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.

Available in PDF, EPUB and Kindle. Book excerpt: A nonlinear analog simulation of a turbojet engine was developed. The purpose of the study was to establish simulation techniques applicable to propulsion system dynamics and controls research. A schematic model was derived from a physical description of a J85-13 turbojet engine. Basic conservation equations were applied to each component along with their individual performance characteristics to derive a mathematical representation. The simulation was mechanized on an analog computer. The simulation was verified in both steady-state and dynamic modes by comparing analytical results with experimental data obtained from tests performed at the Lewis Research Center with a J85-13 engine. In addition, comparison was also made with performance data obtained from the engine manufacturer. The comparisons established the validity of the simulation technique.
