METHOD AND DEVICE FOR MEASURING AIR TURBULENCE IN THE SURROUNDINGS OF AN AIRCRAFT

摘要

Method and device for measuring the turbulence of the air in the environment of an aircraft. The device (1) comprises a measurement system (2) comprising lidars (L1, L2, L3, L4) which are mounted on the aircraft and which are intended to carry out during a flight of the aircraft twelve measurements of aerodynamic speed in the external environment of said aircraft, said measuring system (2) carrying out said twelve measurements at four different measuring points, each time along three predetermined axes, and a central unit (3) which, using the measurements made by said measuring system (2) and a predetermined first-order mathematical model describing an aerodynamic velocity field according to twelve variables, determines an aerodynamic velocity field that exists in said aircraft environment, and which is representative of said air turbulence.
