| Abstract: | A laser holograph and image processing method was used to analysis
the striking and spray properties of unlike double impinging injector.The spray characteristics
were obtained.The spray properties and combustion efficiencies of combustion chamber were
statistically analyzed,the relationship between the water test spray property and the hot run
performance was found.The following results were reached during the research:the water test
spray property can be used to evaluate the hot run performance and examine injector
performance.The method has been used for selection and quality inspection of injectors of
small thrust liquid propellant rocket engine. |
