NASA Airliner Wing Vortice Tests
Uploaded by: ATFSCrash
Video Description:
L-1011 Airliner Wing Vortice Tests at NASA Langley Research Center, notice how long the vortices stay active and how slowly they move.I should probably elaborate on what I mean by slow. I'm referring to the time between the airliner passing by and the reaction of the smoke.
This 58 second movie clip shows an L-1011 Airliner Wing Vortice test at NASA Langley Research Center.
NASA conducted the Adaptive Performance Optimization experiment aboard Orbital Sciences Corporation's Lockheed L-1011-100. The program was developed by engineers at the Dryden Flight Research Center. Dryden was also involved in limited wake vortex studies using an L-1011 in 1977.
The Adaptive Performance Optimization project is designed to reduce the aerodynamic drag of large subsonic transport aircraft by varying the camber of the wing through real-time adjustment of flaps or ailerons in response to changing flight conditions. Reducing the drag will improve aircraft efficiency and performance, resulting in signifigant fuel savings for the nation's airlines worth hundreds of millions of dollars annually.

| one more question; is it real time or slow motion? thank you..plane seems to pass very slow, that's why i think it may be slow motion, however the motion of the people at 0:34 suggests that it is real time... |

| It's real tine (or very close to it). The plane is flying slow to simulate landing speed. Each time the timer hand goes around is one second. |

| it's showing the dangers of landing a small craft to close behind something that big and how after that much time the air on the runway is still unstable from the plane that just landed. It's very dangerous to come in behind those big guys, even up to 60 seconds in some cases |

| U cant really see ... ( 9 months ago by ccrossey) |
| U cant really see it good from this angle, but the aircraft is relatively far back from the tower, it gives the vortices time to build up. Wing tip vortices, as they travel back behind the aircraft increase in magnitude and velocity, until they inventually interact and decay via the crow instability, in which vortex rings form. |

| because of the ... ( 1 month ago by 4wheeldrifting) |
| because of the distance. The plane was some distance away from the tower during the pass. The vortex takes time to propagate outward from the plane and contact the tower. This is so they can isolate the vortex and not have other effects caused by the aircraft disturbing the smoke. |

| Correct, Also the pilot overcorrected snapping the rudder. |
