Numerical and experimental investigation of the main parameters of a small gas turbine engine

Abstract

A numerical and experimental study of the main parameters of a small gas turbine engine is conducted in this paper. An experimental bench was developed for determining both the integral parameters (thrust and fuel consumption) of the gas turbine engine and the local parameters (temperatures and pressures) of its gas-air path. Besides, full-scale gas-turbine engine tests Jetcat P200-RX were done with and without gas-air path equipment. The existing small gas turbine engine sample was digitized and the gas flow in its gas-air path was simulated using the CFD method in a three-dimensional setting in ANSYS CFX. A comparative analysis of the results of full-scale tests and CFD modeling was carried out.
