EJECTOR, AND HIGH-ALTITUDE COMBUSTION TEST EXHAUST EQUIPMENT HAVING THE EJECTOR

摘要

PROBLEM TO BE SOLVED: To provide an ejector capable of sucking an object fluid efficiently and a high-altitude combustion test exhaust equipment having the ejector.SOLUTION: An ejector comprises: a pipe conduit having a curved section, in which an object fluid flows in a first direction; and a nozzle that is an annular passage covering the outer circumference of an end part of a first direction of the pipe conduit and arranged on the outer circumference of the pipe conduit, so that a drive fluid flows in a first direction. The conduit has a convex-concave shape, of which the radial position of the inner circumference of the end part varies in accordance with the circumferential position.SELECTED DRAWING: Figure 3
