Steam ejector system in high altitude test (HAT) facility

Steam ejectors are mostly used in variable applications such as propulsion, refrigeration, evacuation and aerospace. Ejectors are systems which are using to create vacuum. At the beginning of 20 th centuries, these systems are started to using by formulation of engineering design parameters. Steam ejectors are widely used in industrial and commercial applications. All in all, in this study, an ejector design is realized and this design evaluated in terms of aerodynamic properties. Any resistance analysis has not been carried in this design. During the designing of the ejector for high altitude rocket tests, some design models and parameters from technical litterateurs are considered. As a result, the main aim of this research is to design an ejector for high altitude rocket tests by determining the design parameters. Consequently, different usage areas of ejectors and ejectors for supersonic speed flows are investigated and reviewed to lead the project. After the completeness of design, flow analysis are carried on and results are evaluated.
