Abstract: The present invention relates to an apparatus for testing strength and airtightness for a regenerative cooling combustion chamber, which is installed inside a combustion chamber by being opposite to a film cooling hole of the combustion chamber, and comprises a mounting ring where an accommodating groove is formed to communicate with the film cooling hole; a first elastic unit which is inserted into the accommodating groove by being opposite to the film cooling hole; and a second elastic unit which is inserted into the accommodating groove, whose outer circumference is in contact with the inner circumference of the first elastic unit, and whose left and right circumferences are separated from the accommodating groove. The apparatus for testing strength and airtightness for a regenerative cooling combustion chamber can facilitate a test and prevent safety accidents of a testing person by supplying pressure at a higher strength than the regenerative cooling combustion chamber formed with the inner skin and the outer skin and at a higher pressure than an airtightness test and by sealing the film cooling hole during the airtightness test.

Abstract translation: 本发明涉及一种通过与燃烧室的薄膜冷却孔相对的方式安装在燃烧室内的再生式冷却燃烧室的强度和气密性的测试装置，包括形成容纳槽的安装环 与薄膜冷却孔通讯; 第一弹性单元，其通过与薄膜冷却孔相对插入到容纳槽中; 以及第二弹性单元，其插入到所述容纳槽中，所述第二弹性单元的外周与所述第一弹性单元的内周接触，并且其左右周与所述容纳槽分离。 用于再生冷却燃烧室的强度和气密性的测试装置可以通过以比内皮和外皮形成的再生式冷却燃烧室更高的强度提供压力来促进测试人员的安全事故，并且以 比气密性试验更高的压力和在气密性试验期间密封薄膜冷却孔。
