| Sumario: | There are shown the features of the development process of the digital engine regulator RDTs-450M-S-500 for the MS-500V-02S turboprop engine as another modification in the family of regulators for engines of helicopter and aircraft (including unmanned aerial vehicles). These regulators are developed and serially produced by Element JSC since 2014 year, when the Appliance Design Approval of the aviation equipment component was received for RDTs-450M type. The creation of a new regulator is described as a modification of the basic design with the simultaneous refinement of a specially developed aircraft engine universal stand-imitator, which provides adjustment and verification of the parameters of the regulator. Information about the requirements differences for the rotor vibrations control compare the previous regulator modifications is given. It is shown that during the development process the need for a significant engine mathematical model correction was revealed. Element JSC specialists corrected this model originally provided by the engine developer Motor Sich JSC. The results of this correction performed based on experimental data are reflected. The results of using a new engine mathematical model, including the metering pump mathematical model, are presented. It is shown that the integration of a new mathematical model into a universal stand-imitator provided RDTs-450M-S-500 regulator adjustment and subsequent successful tests of RDTs-450M-S-500 as engine part, which confirmed the adequacy of the model. During this test, ensuring of the turbocharger rotor acceleration given level was confirmed too. There is provided here information on the regulator qualification in the Aviation Register of the Interstate Aviation Committee, based on the results of which Supplement to Applliance Design Approval for the component were received and information on the preparation for certification as part of the MC-500V-02S engine at the State Aviation Administration of Ukraine. It is mentioned that the experience of JSC "Element" specialists forces them to note the need to strengthen the methodological support of the aviation equipment components developers from the State Aviation Service. |
