Flywheel
When the engine drive line needs to include an inertia value to match that of the airframe transmission, a range of flywheels are available, with inertia values optimised to meet specific airframe requirements. Most flywheels are supplied mounted in a stand alone base frame. However, for certain applications they can be supplied fitted to the dynamometer half couplings.
Low speed 800 to 1,200 rpm pedestal mounted with grease lubricated bearings
Medium speed 6,000 to 10,000 rpm pedestal mounted with grease lubricated bearings
High Speed 14,000 to 24,000 rpm pedestal mounted with oil lubricated bearings
Ultra High Speed 24,00 to 30,000 rpm pedestal mounted with oil lubricated bearings
