Database of ground-based anemometer measurements of wake vortices at Kennedy Airport A 7OO foot array of horizontal and vertical single-axis anemometers was installed at New York's Kennedy Airport on foot poles under the approach to Runway 31R.

Although the original purpose for the anemometers was to track the lateral position of wake Cited by: 3. Database of ground-based anemometer measurements of wake vortices at Kennedy Airport: final report / (Washington, D.C.: U.S.

Dept. of Transportation, Federal Aviation Administration, Office of Communications, Navigation, and Surveillance Systems ; Springfield, Va.: Available to the public through the National Technical Information Service. To help choose aircraft spacing based on the actual location and strength of the wake, it is proposed that wake vortices can be detected using conventional ground-based precipitation and cloud radars.

This is enabled by spraying a small quantity of water into the wake from near the healthtechdays.com by: 2. Sodar Measurements of Wing Vortex Strength and Position JFK International Airport shows that wake vortices in ground effect emit infrasound that is 1) more than 40 dB stronger than audible.

Analysis of the radar reflectivity of aircraft vortex wakes. can be detected using conventional ground-based precipitation and cloud radars. wind data and precise measurements of wake. Low-level wind shear, i.e., sudden changes in wind speed and/or wind direction up to altitudes of ft ( m) above-ground is a hazardous meteorological phenomenon in aviation.

It may radically change the aerodynamic circumstances of the flight, particularly during landing and take-off and consequently, it may threaten human lives and the health of passengers, people at the airport and its Author: Pavol Nechaj, Ladislav Gaál, Juraj Bartok, Olga Vorobyeva, Martin Gera, Miroslav Kelemen, Volodymyr.

This paper reports on a ground-based mechatronic system consist-ing of a cup and vane anemometer coupled to a guided airdrop system through a wireless transceiver. The guidance logic running on the airdrop system’s onboard autopilot is modified to integrate the anemometer measurements at ground level near the intended.

Lift-generated vortex wakes of subsonic transport aircraft. Author links open overlay panel Vernon J In order to better understand the structure and slow rate of decay of lift-generated vortices, measurements of the wake velocities were made in flight by Kraft in When measurements from ground-based facilities are compared with those in Cited by: Full text of "NASA Technical Reports Server (NTRS) Proceedings of the NASA First Wake Vortex Dynamic Spacing Workshop" See other formats.

Quantifying Wind Turbine Wake Effects on the Downwind Environment in Different Boundary Layer Conditions by Analyzing LIDAR and Surface Flux Spectra Laboratory Measurements of the Size Distribution and.

A passive infrared (IR) method will be developed for detecting and monitoring wake vortices in the vicinity of runways.

To establish a safe, fundamental method for detecting and monitoring wake vortices is crucial for increasing both flight safety and airport efficiency. The monitoring campaigns were conducted during March and MarchMost of the measurements were collected over short time periods ranging from 10 to 32 minutes.

The measurements taken during these campaigns were collected using portable battery operated monitoring devices. This banner text can have markup. web; books; video; audio; software; images; Toggle navigation.

The HSR, industry, and Tupolev team completed a remarkable proj­ect that accentuated the best possibilities of international cooperation. Against a backdrop of extreme challenges in the Russian economy, at a time when the value of the ruble declined over 80 percent from the time USPET arrived in Russia until it departed, all participants worked with a sense of commitment and fraternity.

Biographical Sketch. Tetsuya Theodore "Ted" Fujita () was born in Kitakyushu, Japan. After receiving his doctorate from Tokyo University inhe began a career as an associate professor at the Kyushu Institute of Technology.

Gravity is an important part of geodesy, with implications for height measurements and many other applications. In this module, we explore the concept of equipotential surfaces and relate them to gravity.

Then we discuss geodetic applications that rely on accurate gravity measurements, including leveling surveys and floodplain mapping. 01 Aerospace & Electronic Systems. The position is equipped with an additional workstation with a database of airport configurations under different weather conditions and the preferential routes among all major airports.

Wake Vortex Research in the USA (Wake Net-USA). NASA Technical Reports Server (NTRS) Lang, Steve; Bryant, Wayne. This viewgraph presentation reviews the cooperative work that FAA and NASA are engaged in to safely increase the capacity of the National Airspace System by studying the wake vortex operations.

Wake vortex avoidance is a limiting factor in defining separation standards.A goal of these studies was development of the measurement methods and algorithms necessary to detect wake vortex hazards in real time from either an aircraft or ground-based hyperspectral Fourier Transform Spectrometer (FTS).

This paper provides an update on .The WAVES investigation on the WIND spacecraft will provide comprehensive mea- surements of the radio and plasma wave phenomena which occur in Geospace.

Analyses of these measurements, in coordination with the other onboard plasma, energetic particles, and field mea.
