FIELD: testing of engines.
SUBSTANCE: bench comprises dynamometric platform mounted for permitting movements in three coordinate axes in the direction of load to be measured, load-bearing support secured to the bearing frame and interposed between the bearing frame and dynamometric platform, three dynamometric units for measuring horizontal, vertical and transverse component of thrust, and system for calibration. The dynamometric units are provided with a system for preliminary loading of the units and system for returning the platform to the zero position and control of linear displacements along the X-axis.
EFFECT: enhanced reliability of testing.
