Closed wing designs include the annular wing (commonly known as the cylindrical or ring wing), the joined wing, the box wing, and spiroid tip devices. [ 1 ] Like many wingtip devices , the closed wing aims to reduce the wasteful effects associated with wingtip vortices that occur at the tips of conventional wings.
Swing-wing: also called "variable sweep wing". The left and right hand wings vary their sweep together, usually backwards. Seen in a few types of military aircraft, such as the General Dynamics F-111 Aardvark. Oblique wing: a single full-span wing pivots about its midpoint, so that one side sweeps back and the other side sweeps forward.
An aircraft with a cycloidal rotor wing is called a cyclogyro. Some examples are hybrids comprising a cycloidal rotor around a central Magnus cylinder. Cross-flow fan: a slatted cylindrical fan in a shaped duct. Longitudinal horizontal-axis. Radial-lift rotor: a substantially fore-aft axis rotor which creates lift through cyclic pitch variation.
The term chord is also applied to the width of wing flaps, ailerons and rudder on an aircraft. Many wings are not rectangular, so they have different chords at different positions. Usually, the chord length is greatest where the wing joins the aircraft's fuselage (called the root chord) and decreases along the wing toward the wing's tip (the ...
The symbol outline of the 313th Wing was a circle, that of the 58th Wing a triangle, and that of the 315th Wing a diamond. 20AF group letter identifiers: 58th Bomb Wing (triangle outline symbol): 40th BG - S, 444th BG - N, 462nd BG - U, 468th BG - I. 73rd Bomb Wing (square outline symbol, 10.5-foot letters):
The leading edge is the part of the wing that first contacts the air; [1] [2] alternatively it is the foremost edge of an airfoil section. [3] The first is an aerodynamic definition, the second a structural one.
The wingbox continues beyond the visible wing roots and interfaces with the fuselage in the centre wingbox, which forms the structural core of an aircraft. The wingbox is so called since, on many designs, the combination of the forward and rear wing spars and the upper and lower wing skins together form a natural "box" shape running through the ...
Radial (solid and colored lines) and circumferential roads (dashed and gray lines) in Metro Manila's road network. Axial – along the center of a round body, or the axis of rotation of a body; Radial – along a direction pointing along a radius from the center of an object, or perpendicular to a curved path.
