A lifting body is a foil or a complete foil-bearing body such as a fixed-wing aircraft. C L is a function of the angle of the body to the flow, its Reynolds number and its Mach number. The section lift coefficient c l refers to the dynamic lift characteristics of a two-dimensional foil section, with the reference area replaced by the foil chord ...
Fixed-wing aircraft – is a heavier-than-air flying machine, such as an airplane, which is capable of flight using wings that generate lift caused by the aircraft's forward airspeed and the shape of the wings. Fixed-wing aircraft are distinct from rotary-wing aircraft (in which the wings form a rotor mounted on a spinning shaft or "mast"), and ...
The Monarch Butterfly has a very low 0.168 kg/m 2 wing loading The McDonnell Douglas MD-11 has a high 837 kg/m 2 maximum wing loading. In aerodynamics, wing loading is the total weight of an aircraft or flying animal divided by the area of its wing.
A vortex is created by passage of an aircraft wing, revealed by smoke. Vortices are one of the many phenomena associated with the study of aerodynamics. Aerodynamics (Ancient Greek: ἀήρ aero (air) + Ancient Greek: δυναμική (dynamics)) is the study of the motion of air, particularly when affected by a solid object, such as an ...
The upward tilt of the wings and tailplane of an aircraft, as seen on this Boeing 737, is called dihedral angle. Schematic of dihedral and anhedral angle of an aircraft wing Measuring the dihedral angle. Dihedral angle is the upward angle from horizontal of the wings or tailplane of a fixed-wing aircraft.
Although the aircraft experiences high angles of attack throughout the maneuver, the aircraft is not capable of either aerodynamic directional control or maintaining level flight until the maneuver ends. The Cobra is an example of supermaneuvering [9] [10] as the aircraft's wings are well beyond the critical angle of attack for most of the ...
divergence where the aerodynamic forces increase the twist of a wing which further increases forces; control reversal where control activation produces an opposite aerodynamic moment that reduces, or in extreme cases reverses, the control effectiveness; and; flutter which is uncontained vibration that can lead to the destruction of an aircraft.
While the term originally referred solely to operating the aircraft, it has since been expanded to include technology, business, and other aspects related to aircraft. [1] The term " aviation " is sometimes used interchangeably with aeronautics, although "aeronautics" includes lighter-than-air craft such as airships , and includes ballistic ...
