A fixed-wing aircraft may have more than one wing plane, stacked one above another: Biplane: two wing planes of similar size, stacked one above the other.The biplane is inherently lighter and stronger than a monoplane and was the most common configuration until the 1930s.
Structure of a plant cell. Plant cells are the cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae.Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or ...
The concept of the flying wing was born on 16 February 1876 when French engineers Alphonse Pénaud and Paul Gauchot filed a patent for an aero-plane or flying aircraft [5] powered by two propellers and with all the characteristics of a flying wing as we know it today. [6] Tailless aircraft have been experimented with since the earliest attempts ...
One promising approach that could rival slats are flexible wings. In flexible wings, much or all of a wing surface can change shape in flight to deflect air flow. The X-53 Active Aeroelastic Wing is a NASA effort. The adaptive compliant wing is a military and commercial effort. [7] [8] [9]

The gull wing, also known as Polish wing or Puławski wing, is an aircraft wing configuration with a prominent bend in the wing inner section towards the wing root. Its name is derived from the seabirds which it resembles and from the Polish aircraft designer Zygmunt Puławski who started using this design in his planes.
The wings of kites, [1] hang gliders, [2] paragliders, [3] powered kites, [4] powered hang gliders, ultralights, windmills [5] are aircraft that have versions that use ribs to form the wing shape. For full size and flying model aircraft wing structures that are usually made of wood, ribs can either be in one piece (forming the airfoil at that ...
