Book Description
The primary purpose of Phase II of the ejector study has been to provide experimental data for engineering design purposes. The geometric and state parameters of the ejector were investigated over a wide range, both with and wfthaut diffuser. Variation in the ejector performance was determined for a change in primary temperature, and the effect of the use of a supersonic primary nozzle was also investigated. Comparisons of theoretical and experimental pumping performance without diffuser are presented.

Book Description
The feasibility of using an ejector with heated primary flow as a suction pump for boundary layer air removal from an aircraft has been investigated. Effects of some of the basic ejector geometric and state parameters were evaluated. The results indicate that while boundary layer removal by this method is feasible the aerodynamic benefits so obtained are accompanied by a measurable loss of primary jet thrust. Tests show the ejector to be relatively insensitive to the geometric parameters of primary nozzle location and mixing section length. Ejector performance for a given geometry was found to be a function of the primary momentum. The addition of a diffuser substantially increased ejector performance but was accompanied by greatly reduced thrust. Results indicate that an optimum geometry exists for each combination of flow conditions.
