Abstract
The disclosure illustrates a closed loop aircraft transmission test set comprising a variable speed DC motor driving a speed changing gear box whose output shaft is coupled to the input of the transmission under test, the main output shaft of the transmission being coupled to a DC generator load, the output of the generator being used to supplement the input electric power used to operate the DC driving motor thus assuring power drain from the supply busses is only the amount needed to overcome system friction and efficiency losses.
