FIELD: measurement equipment.SUBSTANCE: measuring device of impulse reactive thrust of low thrust liquid propellant engines (LT LPE) contains a heavy rig installed by means of shock absorbers on a power support of the test bench, a loading frame, to which a force transmitting frame for attachment of LT LPE is connected, which are installed coaxially and have the possibility of being moved relative to the rig along the main measurement axis of the device, two belts that are adjustable as to length and flexible as to the main measurement axis and transverse suspensions arranged perpendicular to it and connected with some of their ends to the rig, as well as setting device of calibration force of reference of static force and an operating dynamometer, which are installed coaxially to the main measurement axis of the device and axis of LT LPE. The loading frame has a closed and a stiff shape in the form of front and rear traverses connected by means of tie rods, located on opposite sides of the rig, to which the other ends of flexible transverse suspensions are connected; at that, the force transmitting frame is fixed on the outer side of front traverse of the loading frame, and the calibration force setting device is installed on its inner side. Spherical hinge of its power output stock interacts with the rig, on the opposite side of which the operating dynamometer is installed, with which the spherical hinge of force receiving stock fixed on rear traverse of the loading frame interacts.EFFECT: improving the device accuracy and operability.3 cl, 4 dwg |
