METHOD OF CONTROLLING FLEXIBLE WALLS OF NOZZLE OF WIND TUNNEL

摘要

FIELD: physics; control.;SUBSTANCE: invention relates to experimental aerodynamics, particularly wind tunnels with controlled nozzles. The method involves controlling flexible walls of the nozzle with automatic drive mechanisms according to a given program. The task of changing the outline of the nozzle in form of a given number M is transformed to the end position of a lead series, and control of the lead series is carried out synchronously in a function of the position of the lead series given at the present moment in time.;EFFECT: high accuracy of installing flexible walls of a nozzle of a wind tunnel, low power consumption of drives, reduced tension in the flexible walls and easy use of the nozzle.;2 dwg
