Download or read book Study of Turbojet Combustor Dynamics Using Sweep-frequency Data written by John R. Szuch and published by . This book was released on 1970 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: The analysis of data obtained from sweep-frequency testing of the 585 turbojet combustor is discussed.Bode plots of the response of combustor pressure to sinusoidal disturbances in fuelspray- nozzle pressure are presented for a range of fuel flows. An analog simulation was developed and used to match the experimental data and to identify the combustion dynamics. The effects of primary or burning-zone fuel-to-air ratio on the system response were also investigated. The experimental data were fit by linear transfer function forms to be used in overall system studies.
