Design Consideration for a Generic E.V.M. 912095

This paper discusses the design considerations for developing a Generic Engine Vibration Monitoring (EVM) unit which can be used for monitoring vibration on all gas turbine engines. The discussion is geared towards large commercial airplane engines, but the EVM is capable of monitoring industrial and smaller engines also. The advantages of this Generic EVM to airlines are fleet compatibility, reduction in spares and reduction in ground support equipment. The input/output requirements and the hardware and software trade-off decisions is addressed.
