with a wing circumference of 7.4 meters, the wing itself would be a low average length accessory before arching rearward 27 degrees to join the tail of the aircraft, the total height is substantial up to 23 meters. Lockheed wondered if this concept could also be used for future fighter aircraft , but then they thought: ” Why not make it a little bigger?It’s the 1980s and Lockheed needs a new plane to beat MD and Boeing for the World’s Best Advertising Aircraft Builder trophy. Since then there has been much speculation about the possible physical realization of these as Revolutionary: A ring wing aircraft is a type of aircraft that has circular wings. Circular wings are designed to generate lift more efficiently than traditional wings. This is because circular wings do not generate wingtip vortices, which are a significant source of drag.Here is why it would be this type of airliners would turn out better than the current ones:
For an airplane with ring wings it would be better than a traditional one:
Lift is the aerodynamic force that sustains an aircraft in flight. It is created by the movement of air above and below the wing. Traditional wings generate lift with an arched shape. Air flows faster above the wing than below, creating a pressure difference that lifts the wing. However, traditional wings also generate wingtip vortices. Vortexes are rotations of air that form at the wingtip. They are caused by the separation of the airflow from the wing. Wingtip vortices create drag, which makes it more difficult for the aircraft to fly. Circular wings do not generate wingtip vortices. This is because the airflow always flows around the wing in a laminar fashion. The width of the wing equals its circumference, so the air stream cannot separate. The lack of wingtip vortices makes ring wing aircraft more energy efficient. They can fly at higher speeds on the same amount of fuel as conventional aircraft. They are also quieter and produce fewer emissions. Ring wing aircraft also have a number of other potential benefits, including:
- Greater maneuverability
- Greater impact resistance
- Greater security
However, ring wing aircraft also come with some challenges, including:
- Greater complexity of design and construction
- Higher cost
Some companies are currently developing ring wing aircraft. It is possible that ring wing aircraft will one day become the norm in civil aviation. In this regard, we report below the link to an interesting in-depth video spread on the web:
