A wing that does not have any external struts or bracing. All assistance is provided by the wing itself. The wing spars are designed to handle all of the torsion and bending stresses. They do this by having a slightly curved profile, with the tips of the spar meeting at a sharp point called the tip of the wing.
Cantilever wings are very light and can be made out of thin sheet metal. This allows them to create much more lift per unit area than conventional wings. As a result, cantilever wings can be smaller for a given power requirement. They also require less material per unit area than conventional wings, which makes them cheaper to produce.
Cantilever wings were first used by Orville and Wilbur Wright in their early flying machines. These wings were made from wood and weighed almost half as much as the entire aircraft. However, they produced so much force when moving through the air that they had to be mounted on a frame structure to keep them from breaking off.
Since then, cantilever wings have been used in many different types of vehicles including airplanes, helicopters, and hovercraft.
The main advantage of cantilever wings is their ability to generate large amounts of lift for their weight.
They do this by having very little mass, so they can bend easily in strong winds when under load.
The term "cantilever" is used for describing a style of construction where one end of the main supporting body is free to move (i.e., not attached to anything else) while the other end is fixed in place. Thus, the name "cantilever" means "to be able to bend". For example, the wing of a plane is called a "cantilever" because it can bend freely at one end while being fixed at the other. Aircraft engines also use this design technique; the engine block is the fixed part of the unit while the cylinder head is the free-floating part that connects to the rest of the aircraft through a drive shaft.
Cantilevered structures are often used as airfoils because they tend to have low drag when flying level or even slightly canted to one side. This is because there is no need for any trailing edges on the wings, just an upwardly angled tip section, which acts like a small tail surface.
Wings are frequently designed with a complete cantilever. This implies they are constructed in such a way that no external bracing is required. They are internally supported by structural components that are aided by the aircraft's skin. The word "cantilever" comes from the French for "wayward post". Because there is no support underneath a complete cantilever wing, it has a tendency to bow outwards under its own weight. This can be prevented by adding stiffeners to the underside of the wing which act as stay-braces.
The first practical use of the complete cantilever design was in the World War I era and was done by Billy Mitchell. He created a series of drawings for an airplane that used this type of wing; these designs were later adopted by the Army for their Vickers Vimy helicopter. The Soviet Union also developed cantilever wings for their helicopters during this time period.
After World War I, complete cantilever wings fell out of favor because they were too expensive to build. The next major development in wing design came about when Charles Lindbergh published his book "Wings", which described his experience building a single-seater monoplane using a cantilever wing. His design was very successful and led to many other single-seater airplanes being built with this type of wing.
Because the drag penalty of external wing bracing is high for their task, the bulk of modern aircraft have cantilever wings. The spars, ribs, and skin work together to produce a lightweight, torsionally strong box structure (commonly called the wing box). External support is provided by spanners or struts attached to the top and bottom of the box structure. The spars are usually made from aluminum or titanium, with thick sections at the roots where they attach to the fuselage. They may be straight or slightly curved, with clean terminations at each end. The leading edge of the wing is swept back (sloped outward) to increase its air speed when moving through the air.
Cantilever wings are the standard design for most aircraft, except for some military aircraft (such as the Lockheed C-130 Hercules), civil aircraft built before World War II (for example, the Boeing 247), and experimental vehicles such as the X-15. A cantilever wing's strength and rigidity are increased by dividing it into several shorter pieces known as "bulkheads". These are internal walls that divide the main body of the wing into smaller compartments. Each compartment can then act as a separate beam during flight, preventing damage from occurring along too many lines of weakness. Bulkheads often contain cross-members and other structural elements necessary to connect the various parts of the wing together.
