MODELING OF THE DYNAMICS OF THE SHIP GTE STARTING ON THE computer

G.F. Romanovsky, A.A. Tarasenko

An algorithm for modeling the dynamics of the process of starting a gas turbine engine (GTE) is proposed. In the simulation of the start the generalized characteristics of compressors, turbines, devices such as "gas-dynamic resistance" and bypass devices obtained by authors through the use of gas-dynamic functions and general relations are used. As the initial data parameters of the nominal mode are used. Example of calculation of the startup process is shown. The process is shown in the compressor characteristics in various capacities on the starter.

Key words: Start-up, compressor or turbine characteristics, consumption, efficiency, pressure ratio, the starter, bypass air device.
