DATAWARE OF AIRCRAFT FLIGHT SAFETY IN VORTEX FIELD Russian patent published in 2012 - IPC G08G5/02 

FIELD: aircraft engineering.

SUBSTANCE: proposed method comprises air-air and air-ATC radio communication in broadcast mode and/or point-to-point mode with data transmission by every aircraft about parameters of vortex trail generated thereby and measured and/or calculated in onboard system of coordinates and receipt of said data by every other aircraft and/or ATC that are users in aircraft service area. Further, it includes calculation of said vortex tail effects in users' coordinate systems and analysis of said data by said users. Note here that vortex tail generator aircraft transmitted data includes vortex tail parameters in its onboard coordinates. Besides, transmitted are vortex tail generator aircraft speed and flight direction and time of data transmission while data receivers estimate chances of flying through said vortex field with due allowance for vortex field life cycle. If required, measured are characteristics of atmosphere and/or estimated are data sent by ATC system necessary for calculation of vortex tail. Note here that vortex field life cycle is defined by relationship T = π⁴ρVL³/4G, where p is air density, V is flight speed, L is aircraft wing span, b is distance between tail vortices, G is aircraft weight.

EFFECT: higher safety.
