Testing of turbo-shaft engines requires power absorption devices that must be capable of stable operation at both variable powers and speeds (idle, take-off, cruise). A dynamometer transfers the engine shaft power to the incoming fluid and transforms it into thermal energy. An air-dynamometer has many advantages and is preferred over water brakes or electric generators, but must be made to operate stably over a wide range of speeds and powers.
