wingtip vortices are created only when an aircraft is
Vortex - Wikipedia
In fluid dynamics, a vortex (PL: vortices or vortexes) is a region in a fluid in which the flow revolves around an axis line, which may be straight or curved. Vortices form in stirred fluids, and may be observed in smoke rings, whirlpools in the wake of a boat, and the winds surrounding a tropical cyclone, tornado or dust devil.. Vortices are a major component of turbulent flow.
Airbus A320 Family - Wikipedia
The Airbus A320 family is a series of narrow-body airliners developed and produced by Airbus.The A320 was launched in March 1984, first flew on 22 February 1987, and was introduced in April 1988 by Air France.The first member of the family was followed by the longer A321 (first delivered in January 1994), the shorter A319 (April 1996), and the even shorter …
NASA X-57 Maxwell - Wikipedia
The additional airflow over the wings created by the additional motors generates greater lift ... Such aircraft would have no in-flight ... the slender wing's chord is 2.48 ft (0.76 m) at the wing root and 1.74 ft (0.53 m) at the tip. rpm wingtip vortices, expected to provide a 5% drag saving. The 47 kWh (170 MJ) battery packs weight 860 lb ...
Horseshoe Vortex - Wikipedia
The horseshoe vortex model is a simplified representation of the vortex system present in the flow of air around a wing.This vortex system is modelled by the bound vortex (bound to the wing) and two trailing vortices, therefore having a shape vaguely reminiscent of a horseshoe. A starting vortex is shed as the wing begins to move through the fluid, which dissipates under the action …
Turbulence - Wikipedia
The onset of turbulence can be, to some extent, predicted by the Reynolds number, which is the ratio of inertial forces to viscous forces within a fluid which is subject to relative internal movement due to different fluid velocities, in what is known as a boundary layer in the case of a bounding surface such as the interior of a pipe. A similar effect is created by the introduction of a ...
Wake Turbulence - Wikipedia
Wake turbulence is a disturbance in the atmosphere that forms behind an aircraft as it passes through the air. It includes variety of elements, the most significant of which are wingtip vortices and jetwash. Jetwash refers to the rapidly moving gases expelled from a jet engine; it is extremely turbulent but of short duration.
Wingtip Vortices And Wake Turbulence - Pilot Institute
Mar 25, 2022 · The current system for classifying aircraft is based on weight, which, as described earlier, is not the only factor affecting the intensity of wingtip vortices. The new classification is based on a combination of aircraft weight, approach speed, and wingspan to give a more accurate representation of the wake produced by the aircraft.
Vortex Ring State - Wikipedia
The vortex ring state (VRS) is a dangerous aerodynamic condition that may arise in helicopter flight, when a vortex ring system engulfs the rotor, causing severe loss of lift.The vortex ring state is sometimes referred to as settling with power.The Federal Aviation Administration (FAA) sees these terms as synonymous, whereas Transport Canada sees them as two different …
The Dangers Of Wake Turbulence And How It's Managed By Pilots
Oct 12, 2022 · An aircraft that encounters the tip vortices of another aircraft, can experience something called wake turbulence. ... The downwash created by the tip vortices, tilt the lift vector as shown. Photo: ... Super (J): The only aircraft in this category is the Airbus A380, with an MTOW of 560,000 kg ; Heavy (H): ...
Wide-body Aircraft - Wikipedia
A wide-body aircraft, also known as a twin-aisle aircraft, is an airliner with a fuselage wide enough to accommodate two passenger aisles with seven or more seats abreast. The typical fuselage diameter is 5 to 6 m (16 to 20 ft). In the typical wide-body economy cabin, passengers are seated seven to ten abreast, allowing a total capacity of 200 to 850 passengers.
