Abstract: |
This paper presents the new approach to the formation of
the gas turbine engine diagnostic matrix employing A.Tikhonov’s
regularization method and taking into account the compressor properties shift
under the condition of engine air-gas channel alteration. This method allows
eliminating the certain inadequacy of the diagnostic matrices in some cases
and removes the restrictions on their implementation for gas turbine engines
diagnostics. The elaborated regularization algorithm of the
calculation-identification matrix reversion permits to determine the
diagnostic matrix persistently. The suggested method of registration of the
compressor properties shift allows providing the adequacy of the engine
mathematical model taking into consideration the depreciation of the engine
and air-gas channel and consequently obtaining the
adequate diagnostic matrix. It is
offered to employ the obtained diagnostic model in the on-board systems of
the gas turbine engine control and diagnostics. |
