Abstract
Benches are widely used in the process of creating automatic control systems (ACS) for gas turbine engines (GTE). The engine work is simulated via mathematical models. The model is supposed to be highly accurate in conditions of quite rapid calculation of the engine main parameters in both steady-state conditions and transient processes. A simulation model of a micro gas turbine Jet Cat P-60 engine is presented in the article. The model is based on the data obtained from generalized engine performance. A simulation model of a small-sized gas turbine engine is developed by plotting the rotor acceleration against the rotor rotational speed and the combustion chamber fuel consumption at each moment of time. The results of simulating the engine operation are compared with the experimental data obtained with increasing the GTE operation mode. The average modeling error value is obtained: 1.04% (ambient temperature is 288 K), 2.58% (249 K). It is acceptable for an adequate simulation of the GTE bench performance.
