Wingtip vortices. Turbulence caused by difference in air pressure on either side of wing. Lift-induced vortices behind a jet aircraft are evidenced by smoke on a runway in an experiment by the German Aerospace Center (DLR) An audio recording of lift-induced vortices heard shortly after an airliner flew over the recorder.
The wing configuration of a fixed-wing aircraft (including both gliders and powered aeroplanes) is its arrangement of lifting and related surfaces. Aircraft designs are often classified by their wing configuration. For example, the Supermarine Spitfire is a conventional low wing cantilever monoplane of straight elliptical planform with moderate ...
Spar (aeronautics) In a fixed-wing aircraft, the spar is often the main structural member of the wing, running spanwise at right angles (or thereabouts depending on wing sweep) to the fuselage. The spar carries flight loads and the weight of the wings while on the ground. Other structural and forming members such as ribs may be attached to the ...
F1B Model by Stepan Stepanchuk. Free flight is the segment of model aviation involving aircraft with no active external control after launch. Free Flight is the original form of hobby aeromodeling, with the competitive objective being to build and launch a self controlling aircraft that will consistently achieve the longest flight duration over multiple competition rounds, within various class ...
Fixed-wing aircraft. A Boeing 737 airliner is an example of a fixed-wing aircraft. The fixed wings of a delta -shaped kite are not rigid. A fixed-wing aircraft is a heavier-than-air aircraft, such as an airplane, which is capable of flight using aerodynamic lift. Fixed-wing aircraft are distinct from rotary-wing aircraft (in which a rotor ...
