Experimental investigation of the vibration characteristics of four designs of turbine blades and of the effect produced by varying the axial spacing between nozzle blades and turbine blades

Morgan, W. C., Morse, C. R.

An investigation was made to determine the effects of varying the spacing between the nozzle blades and the turbine blades of a turbo-jet engine on turbine-blade vibration for four turbine-blade designs of different degrees of stiffness. In general, there was a tendency toward increase in occurrence of vibration with decrease in spacing. The effect was most evident in the case of the turbine blades that had greater stiffness.
