1/4

 

WINDEX-5000 Pulse Doppler Wind LIDAR is a reliable and high-precision tool for real-time monitoring of wind fields in the surface atmosphere layer. Based on the monitoring results it detects dangerous wind phenomena (wind shear, intensive turbulence areas, wake vortices behind aircraft), data transmission and automatic users notification on hazardous phenomena.

Developed in accordance with IEC and ISO international requirements, as well as national standards. The LIDAR operates in an invisible to the human eye range, and is a safe laser product. The LIDAR possesses the IAC certificate, the Pattern approval certificate of measuring instruments of Rosstandart and the estimation from Rospotrebnadzor.

WINDEX-5000 allows to:

  • perform 3D-mapping of wind fields

  • determine vertical profile of the wind speed and direction

  • determine the turbulence level of air flow

  • identify the horizontal wind shear and vertical gusts

Scanning modes:

  • Plan Position Indicator (PPI) - a circular scan in a given range azimuth angles with a constant angle of elevation

  • Range Height Indicator (RHI) - scanning in the vertical plane in a predetermined range of elevation angles with constant azimuth

  • Measurement of vertical wind profile

Selection and control of scanning modes are operated via software included in the delivery package which provides formation of arbitrary measurement cyclograms according to Customer’s needs.

  • environmental monitoring

   Low Level Wind Shear Alerting System

Low-Level Wind Shear Alerting System (LLWSAS) is designed to increase flight safety level during takeoff and landing operations through real-time remote sensing and display of information on vector direction and speed rate of air flow at given altitudes, as well as detection of low-level wind shear turbulence, and issuing timely alerts for all airspace users, including crews of aircraft.

LLWSAS ensures:

  • remote measurement of the wind condition characteristics, including wind speed and direction in the scanning sectors

  • measurement and display of the counter / tail wind speed component relative to the current landing courses

  • wind shear characteristics determination (wind shear intensity and its spatial localization) according to one of the following criteria as selected by the user:
    - according to the variation of the counter / tail wind speed component relative to the current landing courses
    - according to the variation of the wind speed rate
    - according to the variation of the wind speed and direction

  • identification of the gust front position

  • detection of the intense turbulence zone

  • generation and transmission of messages on detected hazardous wind phenomena

  • operation of up to 10 LIDARs both in the hot standby mode and in independent setting of scanning cyclograms

  • display and record of the scan results for each LIDAR of the system

  • flexible configuration for multi runway airports

  • automated scan cyclogram formation for trajectories of ToL operations

   Wake Vortex Measurement System

Wake vortex measurement system based on WINDEX-5000 Pulsed Doppler Wind LIDAR provides possibility to detect wake vortices behind aircraft including online automatic wake characteristics determination.

The wake vortex measurement system based on WINDEX-5000 pulsed Doppler Wind LIDAR may be used as:

  • automated wake vortex data collection for aircraft separation distances optimization according to the wake vortex turbulence for particular airport

  • part of the dynamic aircraft  separation according to the wake vortex turbulence for particular airport

The specifics of wake vortex behind an aircraft is that the airflow speed components disturbed by the wake vortex have the highest velocities in the perpendicular plane to the aircraft flight path. Therefore the main scanning mode for the purpose of wake vortex measurement is RHI. Herewith, the system allows setting the scanning parameters according to the particular installation site to achieve the best measurement results.

Wake vortex measurement system is a key element for airport capacity increase by narrowing the separation minima on Takeoff and Landing. London Heathrow airport is a remarkable example of such system implementation where millions of Euro are saved annually. The precise information about wake vortices behind the plane not only increases the airport capacity, but at the same time improves flight safety.
