Abstract	At the request of Mr. E.S. Moore, Manufacturing Technology Centre, the critical speeds of an experimental rotor design have been determined. The rotor is being designed to test a split entry fan concept from Rolls-Royce Ltd., Derby, England. As the rig design is in the conceptual stage at present, it was necessary that a broad range of assumptions and engineering estimates be made as inputs to the calculations. This memorandum describes these input estimates and their effect on the calculated critical speed of the system.
