Apparatus and method for fluid-screw system property measurement

A sensor mount apparatus for measuring at least one property of a screw-fluid system or components thereof, the components including motors, generators, bearings, shafts, propellers or fans, the apparatus configurable for a specific device under test, the device under test including at least one screw-fluid system component, the apparatus comprising:

• means for rigidly fixing the apparatus relative to an x-y plane and a z-axis perpendicular to the x-y plane;
• means for measuring at least one of a force load or a moment load transferred to the mounting base, selectively connected to said means for rigidly fixing the apparatus relative to an x-y plane and a z-axis perpendicular to the x-y plane;
• means for limiting at least one of the force load or moment load transferred to the sensor unit, selectively connected to said means for measuring at least one of a force load or a moment load transferred to the mounting base;
• and
• means for mounting the device under test to the apparatus so that any force or moment caused by a thrust or a drag from the device under test flows through the means for limiting to the means for measuring whereat the load is selectively measured, the means for mounting rigidly connected to said means for limiting at least one of the force load or moment load transferred to the means for measuring.
