A method for identifying the distributed rotor imbalance from aircraft engine vibrations measured on the casing of the engine is presented. The problem is heavily ill-posed. Nonlinear regularization techniques for linear inverse problems and nonlinear functionals are suggested for stable reconstruction algorithms.
