Abstract

We propose a method for parameter identification of engine rotor mathematical model by non-contact way based on acoustic measurements. It is experimentally shown that the precision of this method is acceptable for engineering practice.

Keywords: identification, MATLAB, noise, engine rotor runaway, moment of inertia, time constant
