Two categories of ejector design have been investigated at de Havilland Aircraft of Canada: The paper reviews the underlying physical principles of the ejector type of thrust augmentor and suggests a logical procedure for development and optimization by experimental means. Methods of data analysis are shown which provide the foundation for empirical design and some examples of performance are given for each of the two ejector categories defined above. In addition, a new form of primary nozzle is described which serves to distribute the jet and promote fast mixing in the ejector throat.
