Abstract
A dual rotor rig is developed and is briefly discussed. The rig is cap able of simulating dynamically the two spool aeroengine, though it doe s not physically resemble the actual aeroengine configuration. Critica l speeds, mode shape, and unbalance response are determined experiment ally. An extended transfer matrix procedure in complex variables is de veloped for obtaining unbalance response of dual rotor system. Experim ental results obtained are compared with theoretical results and are f ound to be in reasonable agreement.
