The propeller dynamometers are new designs to replace earlier dynamometers only adjustments to the inclination of the propeller shaft could be made, but with the introduction of the adjustment of propeller shaft height can also be achieved. Depending on the maximum capacity of the drive motors, the maximum torque ratings, and consequently the diameters of the propeller shaft ends, are different. The capacity of the drive motors of the same whereas that of less. Apart from the different arrangement possibilities,the technical details of all essential parts of propeller dynamometers are identical, with exception of the capacity of the drive motors and the maximum load ratings in respect of measurement of torque and thrust.

The dynamometers can be supplied with the standard height of the vertical streamlined profile or with an increased height of the vertical streamlined profile as described below. The three dynamometers are of the same general type but differ in size and capacity as shown below. Full technical details of the dynamometers are provided below.
