Abstract
Apparatus and method for monitoring operational performance of an engine, the apparatus comprising a sensor (10) for detecting torsional strain of a shaft (21) of an engine, and the apparatus further comprising a data processor arranged to process signals received from the strain sensor, and the data processor further arranged to compare one or more operational characteristics of the measured torsional strain data with idealised operational data so as to provide a measure of operational performance indicator of the engine.
Claims27
A method of analysing operational performance of an engine comprising use of at least one strain sensor attached to a drive shaft of the engine, the method comprising recording dynamic torsional strain data of the drive shaft during operational rotation of the shaft, and using the measured strain data to compare one or more operational characteristics of the engine with pre-determined idealised operational data, and deducing from the comparison at least one measure for use in determining an operational performance indicator of the engine.
