Newton II Aircraft Powerplant Test Cell Mount 1999-01-1580

The study of piston aircraft engines with the propeller mounted as the load has been restricted due to the equipment needed to measure the combination of instant engine torque and vibrational movements. This work details the development of an engine mount that has a torque sensitivity of less than 0.05 pound-feet for measuring horsepower, vibration forces, and torque.
The hydraulic force measurement system used in the project is discussed and evaluated with the limitations encounter.
A torque balance system that can be checked with primary weights for absolute accuracy was developed and described as well as the methods for determining instant vibrational forces and rotational stresses.
