Testing Challenge:

A Research laboratory desired an engine dynamometer that could test high-speed UAV engines to high torque diesels. The laboratory also desired short change-out times between engine test sequences.

Custom Engineered Solution:

Power Test’s Engineered Solutions Division developed a custom, 300HP (225kW) dual ended AC Regenerative dynamometer called the AC-300HS. This unique dyno has an extremely low moment of inertia and over 395 lb-ft (536N-m) in torque capabilities, in addition to speed capabilities of 12,000RPM.  The dual-ended machine allows the customer to have an engine under test on one side while setting up the next engine on the other for fast change-out.  High speed UAV engines are successfully run while modified Duramax diesels are right behind. The laboratory collects the precision data from the dyno to advance engine combustion research into the future.
