A Summary/Overview of Ejector Augmentor Theory and Performance. Volume 1. Technical Discussion
Abstract
The results of a 'Summary/Overview of Ejector Augmentor Theory and Performance, Phase II-Technical Report' are presented. In the Volume I-Technical Discussion, the results of the study are presented first in a description of the fundamental considerations relevant to ejector augmentor design and performance and second in a discussion of experimental results for the various components comprising an ejector augmentor: primary nozzles, secondary inlet, mixing section and diffuser. In the theoretical discussion a limit value of static augmentation ratio which depends only on the ratio of primary to secondary stagnation pressure is formulated, and it is shown that the best published experimental results approach 90% of the limit value. In the experimental section extensive data compilations are presented to provide a summary of the predominant geometric and gasdynamic parametric effects on ejector performance. Four ejector-augmentor flight systems (XFV-12A, XV-4A, XC-8A and the JW-1), are discussed in terms of the research and development programs leading to the prototype/demonstrator vehicles, and the actual vs. predicted performance. Conclusions regarding ejector technology based on this study are made, and recommendations for needed ejector technology research and development programs are presented.
