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.
