Abstract: In some special cases of flight simulation (e. g. for formation flight, in-flight tanking) it is required to generate two-dimensional field of turbulence, in which the turbulent wind speeds are stochastic functions of two coordinates (e. g. x in the flight direction and y in the wing span direction). For this purpose a simple and efficient technique for digital generation of two-dimensional field of turbulence, i.e. for production of turbulent speed sequences on a rectangular network, is proposed in this paper. The correlation of so generated turbulent field is found to be in good agreement with the theoretical correlation of the Dryden model, thus the feasibility of the proposed method is verified. Two possible operation modes (off-line and on-line) of the turbulence generator in flight simulation are also discussed.
