Paternoster Vents, sometimes referred to as simply Vents[1][2][3][4] and also known as Angel's Wings, [5][6] is an outdoor 2002 stainless steel sculpture by Thomas Heatherwick, installed ...
The Su-47 uses a forward wing sweep, while the Su-27s sport a more conventional backward-swept design. A swept wing is a wing angled either backward or occasionally forward from its root rather than perpendicular to the fuselage. Swept wings have been flown since the pioneer days of aviation. Wing sweep at high speeds was first investigated in ...
A variable-sweep wing, colloquially known as a " swing wing ", is an airplane wing, or set of wings, that may be modified during flight, swept back and then returned to its previous straight position. Because it allows the aircraft's shape to be changed, it is an example of a variable-geometry aircraft. A straight wing is most efficient for low ...
Angels in art. Ezekiel's "chariot vision", by Matthaeus Merian (1593–1650), displaying several different types of angelic creatures. Angels have appeared in works of art since early Christian art, and they have been a popular subject for Byzantine and European paintings and sculpture. Normally given wings in art, angels are usually intended ...
Dihedral (aeronautics) The upward tilt of the wings and tailplane of an aircraft, as seen on this Boeing 737, is called dihedral angle. Dihedral angle is the upward angle from horizontal of the wings or tailplane of a fixed-wing aircraft. "Anhedral angle" is the name given to negative dihedral angle, that is, when there is a downward angle from ...
A duck with angel wing A Muscovy duck with angel wing. Angel wing, also known as airplane wing, [1] slipped wing, crooked wing, and drooped wing, [citation needed] is a syndrome that affects primarily aquatic birds, such as geese and ducks, in which the last joint of the wing is twisted with the wing feathers pointing out laterally, instead of lying against the body.
The Angel of the North is a contemporary sculpture by Antony Gormley, located in Gateshead, Tyne and Wear, England.Completed in 1998, it is believed to be the largest sculpture of an angel in the world and is viewed by an estimated 33 million people every year due to its proximity to the A1 and A167 roads and the East Coast Main Line.
Wingtip devices help prevent the flow around the wingtip of higher pressure air under the wing flowing to the lower pressure surface on top at the wingtip, which results in a vortex caused by the forward motion of the aircraft. Winglets also reduce the lift-induced drag caused by wingtip vortices and improve lift-to-drag ratio.
