AERODYNAMIC SCALE Russian patent published in 2014 - IPC G01G19/42 

FIELD: measurement equipment.

SUBSTANCE: invention relates to the field of experimental aerodynamics and may be used as three-component aerodynamic scale to measure and automatically register main coefficients of theory of similarity of different models. The substance of the invention is in placement of the scale in the open working part of the aerodynamic tube on a movable support with a holder for models, made in the form of a two-coordinate rod pendulum, in which the upper end is removed outside the contour of the aerodynamic pipe and via a cardan joint is connected to a strain gauge sensor of torque, installed on a wheel of a worm gear with a count scale. On the lower end of the rod holder there is a weight element in the form of a hydrodynamic damper with suspended weights and a recorder of a plane table of Lilienthal polars installed horizontally on the base of the frame support of the worm gear.

EFFECT: simplified design of scale, faster process of testing.
