Experimental Investigation of Dynamic Identification and Control of Wall Pressure on Scramjet Combustor Model.
ICCMA(2017)
Abstract
For accurate aerodynamic thermodynamic regulation for scramjet engine, the state parameter wall pressure dynamic identification and control characteristics are investigated experimentally in this article. The dynamic responses of scramjet combustor wall pressure are stimulated by step input of kerosene under different conditions, then the transfer functions between the fuel and wall pressures measured in different locations are identified and dynamic, static characteristics are analyzed for control purposes. Based on designed control experiment system, the controllability and control characteristics of wall pressure are investigated in supersonic combustion conditions. Then the influences of fuel equivalence ratios(ER) and measurement locations are also contrastively studied. The control experiments and analysis results are given fundamental characteristics about the wall pressure control performances which are important in scramjet engine control engineering and performance optimization.
