For decades the operational dynamics of the compression ring during operation, have been subject to debate [1, 2, 3, 4, 5, 6, 7]. A complex computer simulation, using Design Of Experiments (DOE) methodology, was developed to study the effect of the compression ring rotation during running-in stages. Response Surface (RS) has been used to optimize ring displacement, as function of ring mass, width and radius. The optimised surface response has been compared to used compression rings and has shown a 2% variation between calculated and measured values.
