Inherent low inertia and quick transient response make the Kahn Series 102 dynamometers ideal for load testing of medium speed turboshaft engines, light turboprop engines, auxiliary power units (APUs), engine power takeoffs (PTOs), aircraft accessory gearboxes and helicopter transmissions. In many of these applications, time-consuming coupling shaft alignment is eliminated by mounting the dynamometer via adapters directly to the engine power output pad.
