Abstract
The diagnostic indicators of defects in aircraft gas turbine engines based on the vibration intensity have several draw-backs. Quite significant is the error in estimating such intensity. Moving an engine from the test bench to the facility leads to an increase in vibration intensity, which cannot be taken into account when developing diagnostic methods in the conditions of the engine manufacturer's plant. The known dimensionless discriminants have generally a fairly complex structure. This study reveals the possibility of using structural diagnostic indicators as a simple ratio of two parameters. Based on the example of tooth flank wear and the side clearance value in the turboprop engine gearbox, we have demonstrated the possibility to assess its technical condition by the vibration parameters and signals from standard tachometric sensors of the input and output shaft rotation speeds.
