BENCH FOR DETERMINATION OF ROTARY PRODUCTIVE AERODYNAMIC FORCES AND MOMENTS OF MODEL IN AERODYNAMIC PIPE

摘要

FIELD: measurement equipment.;SUBSTANCE: invention relates to experimental equipment for detection of rotary productive aerodynamic forces and moments of the model in an aerodynamic pipe, also near a screen. The bench comprises a model with a strain-gage weigher, installed on the stand with a stem, and a mechanism of its movements. It also comprises an energy drive in the form of a linear electric motor with an extended traction rod, by means of a lever and a double-link mechanism with a leash, which is kinematically connected by the second link in its turn to a model. Arrangement of the kinematic joint of the second link of the double-link mechanism in the form of a bracket installed on the stem or in the form of a slider with brackets provides for oscillations of the model by height and at angles of pitch or list. Equipment of the bench with a screen moving in guides with a slot for a stand with a stem provides for tests near the screen.;EFFECT: expansion of bench capabilities in production of rotary productive forces and moments.;8 cl, 9 dwg
