چکیده انگلیسی
In order to carry out an experimental investigation on interactions between the compressor and the pulse detonation combustor (PDC) in a pulse detonation turbine engine (PDTE), an integrated system consisted of a four-tube PDC and a centrifugal compressor nominally rated for 1.05Â kg/s, 70,000Â RPM was set up and tested. The compressor was directly connected to the four-tube PDC. A radial turbine driven by a traditional combustor was used as the compressor's power input system to simulate the operating conditions of the compressor in a practical PDTE. Gasoline was used as fuel and compressed air from the compressor was supplied into the four-tube PDC. The Operability of the system is proved under the simultaneously and the sequentially firing patterns at frequencies from 20Â Hz to 30Â Hz. Pressure oscillations at the compressor exit are observed. Interactions between the compressor-PDC are revealed through the comparison of the compressor's parameters under different operating modes. The results indicate that the pressure oscillations will have a throttling effect on the compressor and change its operating points. Additionally, the firing of the four-tube PDC will push the operating line of the two components towards the surge line of the compressor.
