Abstract:

The work completed under this contract included the design, fabrication, and installation of a Variable Fill Fluid Coupling VFFC Fan Drive with Electronic Speed Control into the M113A1E1 Test Rig Vehicle, as well as dynamometer hot room testing of the VFFC in the vehicle. Besides providing the control for modulating fan speed according to coolant temperature, the Electronic Controller EC limits the fan speed overspeed control to a preset maximum value, regardless of engine speed, and reduces control flow to a preset minimum value during low engine speed operation, regardless of coolant temperature.
