摘要：

Results of an experimental study of the operation process in a model of an air-breathing combustor operating on heated kerosene with a supersonic air flow at the combustor entrance (Mach numbers 3 and 3.5) are presented. The tests are performed in a hotshot wind tunnel in the attached pipeline configuration with total temperatures of 2350-3250 K and pressures of 3.2-12.0 MPa. Data on ignition conditions and kerosene combustion efficiency are obtained. A principal possibility of using Ozawa's criterion and its modification for the description of the range of stable combustion of the kerosene-air mixture in a combustor duct with flame holders shaped as cavities and steps in an essentially three-dimensional flow is demonstrated.
