DIAGNOSTICS OF GAS TURBINE ENGINES BY THEIR EFFECTIVE CAPACITY

Abstract

The analytical solution was obtained reflecting the dependence of gas turbine engines effective power on their design and thermodynamic features as well as on parameters characterizing the engines operation conditions. This solution enables to determine the power developed by the engines based on the minimum information about their operation conditions. It is shown that for this it is enough just to get readings of regular meters. Using the received equation a procedure was developed for estimation of the engines technical state which enables to make such estimation on the probability basis and also in the extended option because it permits to get the engines power characteristic in expanded form.
