abstract

A physics based one-dimensional generic non linear dynamic model for a gas generator engine which is expected to enable future model based system oriented activities such as system control design, engine dynamic analysts, variable geometry optimization, air bleed extraction optimization, active surge and/or rotating stall avoidance control is presented. The model can be easily partitioned to obtain a one-dimensional compressor dynamic model which can simulate onset and development of surge and demonstrate existence of rotating stall. The notion of surge domain is introduced and it is shown how the dynamic model can quantitatively predict it. Other model predictions such as surge frequency and air bleed extractions are compared with experimental results.
