Scientific paper

A method for describing small-scale turbulence in the mathematical modeling of the motion of a descent module is developed, and simulation test results pertaining to the descent of modules in the Venus atmosphere are examined. An analysis of data from characteristic segments of the descent of the Venera 13 and 14 modules shows that oscillations of the modules are quasi-planar with a constant orientation of the plane of oscillations, situated at an angle of 45 deg to the coordinate axes. This confirms the validity of analytical determinations based on the analysis of plane motion. Local decreases or increases in the amplitude of oscillations of the angular velocities indicate that atmospheric turbulence may indeed exist in the Venus atmosphhere, although it is not possible to numerically determine the turbulence parameters from the available data.
