STAND FOR MEASURING THRUST AND REACTIVE MOMENT OF PROPELLER AND DYNAMIC CHARACTERISTICS OF PROPELLER WITH ENGINE Russian patent published in 2021 - IPC G01M15/02 G01L1/00 

FIELD: testing stands development.

SUBSTANCE: invention relates to a device for measuring the thrust and reactive moment of the propeller and can be used in the development of stands for testing propellers for air and water environment. The stand for measuring the thrust and reactive moment of the propeller and the dynamic characteristics of the propeller with the engine contains a base and a movable element installed with the ability to move relative to the base with a motor base on which the propeller engine is mounted, and a lever with which the force sensor is connected to determine the reactive moment, as well as a force sensor connected to the movable element for measuring the thrust. The movable element is made in the form of a shaft and is mounted on at least one support of rotation and linear movement along the axis of the shaft with the possibility of movement relative to the base and rotation around its own axis.

EFFECT: increased accuracy of measurements of the dynamic component of thrust and reactive moment of the propeller and its dynamic characteristics.
